Topic: Setting Up Front Imaging

Posted By: tubbs04
Subject: Setting Up Front Imaging
Date Posted: March 11, 2008 at 7:56 AM

I've started the build on my pods and it's time to position my rings. I'm trying for the best SQ possible with this build. I've heard to aim the drivers at the dome lights in the vehicle, but I've got 2 sets, one over my shoulder when I'm in the drivers seat, and then one set directly in front of the windshield in this overhead console. So should I aim them over my shoulder or more towards the front? I want the staging to be as wide as possible and sound like its coming from the front of my hood. I'll also be running two or three sets of tweeters. One in the stock location by the 6.5 component, one in the A pillar, and possibly a 3rd mounted on the top of the door panel firing up. I've got a '97 tahoe, 4 door and there will be a 6.5 component and a 6.5 mid driver in each door. Any information would be very helpful.

Thanks
tubbs

Those are HORIFFIC locations if you want your stage to sound like it's on the hood. If TRULY interested in sound quality, ONE SET OF SPEAKERS, placed high in the doors, with woofer/mid/tweeter all placed as close as possible to one another, is best.

Keep all those extra tweeters for paperweights or refrigerator magnets, they have NO PLACE WHATSOEVER in a "sound quality" build.

hmmmm... I can only get about half way up the panel as far as bringing them up as high as possible. So no tweeters in the A pillars? I figured that would help putting the sound out front. Do either of you have pics of your set up online? I honestly have no clue when it comes to speaker placement, or really anything having to do with "SQ"... (I'm sure both of you all ready guessed that.) I think if I could see what ya'll are saying it would help. Thanks for the replies.

I've seen that before. What I meant to ask is if you had a picture of the install so I could see how everything is positioned. I see you use a CD8445... I have a CD8443... have you ever played with the e-commander??? I bought one N.O.S. from the local jl/eclipse dealer for $50... havent had a chance to play with it yet.

I think I'm starting to see the errors of my ways buying the stroker, and gobs of components... I could have bought some focals for the front with what I've spent on the tons of MA stuff I have... I hope I get it right someday hahaha....

In that link (inside the thread) were more links to pictures of my doors, I just don't remember really where they were... Sorry.

The 8443 is a really nice deck, too, I swapped my 8445 for an Alpine w205. I wanted nav... posted_image

Never did have a chance to play with the e-commander. Thought about buying one, and if I'd tripped across one for 50 dollars, I'd have bought it INSTANTLY! That's a smokin' deal!

eBay is the BEST, baby! Sell that stuff, even if you have to take a loss, and get some good products, and I don't mean Focal. Those things are WAY too bright. Build your own sets, crossovers aren't THAT difficult, and you can build way better for WAY less than you can buy a set of Focals for... I did.

As far as staging? It can be achieved in ANY car, and I do mean ANY. Careful placement, alignment, and crossover points are key to this. No kick panels... DOORS. No A-Pillars... DOORS. No rear decks... DOOOORS!!!

Full active systems are much easier to do it with, (at the expense of funds) but it can be done quite effectively with passive systems, also (at the expense of some other parameters).

How much:
A) can you get for what you've GOT, right now? and
B) more will you want to spend?

We can get you there... No, really!

Sorry... I should have read farther into the post... nice build!

I can probably return the stroker to my store... thats about $270... I'd sell the HK598 4Ch for $150 and the HK1000D for another $150. I've got 2 pairs of MA mid drivers I'd let go for $30 a pair and the components for the same.

That would free up roughly $650... I've got an older eclipse 4 ch (3442 I think) puts out about 50 watts at 4 ohms That I could use for the front. I've learned about sensitivity and thats why the MA mid drivers don't respond on that amp... the sensitivity is crap on them....

I'd be willing to put roughly another $500 - $1k into it, couldn't do it all at once though. Not sure how far that will get me in your world but I'd love to try! I was just using the focals as a reference. I honestly don't care about names. I want to put together a system that makes people sit back and say "damn." I'm past making as much noise as possible. I've done that for years. I want clean.

thanks for the help man. I really appreciate it.

Thanks... I worked a long time on that one!

Hmmm... $1K, minus 300 (keeping the MA amps - while not spectacular, they'll get you through, till you can buy something better) leaves you seven notes, and you already have TWO amps for the fronts, and the amp for the sub! You're well on your way! I had one of the 3442s, and it's a pretty damn nice amp... two chanels for some good mid-bass, actively crossed, and the other two channels for a nice mid/tweet with good passives, a decent amp/sub system, you're set...

We can do this, AND get you some "name brand" cables in there, too, just for "bling"...

A pair of TC-1000 12's (or something like those, maybe some Daytons), some Tang-band 7's, a pair of Silver Flute 5 inch mids, and a good set of tweeters... Done, man! I'll research sources and costs a bit more tonight, and get back with ya!

I don't know the exact specs to it, but I could measure and find out. I've been thinking about going sealed, but I'd entertain any idea you have to offer.. Thanks again!

Here's your mids...

Here's the woofers...

A pair of these, paralleled...

Tweeters...

Look those over, and let me know if you think you can afford that as a setup... If you like the money, we'll go forward, but I think you'd be REALLY happy with the overall performance of that stuff. Like I said, keep the amps you presently have, we'll use those!

I ordered everything but the woofers like 2 seconds ago. I'm going to have to wait a minute before I run with those. That HK1000D I have wont put out the power those dayton's require at 4 ohms. It'll do it at 1ohm, but not 4. Suggestions? or do you allready have a plan for that??? Thanks for the help. I know you weren't ignoring me, We've all got lives outside of the12volt.... or do we... hahaha... Thanks dave!

The HK1000 will put out 500WRMS (claimed) at 4 ohms. Plenty, and that's probably FAR more accurate and significantly less optimistic than the 1kW claimed for the 1 ohm load. PLUS, your damping factor will remain really high, so the control will be better.

If really worried about the difference in power, get the 4 ohm versions of those woofers... easy enough to answer that question!

MA rates the amp at 1kw @ 1ohm @ 17 volts....  I hate how they advertise.. you have to read the book before it mentions 17 volts.... at 14.4 it claims 750-800 @ 1ohm... If you say 8 ohm then we'll go 8 ohm. Would sealed or ported be the better application for the subs? Or something different?I'm down to build whatever enclosure I need too...  What are your plans for crossovers? Thanks man!

Those Tang Band woofers are regularly $67 and are now $29. Not sure if I even need them, but I almost want to buy them just because you reccomended them and they are such a slammin deal!  Thought?

My thought is this... I'm ordering 4 to have in spare... I already have 4, they WERE gonna be used in place of the Adires, (in my car) but I still just have 'em hanging around. I'll probably end up (someday) finishing my 41hz.com Class T 6 channel amplifiers, and have me a STUPID wicked multimedia system! LOL

In response to your PM... If you do use those tweeters, you may or may not end up with a desirable result. I'll finish directly to you.

No, the crossovers will not be available as a kit, but since yopu will be all active, with didicated amp channels, you won't even have to put them on a circuit board... Build each section (HP, LP, MID) right in the speaker line. It'll be easy! I did it EXACTLY that way with several of my past systems, and the results were QUITE satisfying!

We'll get ya fixed up on those, no worries!

speakers should be in tuesday... i'm excited to see where this is going.... Would you care to explain to me why you recomended those exact speakers? I was suprised to see that the silver flute speaker had a wool cone. I've only seen the typical aluminum, pressed paper, and kevlar style cones.

Anyways, I'll let you know when they come in. I don't want to jump the gun on anything.

OK... Lemme know what you want in the way of install locations. Ideally, you will want a straight line with the woofer at one end, and your ear at the other, with mid/tweeter array between.


:::::EDIT:::::
Doh. I should read a little more... you said they were in...

Anyway, what did you do as far as wiring? Did you leave plenty?

I don't exactly understand " woofer at one end, and your ear at the other, with mid/tweeter array between."

I'm building some door pods. I was hoping to mount the vifa half way up the panel  in front of the stock tweeter location, with the silver flute under that, and the tang-band under that. Do I need to run them sealed, ported, IB, or some funky other enclosure that I don't know about yet???

The only wiring I have in my truck is the factory wiring. It hasn't been cut or hacked away. I have a single strand of 4 ga to the sub amp and a single strand of 8 ga to the 4ch. I have 20" of 9 con (18 ga.) that Im just dieing to run through the truck. If running individual strands of thicker wire would be better I can do that as well (I have Tsunami stuff avalible). I've also got a new kicker 0 ga (is that over kill for this project?) kit that I want to run through my truck. I AM FULLY PREPAIRED TO PULL THE INTERIOR!!!

The car audio buyer for my company came by today and I had the speakers sitting in my office. He took one look and said, "man, you're trying to do something right!" I told him you were helping me with the process, and he was impressed. He's also building a SQ truck, that I'd love to run against in may at our 1st USACi show of the year. He's doing up an chevy avalanch with some wave guides and lord knows what else... his bugette is WAY bigger than mine (plus he's been in the business and installing for the past 25yrs)..... hahahaha!

Thats the link to where I've got the start of the pods posted. I plan on posting the build here once it's finished. Thanks dave!

Those pods look like a sweet start!

The drivers will all be in basic open-back installation... IF you can get the mid sealed away from the door cavity, that'd be best... The description of what you have in mind for the mid install works perfectly, I think... So, ideally, you'll have TangBang in IB, SilverFlute in a small sealed cavity, with a bit of stuffing, and the tweeter will be a sealed back (won't really matter, tho... it's already sealed from the back) The most important spacing here is the mid/tweeter... They NEED to be as close together as is practical, and the mid's edge should be (ideally) no further from the woofer's edge than 5 or 6 inches. (And I am talking about the CONE, not the basket...) Closer is better!

Also, if you can "tip" the mid and tweeter, say 10 to 15 degrees, especially on the driver's side, to point a little bit more toward your ears, ("toward the dome light", as you said early on) that'll GREATLY help your sound power.

Here is what I was talking about with the "array"...
posted_image

Now... refresh my memory as to what signal processing you have, please? I mean everything in the deck, any external procesors, and whatever crossovers are available in the amps...

IIRC, we will be active at the sub to TB, active with the TB to SF, and passive low-pass on the SF, and passive high pass on the Vifa... Do I, in fact, remember corretly? These will also have 6 discrete channels of amplification, as well... Right? If so, then wou will be running 3 pairs of speaker wire to each door. (Leave plenty of extra for the mid and tweeter, so we can insert the passive crossovers right there at the driver - this will prevent any cable interaction from affecting the driver and crossover response) Anything over 18 gauge will be plenty, but bigger looks cooler, I think... Judges like the bling, too! posted_image

And if you wanna brag on my system to him, let him know I am IASCA SQ registered, too, and as soon as I can GET to a meet, I'll do so! (I do have to do a bit of re-tuning, tho... something doesn't sound "quite right" lately...)   Gah... wave-guides... blech! Never been a fan! I personally don't believe there is adequate space in the automotive environment to effectively apply horns. (Don't tell him I said that! posted_image )

I don't have any external eq's or anything like that.... Just straight cdplayer to amps... should I invest in one?

Ya, I showed him your build and he did compliment it. He did mention that he had to cut the wave guides all the way down to even sit in the truck and he was rebuilding the power supply on a behinger 31 band eq so he could tune them in some more.

When you say a small sealed enclosure are we talking .1-.3 cu ft? I've come up with a way to mount and seal the SF before wrapping the rest of the pod for glass. I can then cut the back to run the TB IB...

It's time to start building again!!!

Did a little trimming on the molds today to get them symetrical. I've got a pretty good design in my head for the install. I was thinking the sealed part of the pod for the SF should be around .1cuft... let me know if that's wrong so I can adjust my design.

Thanks dave!

Being as it is a mid driver, that should be a perfectly adequate volume. If you can spray a bit of damping on the interior of the mid's volume, or line it with a felt, that'll help. You'll be putting some amount of stuffing in there, as well. Not much, but some. That'll help keep that small volume from ringing, especially considering the frequencies you will be running!

sounds great. did you get to go over the amps and everything I listed?

I'll be making the rings tomorrow and hopefully positioning them. obviously the mid and tweet need to be at the same angle, but would it mater if I mounted the tweeter say 2" off the panel, the mid 3-4" off the panel and the woofer 4-5" off the panel? I want to have a "stepdown" look to the panel if it's possible. I hope you can make sense of what I'm saying. Also, from the drawing you put on here, would it be okay to move the tweeter more forward and the woofer backward? basically put it in the same line but have the woofer low left and the tweet high right? Yet again, I hope that makes sense.

I've got to go get a respirator... that mdf and fiberglass dust is gonna end up hurtin me... later dave!

So, you are wanting the woofer to intrude more deeply into the cabin (4-5 inches) than the tweeter (1-2 inches)? Won't be necessary, if I am understnding you to be saying...

I'd really like to see you keep more "tipped", array-wise, rather than vertical. If you can keep the woofer and mid from firing directly into the seat, and sucking up a grand portion of their output, I think you'll be OK, tipping the other direction, or moving toward a "vertical" line... In fact, thinking about it again, it might be even a little bit better, as the path lengths will be closer to each other in length... Equal path lengths, goooood!

Keep em out of the seat, and I think you'll be OK...

Actually I have been on vacation (last week) and my EMR blew up today, so I wasn't able to check in very much... I'll be deciding on amplifier assignments probably tonight! ;) Didja get your subs, yet? (NM... you said you were going to order those later...)

I promise they will deffinetly not be firing into the seats! Might as well stick with the MA if I was gonna do that! hahaha! I pulled out the molds at work yesterday and the speakers are going to fit. I tried making some rings today with my rotory tool ( didn't work I need a router!) so I've hit another little set back, but it'll get taken care of.  

Mmmmm... Vacation! I wish I had the time built up at work to take one. I've got to wait til july for my week off.... been thinking about going to vegas... but I'm sure theres way too much to get a 22yr old in trouble there! hahaha

EMR blew up? that's no good! I take it you are in the medical field?

ya, If the bills allow it I'm going to order the daytons on the last day of the month (payday!). Do you think If I called up parts express and played the "whats the best you can do on those" game they would budge any? lol! thanks dave!

Sa-WHEET! I'll plug the numbers into JBL tonight, as well as complete the formulation of our plan of attack! Post the published parameters (they should be on a paper with the woofers) as many of them as you have - the more you can provide, the more predictable the results! Also, give me an idea of the volume you want to "spend" for your enclosures... That'll be better than me "chasing". Knowing what exactly you can spare as far as volume is concerned will let me work with that!

Sing as you are heading toward SQ in the doors, are you wanting a similar type of response for the subs, as well?

are you wanting the parameters from the daytons only or on all the speakers???

I'm in a '97 tahoe 4 door so I can spare tons of room for a pair of 12's... Yes, I would love to keep the SQ side of the subs, but I'm not going to lie, I love feeling those lows in my chest! I like LOUD and CLEAN!!!

I do haul around a 4 10" bass cab every once in awhile so I could give up to 6 cuft for an enclosure. I'd go a little more if need be, but I'd prefer somewhere from 4-6cuft. I'll work on getting those numbers up, I just didn't know If you wanted just the subs, or all the speakers I've obtained!

thanks bro!

OK... Here's what I've got. I've double checked these numbers, too... I like!

You said you had volume to spare, and these'll love it if you can give 'em as much space as you have!

These are a WAY sealed woofer...

Anywhere between .9 and 3.3 cubic feet, with heavy stuffing (defined as .5 pounds per cubic foot) will give VERY good response and output to well below 30Hz (in car). Three cubes sealed will give you an enclosure resonance of 30Hz, and 10mS worst case group delay. (20Hz is about a 7mS group delay - thaz niieze) SWEET! I'm also seeing a thermally limited output of 119dB for one, 125dB for two 12's @ 400 watts each, RMS! With cabin gain, I expect you'll be able to see 108+ at 20Hz.

I located the papers that came with the subs.... the only thing they sent was a billing sheet.... didn't have any parameters with them at all, so I guess we can rely on daytons website. I've allowed for .12 cuft for sub displacement and will build each chamber to 3.45cuft. This things gonna be unreal!!! I'm going to my dad's sunday to route new rings and whatnot...

ive followed the posts,and for less than 50 bucks the tang bands really impress me with i think 13mm of excursion in a 6.5. i think im going to get some now also..correct me if im wrong is a .707 qtc supposed to be the flattest response you can get and for sq isnt that what you are after just wondering.





Posted By: haemphyst

Yepper... I love those Tang-Bands! If you can get 'em into a door (They're REALLY deep) they are a super driver for the money. I DIDN'T say they were the best thing going out there, but I did specify "for the money"... <grin>

.5 is "transient perfect"
.707 is "max flat"
1.1 is "max power"

A Q.5 will tend to sound "lean" to many people, but to me, I simply LOVE the ver slow roll-off provided, and I recommended this alignment for him, as we will be actively crossing his system over, and he will be able to adjust the output of the woofers, specifically, while maintaining extension, and response capabilites. The curves look nice, too! posted_image

A Q.707 provides for the OVERALL flattest response, at the MINOR expense of transient capability and extension.

A Q1.1 is the "humpy" or occasionally "peaky" sound, providing the least extension, but best overall output, and best power handling - i.e. "you can beat the CRAP out of 'em". Most manufaturers products found in the "Big Box Stores" are aimed toward the 1.1 end of the spectrum, if in a sealed alignment.

I took the daytons and stuck them in a prefab suv box so I could hear them. I have to say I'm freakin impressed by 'em and cant wait to get that huge ass enclosure built so they'll really drop! I think they're in a little over 1cuft each right now... I cant even imagine what the 3.3 is going to sound like! I've got them wired on a kenwood amp with about 300 rms to each sub... I'm going to wire in the HK1000D and see where that takes 'em!

What happens to the power handling with that big a box? I like the low frequency response of a large box too, but I've gone too big and over-powered the subs in times past. The good thing about too big is you can always add some Styrofoam or something to make it smaller!

I got some progress on the door pods done. I got the tweeter and mid rings mounted and wraped to take care of sealing them. after a couple layers of glass I'll mount the 6.5 ring and wrap the pods again. After everything is cured and ready for paint I'll cut the back for the TB and the rest will stay sealed. I'll post pics on fiberglassforum tonight.

Subs set around 50-80, as steep as possible (hopefully at LEAST 24dB). Kinda what I had in mind for the doors was 50/80-200 (maybe 300), 200/300 to 3500, and 3500 and up. The Silver Flutes will be handling the brunt of the load, but I think they're up to it. If I can run my 4 inch Vifas (20 watt power handling with 165 watts on tap) on that same range, the 'Flutes'll do just fine. I know you are aiming specifically at SQ, so I'm not terribly worried about compromising output. I am worried about sound power.

I get PLENTY loud, and I think you will as well.

I can't find anything on the 'net regarding the actual settings on that crossover. I can BUY a manual from Audiocontrol, for $11.00, but I'm not gonna... posted_image

I'd like to see (...and I am assuming that you are dedicating the 4xs to the doors) the PFM set to the same frequency as your sub (To be determined, but 90Hz seems a little bit too high, to me. Aim closer to the 50 to 65Hz range) around 250 to 300 for the mid-bass/mid transition, and 3500-4000 for the mid/tweeter transition.

I printed off a 4XS manual and did some reading. The modules are preset, but they say they can be programed. Is this something I can do or do I need to find someone to do this for me??? I'm a little lost on this one...

the manual also stated that there are two 3.5kHz, a 90Hz programmable crossover module, a one 33Hz programmable Frequency Match module, and of course the 90hz sub.

I was able to find the manual online as well... Using 14 pin DIP headers, you can build any frequency module you want. Headers can be had all day long for 50 cents a piece, and resistors are a dime a dozen, almost literally - even 5%-ers.

To figure the resistor value, divide 7200 by the desired frequency, and this will give you the value for the needed resistor.

7200 / 60 = 12.5K ohms (This is the PFM)
7200 / 250 = 28.8K ohms (30K is more available, and would be 300Hz)
7200 / 3500 = 2.05K ohms (2K is FAR more available, and close enough...) You already HAVE these, or should still have them... Saves you the work!

The modules are CAKE to build. You simply solder the resistors ACROSS the DIP header, 6 each, leaving the middle pair of pins open.

2 headers, 12 resistors, and 10 minutes with a soldering iron, you're done! BTW, if you cannot find an exact resistor value, divide 7200 by the AVAILABLE value, and this will tell you the frequency you will achieve.

Example: 7200 / 2000 (2K ohms) = 3600Hz

Because no audio signal actually travels in or through these resistors, Vishay or some other high-dollar exotica isn't necessary, but the tighter you can get, TOLERANCE-wise, the better off you're going to be. I recommend 5% or better. (Resistors come in 20%, 10%, 5%, 2.5%, 1%, and precision. The lower the number, the tighter the tolerance, and the more expensive they will be.) Carbon pile (less expensive, more available, and generally can be higher precision) or wire-wound, 1/4 watt, is all you need.

Industry standards resistor decades. That chart will tell you EXACTLY what resistors you will be able to lay hands upon... Additional information, for those interested.

(I am on lunch, sitting in my car... I HOPE you end up with (at least CLOSE to) what I have, or at a minimum, something that you will be happy with. Gawd, I love the sound of my stereo... I feel like Rick Davies is standing right in front of me.)

i pulled the DIP headers off the green board and found there was a little slip of paper underneath each one and the sub had 70hz under it. the other two had 150hz. There are no resistors on top of the PFM. it's a white rectangle with 90 hz written on it. is that where I'm going to need to build a DIP for it? I need to take a picture of this and draw on it for you, so I can understand this better. I've been working all day and the hampster in my mind has slowed the wheel down big time lol!

I was on lunch today sitting in my truck trying to learn my radio's eq to some dj shadow.... I had never heard of Rick Davies, so I did a search on him and ran across a guy named Robert Rich.... very good stuff!!!

Im sure my truck will sound absolutely wonderful, but I think it's going to take me learning a lot more and investing in some better amps before I need to try and come knock on your door lol! But hey, maybe someday!

By the way..... I think I've decided on a PDX1.1000 and two of the PDX4.100 or 150. I'd really like to run eclipse amps, but I just can't find one that matches the eclipse 4ch I have that provides enough power lol! I want my amps to match so bad lol!!!

That's the same amp compliment I am using... Very sweet sounding stuff. A single 1.1000 and a pair of 4.150's, one bridged to the mid-bass. You might consider a 1.1000, a 2.150, and a 4.100. STILL a ton of power, and you'll be able to save a few bennies, too. 1700 watts RMS... Geez. posted_image I thought *I* was the only insane man round about these parts! (With a proper nod in the direction of Mr. SPL himself, of course...)

As far as the present PFM, it's "potted". The resistors are inside, and the case is filled with plastic.

Rick Davies is the lead singer for one of the finest (IMO) rock and roll bands of my generation - Supertramp. I have every studio album they have ever released, and even one or two that they DIDN'T! Now, Robert Rich is the guy *I've* never heard of! :)

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Less riff raff, more building! I hope you finish soon so you can let us know if you like it or not. I have a build for myself that is waiting on your results!

And Supertramp is not bad at all by the way.

Strange you should mention THAT album, as that was the one I was listening to! (The very rare MFSL version... HIGHLY recommended! Some say there isn't any difference, but believe me, there is! Last one saw on eBay, I think it was $100.00 posted_image )

That's the same amp compliment I am using... Very sweet sounding stuff. A single 1.1000 and a pair of 4.150's, one bridged to the mid-bass. You might consider a 1.1000, a 2.150, and a 4.100. STILL a ton of power, and you'll be able to save a few bennies, too. 1700 watts RMS... Geez. posted_image I thought *I* was the only insane man round about these parts! (With a proper nod in the direction of Mr. SPL himself, of course...)

As far as the present PFM, it's "potted". The resistors are inside, and the case is filled with plastic.

I wont lie, I have seen where you have stood up for the PDX amp's, so that's been a major factor into the choice, but I've also read many others comments about the amps, and I think they would satisfy me.

since I was 14 (now a whopping 22) I've made just a ton of noise and tried to run as much power as possible and still never really acomplished anything with it. I'm a musician (been playing guitar and bass since I was 9) and it just occured to me one day "if you like music so much, why the hell cant you understand what youre listening too???" and that's where my love of having power to spare and my want of an SQ vehicle came along. I just want clean power now and realize that you get what you pay for...

I had never heard of Robert Rich before either, I just ran across his name and heard some very good nature sounds mixed with electronics (i do enjoy a good dj.) I had heard of supertramp but never gotten to listen to them, so I looked them up. IM HOOKED! I heard so much zeppelin in the song school, but then the other songs just took me on a loop! The last band I played with we covered most of the thriller album, talking heads, rick james, any zeppelin, and a bunch of other stuff, and I can't believe I've never heard Supertramp before.

As far as the potted PFM, do I change that or leave it...I'm a bit confused on that subject.

Thanks,
Adam

Well more seriously now, I really enjoy reading your progress here. So keep up the good work! I look forward to what comes next.

And thanks for mentioning MFSL, I've been looking for something like that for a while now. It's difficult to find productions with decent dynamic range : /

I'd say build a new PFM. 90Hz is just too high. Really, since this is going to determine how low your doors go, I'd like to see a lower frequency.

I was about 25 when I "reformed", so you're well ahead of my curve! posted_image. I was a true bass-head, and I wanted it as LOUD as I could stand... I wanted to shake the rafters of the install bay where I worked. (And I did, BTW...) I was the first guy I ever knew with eight 8's. The same Civic that eventually had two Infinity 12's in TL... (I was the first guy I ever knew with a TL in his car, too... See a pattern here? posted_image ) I ran an Orion Red 50, bridged... Radio Shack 8's. Yes, 'Shack... Those things would flat GET IT! Actually a really nice woofer, sourced from KSC, the same manufacturer my 18" TLs still use. I have no idea of the availabilty of the drivers anymore, but for the money, AND the time, they were decent drivers. I wanna say I paid 20 bucks each...?

Huh... a new 'Tramp 'vert, eh? I highly recommend "Some Things Never Change", but later. "Crime", and "Quietest Moments" are my favorites, alongside that one, and I think you should CERTAINLY have those to listen to. Both are fantastic recordings, especially for their day, and go with me, pretty much, wherever I go. While the whole catalog is FANTASTIC, I (as big a fan as I am...) don't think they are a really good "live" band, but I'm not really a fan of anything live. Super classic rock, and "must haves"!

I just looked on eBay again... Holy gold pressings, Batman! As much as 700 dollars for a sealed "Crime". I saw 400 for OPENED ones!

Thanks, it's been a huge learning experience for me in two different fields. Not only is this my first SQ build, But it's also my first REAL fiberglass project (I've worked with the materials several different times doing very small scale things, but nothing to this size.) I'm ready to get them installed and hear everything come to life!

I will build new ones then. I thing it will be simple enough. I just have to order the parts now.

Not related to Supertramp, but I saw a sealed Mystery Science Theater 3000 "The Movie"  (if your into that kinda stuff) on ebay for $200 one time.... I spent $60 on the opened one that had the movie store sticker ripped off the box lol! What can I say, I'm addicted to cheesy films being ripped on!

**** UPDATES****

This is what they WOULD HAVE looked like if they had FIT!!!! I stuck the pod on the panel with a couple screws to do a test fit to see what I needed to trim, and something told me to put the panel back on the door to make sure everything cleared before I glassed the top piece. AM I GLAD I DID!!! The sub hit the floor and the door wouldn't close the last 8 inches..... needless to say they don't look the same anymore lol! I'm thinking about moding the base mold to come up where the stock tweeter goes, and put the vifa there so I can bring the Silver flute higher and more forward, and do the same with the Tang Band.

I wanted those to work out so bad. They were going to end up looking killer IMO. Oh well... Just means I was meant to build something cooler lol!

On A side note, Should the rings have had more angle to them for SQ purposes????

So I took the rest of my day off to wire my truck up for this build.... Heres some pics!!!

posted_image

This is the nightmare the last shop left for me to find underneath the carpet.... off to a GREAT start! (sarcastic as hell!!!)

posted_image

This is where I pulled the 0ga. please notice the gromet I used next to the hole where the previous shop had just drilled a hole and pulled 8ga through with nothing used to protect the wire!

posted_image

I pulled wire for the 3speakers through the sleeve in the door jam. Thank god there was no molex!

posted_image

other side done.

posted_image

This wasn't 5 minutes into starting the wiring... Don't you love putting your hands inside doors???

posted_image

This is MOST of what I pulled out that DIDN'T Go back in! There was so much crap!

There is now a single strand of 0ga running down the passenger side to a distribution block where I've got 4 ga running to my 2 amps (there is going to be a 3rd amp added when I get the pod situation fixed.) I have seperate grounds for the amps. Down the drivers side I ran my RCA's along with 6 sets of 14ga speaker wire (I didn't use ANY factory wiring for this!) The RCA's were fed into my 4XS (that things pretty damn cool!)

I have no more alternator whine, my system no longer makes a loud THUMP when the truck is cranked, and I know I feel better knowing that I did it!  

So that was today for me. I didn't get finished by any means. I still have to put little trim pieces back on and clean up the wiring a little more. I just plan ran out of time today.

I'll be making new speaker rings this weekend when I'm home at my parents so I can start over on the pods = ( !

Oh, and in answer to your question, I think that angle will be adequate. The bands you will be running should be well within the 45 degree output plot of them, so really only a little bit of angle is necessary.

I do feel for ya, though... doing all the work, THEN discovering something doesn't quite fit the way you wanted it to... Yeah, it sux.

Cool. I'll keep the same angles on the new pod's then.

I'm just glad I didn't waste all that fiberglass on the top, THEN find out it wasn't going to work. I'll make something work

off to think

 I feel ya too . I built a wall in my 1993 sentra years back for 8 15 inch subs got it nearly done test fitted the subs and the 2 in the middle the magnets hit forcing me to start over. The second designed turned out looking better so it was worth it .  good luck to you
