I'm looking for 8" drivers that will install into an '05 Mustang (default location). Any thoughts on manufacturers? ------------- Squirrel

[/QUOTE] Slight difference. [/QUOTE] ahhhhh yes my bad, it can do it all though. its a really nice subwoofer/midbass driver. your getting the best of both worlds. and if its in a factory location your set, no need to take up space in your trunk. if this makes no sense im sorry

*laughing* It makes sense, but I get all the bass I need right now from my 2 RF Punch HX2's in the rear. I've got (2) 5.25" Infinity Kappa 50.5cs's for the front and (2) 5x7" Infinity Kappa 572.5cf's for the parcel shelf.

I follow, but it is best to have a driver designated for a certain frequency ranges, due to proper enclosure sizing, amp settings. I don't think that sub will have much authority above 70-80 hertz in any enclosure, but anything below just fine. wv, do you paln on runing an active system? Any other drivers like a four and a tweet? or just a 8" and a tweeter? -------------

you dont get enought bass form your 5x7's? or you want your midbass more defined? or you just want to fill the hole? which is it?

I'm still running stock while I get my components together. Most have come from previous installations I did in my '97 Explorer and '02 Mustang.
Here's everything I've got right now:
(1) Alpine CDA-7995 headunit
(2) 5.25" Infinity Kappa 50.5cs's
(2) 1" Infity Kappa dome tweeters (part of the 50.5cs component set)
(2) Infinity external passive crossovers (part of the 50.5cs component set)
(2) 5x7" Infinity Kappa 572.5cf's
(2) Kenwood KAC-649S amps running the Infinity's
(2) Rockford Fosgate RFD2112 Punch HX2's
(1) Rockford Fosgate Power 1000bd mono amp running the HX2's
(1) Sealed enclosure (dual chamber) at 1.25 cu.ft. per chamber
(1) Rockford Fosgate 1-farad cap
(1) Lightening Audio ANL in-line fuse (accepts 1/0-guage input)
(1) Lightening Audio AGU fused distribution block (accepts 1/0 guage input)
(1) Rockford Fosgate AGU fused distribution block (accepts 4-guage input)
(1) Rockford Fosgate non-fused distribution block (ground distribution)
(1) Stinger relay (for when I ran dual battery setups)
The setup I ran before was as follows:
- The Alpine headunit has no pre-outs. Everything is straight low level innerconnects to the 3 amps.
- Active high and low crossovers were used through the headunit (although I can't recall what I had them set at)
- The 2 Kenwood amps run the Infinity's. Each Kenwood amp is 4-channel (I know, but it's all I could afford at the time).
- The first Kenwood amp is bridged to 2 channels, running the Front left and right Infinity Kappa 50.5cs components at a 4ohm load per channel (the 5.25" and 1" run through the external passive crossover).
- The second Kenwood amp is bridged to 2 channels, running the Rear left and right Infinity Kappa 572.5cf's coaxials at a 4ohm load per channel.
- The Rockford Fosgate mono amp runs the 2 Punch HX2's (2ohm DVC's) at a 2ohm load.
- The cap is isolated to the Rockford amp for voltage regulation.
I've run this setup since '03 and have been extremely pleased in all aspects (lows, mids, and highs).
At the time I ran 4-guage from the battery through an inline AGU fuse to the AGU fused distro. From there I ran (2) 8-guage splits to the Kenwood amps (1 8-guage per amp) and (2) 8-guage splits to the Rockford amp (1 straight to it, the other connected the cap to it, making a combined 4-guage input). I know I should have used either a single 1/0-guage or (2) 4-guage lines from the battery due to the power consumption, but at that time I used what I had and it was hard as hell to find 1/0 components. Now I have an inline ANL fuse that will accept 1/0, as well as a new AGU fused distro block that accepts 1/0. So it will be a single 1/0 line from the battery (as well as 1/0 from the alternator to the battery).
The midbass is something new that I thought I'd experiment with over time, especially since the factory Shaker 500 system was nice enough to provide me with mount points for (2) 8" midbass drivers. So basically it's just to fill in the hole, but I would like to see what it adds to the overall sound. ------------- Squirrel

if i had 2 8" openings factory i would put 2 of the tc-1000's. they have a 48xmax which is crazy and the 8 can handle it. but like Dwarren said i dont know how high of a frequency it can go in that opening. if the box is right they will impress.

Hey, good to see you again squirrel, Sounds like you are putting together a nice system, I have not used 8's in years so I can't reccomend any but many years ago I used Alpine 8's as subs which I glassed into the back of a porsche 911. everyone who heard it asked "where are you hiding the 15's" so yes, it is possible to get sub from an 8. Of course this was in a perfect enclosure, and these were serious and expensive speakers but unless you can build a sub enclosure into the door ,mid bass is all you can expect. (don't forget lots of sound deadner) Just remember if the amp does not have a band pass cross over you will need to build them yourself or purchase them. real good professional passive band pass cross-overs are expensive but if done right it can fill the "hole" that most systems have in the mid bass frequencies. of course there are many other factors that will effect the sound but nothing ventured, nothing gained.

I forgot that there are active crossovers that will do what you need. Did you have one of those because a good one will really allow you to dial it in without having to try all different value components if using passives. -------------

Thx everybody. It will be a while before I decide on anything so I still have some time.
As for the crossovers, I plan on trying passive crossovers first, budget restricted and all.
Thx again ------------- Squirrel

If you add a dedicated amplifier for the 8's, you could bandpass them using the amp's active crossovers. Then set the highpass on your mids/highs amp to a higher setting. For midbass woofers, you could use a variety of drivers including those that are made for home use at 8 ohm impedance. Look at Madisound for a great selection, and particularly at the closeouts (where I always look first). As dwarren suggested, and would probably be ayed by one haemphyst on this forum, Morel is a quality driver for the application. But you could use a variety, and looking through Madisounds lineup will acquaint you with some good ones. Since your range for these will be limited bandpass, you should build an enclosure for them, I believe, instead of using them IB in the doors. This is a tip I heard from kfr01 on here some months back, as he said he found that he could achieve more reliable response and sharper impact that way (or words to that effect, IIRC). Your system will be extremely defined by frequency range when you add these components to the mix, so dialing in the crossover settings on the amplifiers will be a critical part of the job. ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

They do make 8's that are specifically geared to sub as well as ones that are geared for midbass. However it depends on the frequency response of the specific 8. Now if the response is lets say 40hz to 2000hz (this is just an example, don't know if any 8's have this specific rating) it could be used as a sub OR a midbass since there is enough frequency response available for either.. Since you are looking for midbass in the doors and not a sub I would start at 100hz on the low side and dial in the high cutoff in by ear, using different value components. (shoot for 250-300hz and adjust from there) stevdart has a good point that even though you are not looking for sub an enclosure will give much "tighter" results, better sq. If you use passives you will also need to decide on a slope, the steeper the slope the more components and money you will need. I think you will be better off with an electronic cross over w/ bandpass and dedicated amp or using an amp with a built in band pass cross over if you can find one. With what you are trying to accomplish if the crossover points are not right it will probably do more harm to the sound quality then good. Keep us posted on how its going, appears like this system should be killer. -------------

That's not necessarily true. The drivers in my home audio speakers produce frequencies from 25 Hz all the way up to 2.8 kHz. And they do it flawlessly. It all depends on the design.
If you don't mind going with some 7" drivers instead, here's some really good suggestions:
For 8 ohms: https://www.adireaudio.com/Home/ExtremisMidwoofers.htm (these are the one's used in my home speakers mentioned above)
For 4 ohms: https://www.mpyreaudio.com/65m0.htm

steven, it does not matter that your 8's can do this. As long as nouseforname says thay can't, then all facts, credentials and personal first hand experience are thrown out the window. He will try to make you feel like you are dumb, but since you know from personal experience that you are right and it is not debatible, in a sense he will call you a liar. But I agree with you 100% because facts are facts and truth is truth. Although some try to warp it, it is futile in the longrun. The problem is that other less experienced people may be getting the wrong info or not knowing who to believe, further adding to thier confusion. But this is the price we must pay to live in a free country and post on a public forum. I wouldn't have it any other way peace -------------

Hmmm...I guess if I used an 8'' with a frequency response of 30hz -100hz. I could certainly expect loss of reproduction quality within the mid bass frequencies . Anyone know where I could find such an 8'' ?

Can you provide more information on what you are looking for? Many 8's will handle those frequencies you specify without a problem, with different results. Some, like the smaller drivers I linked above will handle it with no loss in midbass reproduction if installed properly.
I really suggest checking out the Extremis link as there is a plethera of technical information on there about the driver. If you have any questions about reading any of the graphs, or on what something means, please feel free to ask on the forum or PM me.

If you are posting to me steven I was being sarcastic because "someone" posted- "a speaker designed for sub bass will not acurately produce anything in the midbass frequency range." The topic is about 8's so I was "wondering" where I can find an 8 that ONLY produces sub frequencies and not play accuarate midbass. It was a joke, but obviously not funny...oh well. Maybe it will be now that I explained? But I did check out some of the links you left as I have not used 8's in so long I was curious what they can do these days and the companies that offer them. I have had good results with 8's in the past used as subs OR midbass, depends on the enclosure, cross over and of course frequency response.. Thanks. and squirell, if you don't make up your mind you will never get that system bumping. I would try something different and whacky and see what happens. -------------

I agree with Steven (surprise surprise) that the Extremis is one of the best woofers I have ever used. I currently use four of them in my home theater and have heard excellent applications in vehicles. FYI, the "mid bass" region is generally the two octaves from about 100Hz to about 400Hz. Almost any woofer I know about, including most subs, will "play" this band, although speakers designed for it will sound better and be more efficient doing so. ------------- Support the12volt.com

Indeed, Bob! These things are the most incredible mid-bass drivers I've ever put in my doors... A Morel fan from WAY back, these things kick the Morels in the dirt... 2 notes WELL worth the expenditure. ------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice.
