Printer Friendly Forum Posts - high spl 15" for good price

Hi, I currently am running two Soundstream 15" with an SPL 1440 amp in a custom sealed box with no divider. I currently hit 140db (verified at Kumho StreetWarriorz sound competition.) I'm trying to up that to around 150-155ish w/o draining my wallet. Since you guys are really the only people who know what the hell their talking about, I was curious on how the Power Acoustik Fubr-15's are? Or if you know of any other speakers that would be good, but aren't like 300 dollars a piece.

well you aren't gonna win any sound comps with a sealed box...you can use WinISD to model different enclosures and see what their response curves are.

What model 15's do you have??

They're the tarantula series..only not thwe new ones, they are rated at 450rms.

The reason I went with a sealed box instead of a ported box, is because I wanted as good as a response as I could get with 15's.

Well you really need a nice ported box if you want higher numbers

yeah...maybe later...but I'm more curious on the subs than box for now, I just want peoples opinion on the Power Acoustik Fubr-15's if anyone has heard them or had them before, or if they have other recommendations. Also, what about the powerbass xtreme 3xL series (https://www.powerbassusa.com/products/subwoofers/3xl_subwoofers.html)
I have their 2xl coaxial speakers, and they are pretty good speakers, especially for the price.

What Kuhmo show did you go to? very good possibility I was the judge for the show.

Like the other have said your best bet is to build a ported box.

Right now you cat beat the 12" kicker L7's hands down...the 15s arnt as great for SPL use

If you upgraded your amp and put your aubs in a ported box you could possibly get to the high 140's

the 150s are a very high score espicially for a stock class.

But 2 12L7s with about 2500WRMS will do a 150 in about any vehicle with the correctly built ported enclosure

It was the one at Milan Dragway in Michigan. I have a 93 plymouth laser (same as the eclipse) with a custom made box that takes up the whole hatch. Being the first box I made, sealed seemed the way to go, plus as I mentioned earlier, I wanted good response on 15's. Another benefit of the sealed box was the space issue, Id be closer to the recommended enclosure size with a sealed box as apposed to the ported one.

I've also heard some stuff about audiopipe.. I've never heard them, but I've seen them up hand, and they look like their good quality. https://www.audiopipe.com/AudioPipeCatalogOne.asp?Picture=AP-26.jpg

Someone told me that they just set some Db record, but I'm not sure if he was just blowing that out his ass.

blowing alot of Smoke out of his @ss

The major companys are the way to go

Kicker
Digital Designs
Rockford
Db Drive (They are really starting to shine in competitions)
American Bass (High end only)

In both USACi and Db Drag Kicker has the largest # of placing competitiors at both of thier world finals

I know usaci kicker had over 30 competitors place in the top 3 of thier class

I would work with what you have currently. Untill you find the peak of that setup its not worth upgrading, except the amp...you could use alot more power

I would recommend a box that is roughly 3-3.25 cu ft ported and tuned to 45hz

I know those cars are capable of over a 150...but the loudest I have seen them go is about a 153...That was using 2 12" Kicker L7s and an Incriminator Audio 20.1 for the amp

I know I will be doing the milan event this year, I want there last year as I was out at another show

The show will be june the 9th this year. If you remember at that time ask me for some tips then, on whatever you have at the time

sweet thanks a a lot.. I'll look for you

I have a part sponsor with a local company that I can get the kicker cvr15's for $85, but I was told they suck, and the cvr12's are the only good cvr's. He told me to go with the cvx15's. Would you recommend that, or just a more powerful amp?

the fubers suck, my friend had two and was hitting the same as me (with a cheap walmart meter lol) they didnt sound good and he had them in a sealed box. those DSM (you should know what this means being an owner of one) can make subs really LOUD!!!!!! i had two cheap pyramids in a common chamber box and it wasnt bad for $200 (subs and amp lol).... but yeah my rockfords could hit as loud as my friends fubers.

If you can get a good deal on kicker product you cant beat the L5's and L7 12"s with the power you currently have I would go with the l5's

put them in a 2.75 cu ft box with 2 4" aero ports that are roughly 14 inches long.

That should get you very very close to the 10 mark your looking for

add more power and it should get you over a 150 easily

Well, I already have one 12" L5 just cause I install radios, speakers, whatever almost every week in different peoples cars, and have acquired one in a trade. It's just that I put a lot of time in making this box that takes up my hatch, and having the Soundstreams at the time, cut to fit for 15" circles... so thats why I want to stay with round 15's. The power acoustik and audio pipe just have 15" subs that are around what I'm looking to spend. I know to go big, you need to spend big, but I just want to be able to spend a little, but hold my own at a comp, while still maintaining clarity and response for daily driving. Thats also why I was thinking the kicker crv15's, or crx15's. Obviously the crx's are better, but are the crv's that bad?

I hate double posting, but I've hooked up some Audiobahns, and think they sound pretty good for the money. What about their AW1500V or AW1500N?

no, audiobahn will sound like poop in a hatch, and will suck or blow at competitions

I know I sound like a noob, but I guess I am at this stuff..my first subs were from ma audio... I know this board generally looks down on MA, but what about two MA1500XL's

no, ma audio is low quality.

I have already told you the brands to look into if you are planing to compete and use the product as a daily driver as well

You will not be capable of over 150db with Audiopipe, audiobahn, ma audio and other low line brands with a stock style setup

If you really want to hang with the guys at shows I have already put it out there. (2) 2006 Kicker L5s with about 2500watts Rms will do roughly a 153 with the right enclosure in that car

box of about 2.75cu ft internal with 2 4 inch aero ports with 14 inches of length.

That is an SPL box only, it would cause alot of damage to try and run that box with normal music.

I know you dont want to rebuild your box but that should be the least of your worrys, a sheet of wood is $22 the equipment will cost most of the money, then it is all about haveing a setup designed for street and a setup for SPL

engineer a proper enclosure and its guaranteed to yield incredible spl

Jeff.. its not a kicker L5...but have you heard anything about them?

Havent played with them, but I have been tempted...I have 2 much kicker equipment that I have collected to switch brands for competiton now.

I have said it before and will say it again, when it comes to competiton use, espically for any of the street or stock classes...The Kicker L5's and L7s Cannot and will nto be beat

I was running aginst Digital Designs 9915's and I beat that car with my little 10L7's The Truck that did beat me at finals was using (3) Digital Desigans 9917's with close to 30,000 of power

He had me on both power and cone size

yea I know kicker... I'm thinking about cutting my box to fit 15" squares and buying two 15" l5's... or I may just buy some l5's or l7's as 12's with a box, and just ditch my old box, and not buy a system for my other car, but just make it easy to transfer the subs and amp.

You are talking about two COMPLETELY different Hondas..

yea I know... I meant to say cvr and and cvx, don't know what I was thinking.

how much power does your amp make?

have you been to any shops to listen to anything 1st hand?
most shops have installed their woofers in various configs and can tell you what will get loud in your car.

-------------

I do all my wiring, and I know about the various configs, the speakers had two 4 ohm voice coils, so I ran those in parallel, making each speaker 2 ohms. Since my amp isn't 1 ohm stable, I didn't bridge it, and ran each speaker to each output. The amp puts out about 360 watts at each channel when run at 2 ohms. So thats all good.

Anyways, I talked to my guy last night, and he said he's getting in a shipment of the '07 15" JBL GTO150. He said that their only rated at 300rms, but that their way underrated, and that a 2000w class D mono amp will really push them. I just don't think that they will really be a step up from what I have though.

If you don't want to spend too much money and you want to use the same sealed enclosure I'd recommend the fi Q15

https://ssl.perfora.net/www.ficaraudio.com/sess/utn;jsessionid=1545b2b7f7d0b58/shopdata/0020_Q/product_overview.shopscript

He does not have enough power for a Q...and also, whatever you go with, do yourself a big favor and build a custom ported box...

Blowing up in a car accident doesnt worry me, as long as I'm putting out some major dB's when I die...

If the woofers are in a common chamber, i would most definitely bridge the amp

-------------

What about two kicker S15L5's? With my sealed box what do you think they would put out? about 145db? Also I received my new radio, its a Sony CDX-R5515X. For some reason though, It shuts off when I turn the volume up. Is there some kind of db cut off, or are my power wires too small or something? I never had that problem with any of my other head units.

its sony....... have never had that problem with sony but have had others.

Just because Sony doesn't make the best speakers, subs, or amps, doesn't mean they have bad cd players. I have tried multiple brands, and have found Sony to be one of the clearest, while still mixing in highs, mids, and lows with little to no distortion. Also you can't be their clarity and sn ratio for the price.

I dont like the 15 L7's for some reason they just dont handle like the 10's or 12's int he competiton lanes, They actually do worse then the 12's or 10's from my testing, they take to big of a box to get loud, and dont handle the power as efficently as he 10's or 12's

With the CD player I would check your ground

Alright, so I guess I'll just get rid of my box, and get two 06 L5's in a ported box?

So now I need an amp...lol just kidding, I'll figure this out on my own, thanks for the help.

Wait, factory certified refurbs for '02 models are $100, and new 06 models are $125. Are the '06 models a lot better than the '02 models? Or did the remain the same throughout the years?

Yes, they are much better...espically the L5's and L7 of 06

The 06 L5's are almost Identical to the 04-05 L7's

OK. Stay away from refurbished 06's? Or are they 'good as new'?

The refurbed 06s will be good a new, I actually had beet luck with the refurbed 04-05 when I used to order them, they were actually a little stronger then the factory ones, dont quite know why

But I would highly highly reccomend the 06 model subs

Figured out the cd player issue. It's how the front speakers are wired. The dash speakers are wired to the door speakers in parallel from the factory. The new radio probably can't handle the low ohms (not really low, but you know). I figured this out by fading the speakers all the way to the rear where there is just one speaker per channel, and it didn't cut out. So the leaves me a couple options.

Fade all the way to rear when in competitions
Unplug my two dash speakers when in competition, or wire them to a relay where I can switch them on and off.
Rewire the speakers in a series connection instead of parallel.

I'm thinking of the last one, but I wanted to know is if this new higher ohm setup would make those speakers noticeably quieter? And if so, how much?

Also Jeff, what do you recommend for rms wattage for the two? 1500w at 1 ohm in a ported kicker spec box get me around 148-150db?

More then Likely I would reccomend something you can wire down for comp use only. It all depends on what amps you decide on, The KX1200.1's will take a 1/2 ohm strapped for a burp...and you should get 3000+ watts out of a pair at 1/2 strapped

You are going to need to rebuild your box to get over 150!

I'll be getting a new box. The subs are the 4 ohms, not the 2, so I wont be getting a 1/2 ohm setup. The 1200.1 puts out 1200@1 (obviously you know that). But if I don't go name brand theres SPL (just bought by pioneer so quality should go up, not like it was terribly bad before) with their Z1X2400D which puts out 1800w rms at 1 ohm. My amp now is SPL and I don't see a problem with it. Also Hifonics Brutus BXi1606D puts out 1600w rms at 1 ohm and the cheaper BXi1206D does 1200w rms at 1 ohm. Another thing I was considering was maybe 2 low class high power amps, so even hen they aren't putting out what they say..their still putting out. Two soundstorm 2500 mono's put out 1500w rms at 2 ohms. So that would be like 1000w to each sub? Also, their only $110 a piece.

The Z1X3000d is actually A pretty strong amp, I tried one just for fun becasue I have a friend who owns a show and carrys them....with constant voltage put to them they are capable of close to 2700 Watts
