Don't forget Dynaudio. I'm a big fan of their stuff. Eton also has some stellar stuff.

Cebby:

You got good taste in speakers

The old Diamond Audio Hex series was made by Eaton and at every competition I went to they just sounded great, and Dynaudio is simply amazing stuff. If and when I decide to upgrade from my Focal Polykevs I would love to get a Dynaudio System 340, Focal Utopia, or the Seas Excel.

Cebby

Obviously you also shop here like I do...

trangk

Yup

I also shop at www.zalytron.com (just ordered a set of Raven ribbon tweeters).

I'm guessing your really into audio ... mind if I ask what sorta stuff you have purchased/built from madisound? You can PM me if this is getting off topic ...

Cebby

Are you putting the Raven's in your 4Runner? I thought ribbons didn't have a wide enough dispersion pattern for the confines of a car.

I've bought a few things over the years from them: Vifa tweeters and small mids, Dyn mids and mid bass, Eton mids. All I have left to put in my 4Runner is the Dyn mids (6" with a 3" VC - can you say QUICK?) Never bought any subs from them though. I used to compete in IASCA for a few years in the 90's. I had a pair of Celestion 15's that were probably the best subs I ever had (4" VC). They only made car stuff for a couple of years. I used them when I was in Pro 0-100. They hammered on a RF Punch 40 DSM bridged.

Now, I run a normal Alpine head with stock speakers. This will change over the summer though. I have 3 of the good RF Punch amps, Dyn Mids, Boston Neo tweets, Alpine 1310, a pair of Alpine 3681's and a 5957S. Fiber and digital time alignment - YEAH! Gotta figure out the low end...

What do any of you competitors think of the Sound Stream 15" SPL?

I ran one in my rig until it blew (details on my stereo page) and I replaced it with the JL W6 15" I have now.

I can send it back to them and they will fix the coil that blew (it's a duelie) and put on a new cone for about $125 or so.

what do you guys think about the JL 10w7...i dont think i need a 12 inch cause i heard the w7 series kick a$$ already...i just want some bass..not ghettofy my car

Cebby:

No, the Raven's are for home use. I am planning on rebuilding the two main speakers in my home theater setup (right now each cabinet is running 2 7" Focal Utopia with a Focal TC90 kevlar tweeter). The Raven's are going to replace the TC90.

Wow, hope you take pics of that setup. Are you planning on competing again? Would love to hear your stuff . My setup right now is an Eclipse 7002 w/Eclipse 5962, Focal 6.5 Polykev w/Vifa tweeters and custom crossovers from Madisound, Illusion Audio ND10, Zapco AG350 (2x150 for front) and a second AG350 (1x 350 for the sub), Zapco SLBTP for converting RCA to balanced input. Much more modest than your setup however.

I definately recommend the Illusion Audio sub if you want a good SQ sub.

i dont think you will get the same low tones but it will be tighter and plenty loud.

I've never heard the Sound Stream SPL series, but for what it's worth, Vifa used to make alot of the Sound Stream speakers (the SS Exact component system used the same Vifa tweeter I'm using now)

Personally, I think the $125 is a bit steep for reconditioning that sub and I'd rather run the JL

trd90toyota

I'm running a one JL 12w3 in my runner and it pounds hard. The amp I'm running is a MTX.

Cebby

More modest??? I think not. Your rig is a who's who of top SQ gear. I'll bet it sounds incredible!!. Do you have a stealth install or is everything showcased? Do you run the separates in the stock locations, or in the kickpanels? My system wants to be yours when it grows up...

My home theater is more tame than your. All Yamaha electronics, Boston powered 10 sub, and MB Quart .5's all around.

I'll have to look around, I might still have some replacement domes for the Vifa's. I'll send them to you if I do since I don't have any Vifa's anymore.

Cebby

I agree totally here. For the money, the JL's will do a better job for you.

I see everyone here is also big time into sounds.... Here are my favorite 2 system forums:

www.termpro.com

termpro is actually were the rules are discussed and whatnot for db drag - basically the official site ( and my favorite )

http://pub26.ezboard.com/bcaraudioforum87927

db don's forum - maker of the infamous and renowned Inhuman, PSI, and X-1 subs - also the first to sell quad coil subs at least in my memory.

Bumpin' Yota

That's a typical reconing fee. Im not sure if you could do that and still turn around and sell it getting your money back. That SS15 sub does have a good spl record if in the correct box. Getting scores close to 150db from one 15 off of 1000-1500 watts was not uncommon a few years back.

Bumpin' Yota

Great sub, that in the correct box will amaze you, however they are waaaaaaaay overpriced in my opinion. If you can get them for 40-60% cheaper than retail (like dealer) then go for it.

doink,
You gotta tell us what it is you want. I have 4 1200w 12's in the back of my 4Runner and it actually broke the rear view mirror once from the bass. I'm guessing you don't want that though. Mine however are for SPL, not as good on the SQ side. If I could do it again, I think I'd go with only two 12"s with good SQ. If you want sound quality, that's quite a bit different than pure SPL. JL makes good stuff (SPL and SQ), but I think they're overrated honestly. Audiobahn subs are also top of the line, but they're more for SPL and expensive too. If you've ever heard of Diamond Audio, their stuff is also good, but expensive -- hence their name. Memphis Audio has good all-around subs, and they're middle-of-the-line prices. Also, if you see "Class D" on amy amplifiers, that also means they're top of the line usually. If means they are powerful but still have under a 0.05% total harmonic distortion (THD) rate. They're what you'd call clean amps. Another thing you have to consider is what kind of music you listen to. If it's more on the rock side, a 10" or two might sound better because they have tighter bass and don't get as low. If it's more hip-hop, 15" might be better -- more low-end beaty bass. The compromise is 12" (well actually 13.5" but JL's the only one I know of that makes that size). Then you have to consider box size. Bigger box means boomier bass because the face of the sub will have more excursion. Also usually two 10's will sound better than 1 12" because the sound waves get more of a chance to interact with each other, and more interaction actually amplifies the sound a little bit more naturally. Well, if you want a technical explanation, that's it.

Zach

Los Gatos?

Sorry White SR5...I have to call B.S. on that one. It is true that 2 10's will be louder than 1 12" at a given wattage, but that is due to more cone area, not 'sound wave interaction,' as far as I know. I also don't believe they will sound better inherently.

Bumpin' Yota

I agree, sorry WhiteSR5, but Los Gatos is correct. The sound of a sub in a given box is VERY subjective to the ear. As to a pair of 10s being louder that is directly due to a larger moving cone area, and a bit more effiecncy in transducing the amplifier power to sound.

It is a general rule of thumb that as you double cone area, you increase the volume by 3db. If you double the power, you also increase by 3db. (This is due to decibel's logarithic scale.)

Now to the 2 10's vs 1 12' example as it's time for some math....

The theoretical cone area of a 12 is 109.9 sq inches
The theoretical cone area of 2 10s is 157.1 sq inches
You therefore have 50% more cone area and the pair of 10s will be 1.5db louder.

btw - a bigger box is "boomier" most of the time not becuase the face of the sub has more excursion, but rather the transfer function of the box has a large peak at the frequency where the "boominess" occurs. If you want more excursion you can just apply more power if that was what you were getting at...

...however then you can run into problems with thermal cooling, over excursion/incursion, back electromotive force (EMF), larger impeadance swings, and the list goes on...
