subs that compete with 05 XXX that cost less than $350 each

and exactly how long did it take for it to give you this "magic smoke"

well i played it for about 15 minutes at close to 1600....and the sub is broken in....when it started giving off the funny smells and bad noises. the noises were what sounded like some non linear excursion. very, very sloppy.

ive played mine way longer than 15 minutes and no funky smells or smoke..... i dont know what is up with ur sub, people say the sub can handle 2300 watts daily off music.

imo 2 12in 06 L7's in like a 6 cube+ ported box tuned to 34-37 hz, with a good 2500 watts pump'in them, will compete with a pair of 05 xxx's

a high tuned fart box with L7's will get abotu as loud as low tuned daily boxes with xxx's in them........differance being the xxx's will sound beautiful while getting loud, and the L7's will sound like hooker being beatin to death......

i disagree. ive heard a few setup with low tuned L7's sound real good for their rep, and get **** loud. off the power it would take to MOVE a XXX.

But when it comes to all out SPL the MT/BTL should easily take it....but with more power.

Daily application type power the XXX walks on alot of things

I would doubt that. I would wager that the MT's and BTL's are watt for watt louder than the XXX. The great advantage they both have is very high efficiency due to low Mms; not as great for low end performance, but a very potent feature in SPL competition when combined with their power handling capabilities.

Alot of talk lately about the L7's wining SQ comps. Don't forget guys, the majority of SQ comps are judged at low volume levels. The problems inherant in the square cone design show up worse and worse with more and more excursion. At the lower volume levels of SQ competition the big linear displacement numbers the 'supersubs' put out dont add up to any real advantage, and subs that may not do well at louder sessions (SQL) may still excel at lower volume levels. Im not saying this is necessarily the case with Kicker's L series subs, but they have some definite design issues other subs do not have, SQ trophies or not. Don't let trophies dictate sound preference.

This is going to sound hypocritical because I was once on the anti-Kicker side, but I would have to disagree with some of this.

Yes, a square driver will not be able to excurt as far while remaining linear. BUT, using a flexible surround can combat a lot of this. In fact, whether it remains linear or not will be totally dependent on the suspension and not inherently the shape of the cone. Having seen Cms curves from an 04 15" L7, I would have to argue that there are no suspension issues within the rated xmax. Granted, the L7's have fairly average xmax, but the cone area and excursion combination allows for linear displacement that is equal to or greater than other drivers in their price range without the inherent inductance issues of your typical high xmax driver. It's just a different side of the same coin.

I would defenitely go with mags.

Cone 'break up' does cause problems with a subwoofer, you aren't suggesting otherwise are you Neil?

Im not even saying the L series drivers do have cone distortion at high xmax, honestly I doubt they do. But look at the cone, stiffening ribs added to keep this from happening. More weight, for what? For more cone area. This definitely hurts its performance, even if/when the cone stays stable. I still say you are better off simply going up one size in a round cone sub to gain cone area than you are by purchasing a square driver.

My comments on not letting SQ comps make your decision were based on the fact that these comps are comparing subs (and more importantly, installs) at lower volume levels. We cannot take that as a direct comparison of each speaker's SQL abilities. People are comparing xxx's with L7's here and basing it on 1) speculation of output based on little or nothing, and 2) speculation of SQ at higher output levels based on comps were professional installs competed at relatively low volume levels.

There is a reason you will never see any true SQ speaker come in square form. Im not saying the L series is a 'bad' driver, but it has its uses and it has its limitations, just like every other speaker.

would anyone consider the 12 MTX 9500 in the neighborhood of the XXX? they fit the price bill as far as i can see

Yes, I would.

hmmm.... i'm leaning towards this sub over the brahma's. altho i could score the brahma's for $620 shipped

9500s over Brahmas? I thought you were looking for a 70/30 SQ:SPL split... The 9500s are more like 40/60 SQ:SPL.

I've heard the 10" 9500 plenty of times and its loud as **** ported but its sound isn't for me. They definately don't sound the worst though...
