awesome sub, best sub I have ever heard in my life!!!! not even in money catorgory, this thing pounds and under powered

none soooo far,kinda stuff, but still does great in ported box off just 600 watts. try it ported man if you still have it

Well,i have mine in a ported box running off 600 wattsrms. The box is 5 cubic foot. 70 inches of port and tuned at 36hz, damn!!!! kills the aw1500 audiobahns, no crap, within 24 hours ripped the trunk latch off and was just sitting in the bottom of trunk, wow, now trunk latch welded back with brass, holding so far, the reason why it didn''t seem so well for our first reviewer was cause this sub is really meant to be ported. I had it in a sealed box with a little more power and didn''t do 1/6th of what it is doing now

This sub has come to my every expectation. if givin the correct wattage and box airspace, it can do about everything. It can hit high bass frequencies with ease and grace, and commands the sub-level frequencies with power and authority. in it's box, it's about 60+ lbs, and around 8 hertz at 130+ decibles, the box literally jumps. RAD!!!!!!!!!

you need a lot to power this baby. it can take anything, but to get supreme sound, you need raw power (600+ watts rms at least, and clean). it's expensive, but if you go with this sub, obviously that isn't an issue.

My friend owned this sub before me, and blew both of it's voice coils while experimenting. After hearing, and feeling, what this sub can do, I decided I had to invest in one. I haven't been beaten yet at stop-light compititions. It's great. Getting a hold of it was quite unplesant, going through UPS (my first was broken because of the packaging). so even though expensive, and waiting about 5 months to get it, it was worth it after putting it in. I'm happy, and if I upgrade, it will be to get a second.

Two 12" MTX's in a bandpass box- a disgrace in comapison.
Two 12" PYLE comps. sealed- can't put out like this beast. no low end either.

Looks pretty good, if put in right can hit hard, musical except for the bass 35 hertz and down it doesn`t hit hard.

The main problem is that the spiders are too tight, it might help clarity on midbass, but keeps the lowest bass from hitting.

I installed this in two different sized boxes (2.8, and 2.2 cu. ft.). the larger one could hit deeper, but couldn`t play the lowest notes as good as the smaller one. Unless you put this sub in the recommended box it will push full throw at 500 - 600 watts. By the way the sub acts it would sound more like a good ten, than a fifteen in the small boxes that Audiobahn recommends. It has a lot of trouble with the bass hovering around it`s "fs". It sounds muddy, and loose if you get the volume up above halfway, and above that it distorts, not from the amp because I have used it with many other subs. This fifteen doesn`t sound anything like the 18 version of it, the 18 is a much better deal it hits a lot harder, it is clearer, and twice as deep. Just save a little more money and get it instead.
