Feature:
everythings is vesatile about this sub, you can lay it down for even more heart renching bass!

Quality:
you could drop this thing from the top of my house and it would probably survive with no rattleing in the box!!

Value:
no better sub for six hundred!

Desirability:
VERY PROFESSIONAL LOOK!

Sound:
well i can't say enough about this sub, driven by the qsc rmx 2450 i'm puttin 750 in at 4 ohms and it sounds suprisingly strong even at the highest of spl....(sound pressure level). yes of course when you push these bad boys to the limit you may feel a little light headed because these things have broken 2 of my windows already. best bang for the buck.....anywhere!!!!!

Support:
in the middle of a dilema that i caused!

Overall:
I WILL NEVER LONG FOR A BETTER SOUNDING CAB. YOU JUST CAN'T GET BETTER THAN THIS, I'VE HERD ALL DIFFERENT SUBS....CERWIN VEGA,MACKIE,COMMUNITY,YAMAHA,OR WHATEVER THEY HAVE IN THE SHOW ROOM AT THE TIME, BUT THESE JEWELS WILL ALWAYS BE NUMBA ONE!

Feature:
I haven't had to transport it yet, but its wheels are helpful.

Quality:
Very solid structure. Has a great look. Easy to hook up and use.

Value:
Worth every SINGLE PENNNY. Again, when used with one channel on the CE2000, its a perfect match.

Desirability:
has a good BOOM

Sound:
Has a nice deep sound. It can also get pretty loud. Worth every dollar. Sounds awesome when paired with the Crown CE2000 amp... they have similiar clipping points.

Support:
I haven't had to use support yet

Overall:
I think this product outdoes the Mackie 18" Powered Sub anyday....this sub has very powerful 15" subs in it that hit very hard. Despite the heavy weight, its still one of the best subs i have ever heard. I would recommend it to anybody that wants a very powerful addition to their setup.

Sound:
This is a fairly decent sub. Ive found it to perform better at 100hz or below at high SPL I typically cross these over at 80hz so I can drive them harder I would not recomend using these without an active xover. The series inductor on this cab xovers at 300hz with a 6db per octave slope (first order passive) This allows way to much mid range through the sub and you can smokem alot easier with this high xover point Obviously they are not EAW but they do a fairly decent job for the cost.

JBL is one of the premier "American" speaker manufacturers. They offer a wide range of excellant sounding, superior quality speakers in a variety of price ranges. JBL basically has something for everyone that demands top-notch performance without spending a fortune. But, JBL's will sound like you did!

Feature:
Built in casters and nice steel handles.

Quality:
Great quality made from ply wood with tongue and grove construction.

Value:
One of the best subs for $600.00.

Desirability:
This sub is mean looking and sounds mean.

Sound:
This thing booms like you would not believe when driven ba a peavey 2600 in bridge mono.

Support:
Have not had to use them once yet.

Overall:
This is a great product from jbl that has great value and sound. I highly recommend it to anyone.

Prone to doubling with high input...tends to overdrive early... It doesnt have the deep deep bottom I thought it would have. Needed a sub that was easily transportable, so got these...have heard better.
