Feature:
Pretty straight forward, it's a self powered sub. It does allow to input from an amped speaker and have a high pass filter on the XLR outputs, and the JBL logo lights up on the front.

Quality:
This sucker is easily the lightest sub I have ever used (smallest 18 I have ever seen too), and it packs a wallop for how little it is, bass comes clear and precise; I kid you not I used it at a bowling alley, building was made of brick and it made the metal onning outside shake.

Value:
Its a great subwoofer, truly a great addition to any collection that's in need of bass.

Desirability:
Easily the sexist subwoofer I have seen =)~

Sound:
The sucker puts out the deep lows you're looking for in a Sub, and tons of it. Drawback is it could be louder, when I pushed it to around where I wanted it, the red clip light started coming on.

Ease of Use:
You plug it in, it works =)

Support:
Haven't had to use it yet for this product, just got it.

Overall:
This is a great Subwoofer for anyone who is once again looking to add some punch to their sound system. Sound quality, weight, looks, and convenience of the product are amazing: top notch; my only drawback is you could probably find something louder for around the same price, but easily at the expense of the above features. If sheer volume is key, and all else does not matter, this might not be for you, if your looking for an easy to use, deep, clean, sexy, and ultra portable sub, look no farther!

Feature:
ALL THE FEATURES YOU NEED IN A POWERED SUB. PUTS OUT 500 CONTINUOUS, 1,000 PEAK. YOU CAN DAISY-CHAIN IT WITH ADDITIONAL SUBS. HAS A BUILT-IN CROSSOVER WHICH IS GOOD, ALTHOUGH IT IS NOT ADJUSTABLE. IT IS VERY LIGHTWEIGHT, WHICH IS A HUGE PLUS WHEN YOU'RE GIGGING A LOT OR TAKING YOUR GEAR UP AND DOWN STAIRS.

Quality:
JBL BUILD QUALITY. JBL HAS NEVER FAILED ME SO I TRUST THEM.

Value:
FOR YOUR MONEY, THIS REALLY IS PROBABLY THE BEST POWERED SUBWOOFER ON THE MARKET RIGHT NOW. AS YOU CONTINUE TO RESEARCH OTHER SUBS, YOU'LL EVENTUALLY DISCOVER THIS TO BE THE BEST POWERED SUB BANG FOR YOUR BUCK.

Desirability:
IT'S SEXY. YOU'LL LIKE IT.

Sound:
SOUND IS SOLID, IT THUMPS PRETTY NICELY, HITS YOU GOOD. IT DOES NOT PROVIDE A ROOM-FILLING RESONANCE THOUGH. IF THAT'S WHAT YOU ARE LOOKING FOR, YOU WILL NEED TO BUY TWO OR THREE OF THESE AT THE VERY LEAST.

Ease of Use:
PLUG IT IN, TURN IT ON AND BANG AWAY.

Support:
HAVE NOT HAD TO ENLIST JBL'S SUPPORT SO I DON'T KNOW WHAT TO SAY HERE. I IMAGINE IT'S TOP NOTCH...?

Overall:
I WILL LIKELY BUY ONE OR MAYBE TWO MORE OF THESE EVENTUALLY. DON'T GET ME WRONG, ONE SUB HITS FAIRLY HARD BUT FOR REAL ROOM-FILLING, CHEST-MASSAGING RATTLE, I KNOW I WILL NEED TWO OR THREE OF THEM WORKING IN TANDEM. OH, AND I WILL BUY IT FROM ZZOUNDS FOR SURE. THEY DID ME RIGHT ALL THE WAY... FLAWLESS TRANSACTION, LIGHTNING FAST DELIVERY, AND THEY HOOKED ME UP WITH THE INSTALLMENT PLAN. NO HASSEL WHATSOEVER. DEALING WITH THEM WAS SO EASY IT WAS ALMOST FUNNY.
