Feature:
everything you might need to adjust it properly, and everything you might need to hook it up any way you might want. Accept there is no adjustment to the xover. This means nothing to me since I use an external anyway.

Quality:
built like a tank. I like that the speaker cones are completely inside and you can't see them. This thing just looks like a big black box.

Value:
I have rated this thing with 9s and 10s. If I were factoring in price and ignoring that this thing is huge, I would give it solid 10s. It makes my Polk 200 watt unit I have upstairs sound pretty boomy and primative. I have heard people say this thing sound muddy. I believe that is because they are used to something much more like the Boomers the kids have where one not goes Boom. This isn't like that.

Desirability:
you betya, It took me a while to realize just how good this unit is because I had expectations of a thump thump boom boom. Which just isn't there. This actually turns out to be what makes it so great. It is invisible (not visually, did I mention this thing is huge?) accept you suddenly have amazing bass in your system.

Sound:
As sub woofers go this is a pretty amazing product. What you don't hear is the most important part. This thing doesn't hit you in the chest with bass. What it does do is make you system sound amazing. Properly set up this thing just disappears and becomes just part of your existing speakers. There is no bang or thud, just lots of awesome clear sounding bass. Although it doesn't go thump, don't let that fool you. There is lots of bass coming out. At one time I had the vents within 4" of my wall, cranked up the volume, and all of a sudden out of the corner of my eye, I noticed this thing suddenly move away from the wall. It pushed itself away, no small task considering it weighs in at nearly 80 pounds, and was sitting on its rubber legs.

Ease of Use:
really big and heavy. But it does make a pretty good end table if you use rubber coasters so things won't vibrate off

Support:
haven't had to use, but the manual was actually pretty great at explaining how to place and adjust this unit.

Overall:
I expect to have this in my studio till I blow it up. I hope that means decades. Probably not the way I go about things.

Feature:
the built in active crossover makes connection easy; 360 watts is an overstatement - I pulled the amp off the back, it's got a 240 watt transformer in it - it is hard to provide any more than 240 watts of electrical power to the amp with this transformer - half of that is lost in heat - maybe you can get higher peaks, but the actual power the amp can supply to the speakers is much less than 360 watts....

Quality:
I don't suggest for anybody to use this product on the road... It is designed for a studio or a larger living room... Again, for this price, you get what you pay for; the whole box is made of particle board - cheap, cheap, cheap... As per the electronics, so far so good, but the unit runs very hot. I am considering removing the amp unit and McGyver it with some pc fans; connecting with heavy cables to what will remain as a speaker unit...

Value:
you can't beat the price

Desirability:
oh there are much more sexy subwoofers on the market, but not at this price

Sound:
quite musical, was able to eliminate my eq which I used at the insert points of my mix's main outs

Ease of Use:
plug and play - you will need to buy your own xlr cables though.... but at this price, it can be expected

Support:
have not needed it so far

Overall:
inexpensive addition of immense bass to your soundscape, easy to integrate with existing monitor system but if you have the money, aim for something (not sure what) better... like a Bryston amp with Electro Voice 18" subs built into a folded horn... Size of 3 dishwashers and 20 times the price :-)
