5Few if any subs in brick and mortar stores can touch this
By D. McNevin
I've owned a lot of powered subwoofers over the last 15 years.M&K, Polk, Infinity, Cambridge Soundworks, Yamaha, Boston Acoustics, Advent.None of these, with the exception of M&K have a sub on the market that can touch this subwoofer. Deep extension, oodles of power and sweet looking to boot.As another reviewer noted, it probably doesn't weight 75 pounds on its own. In the box, yes, thats the weight. Out of the box it's 63 pounds. Still a very hefty sub especially when you consider its crammed into a 14" squared box. I emailed Definitive Technology to get some clarification on the performance specifications on this sub.Although it's advertised everywhere that it will reach down to 13Hz, the useable frequency response is down to a more reasonable 20Hz -3db anechoic measured. So, in your room you may expect to see this output or even better if your room is on the smaller side (under 1500 cu.ft.)The 10" driver weighs in at over 21 lbs. That's one heavy driver.I'm extremely satisfied with the performance and can recommend it without reservation. However, one thing I do have an issue with is the auto-on feature. I like to listen at low volume now and again. When I do this, I lose the bass response in my system because this sub requires a stronger signal to turn it on. I think Definitive kind of blew it on this one by not offering a bypass feature that allows this sub to be constantly on instead of needing a signal to kick it into gear.Other than that, this thing is truly a stellar performing subwoofer.

5Was that a Jet Airplane or the DVD?.....
By JCP
Compact cabinet for so much sonic energy created. This sub woofer rocks the house. The first time we heard it kick in we thought the sounds were coming from a truck or plane outside the house. Great controls for cross-over, phase, etc. Good selection of connection methods too.

5Good subwoofer
By ThickMec
This was purchased as the sub for a system in which I have 3 Mythos Tens for front left/right/center channels and 2 Mythos Gem XLs for surrounds. I have a longer review of the Mythos Tens for those who are interested.This is a good subwoofer. Relatively compact, powerful, tight bass response. Easily rattles the walls when I wnat it to in our 14'x20' family room that is open to the rest of the house. In my system I crossover at 80 Hz, which seems to be about ideal for the speakers in use.
