I have spent a fair amount of time with this subwoofer. Here is my review so far.
Music: I listen to mostly rap/alternative and some country. So, take my obseravations with a grain of salt. I really enjoy how this subwoofer plays the lows in all the music I put through it. Beefy is how I describe it. Is it accurate? Probably not, but the music I listen to mostly, accuracy isn't formost in the producers mind. Other than some DJ Magic Mike, no frequencies were missed in any songs I played. I was also pleasantly surprised how well the sub blends with my Mirage speakers. I wasn't expecting the 12" sub to play as well as it does up to 100hz. Granted, my old Polk 8" subwoofer blended better with like sized speakers. But I will take the trade-off of deeper, more impactful bass over a perfect blend. Just my preference.
Movies: Couldn't be happier. I don't own copies of the movies most people refer to when reviewing thier subwoofer (U-571, Lord of the Rings, etc). I ran the sub through its paces with "Quantam Solice" on the action side, and "Dazed and Confused" on the light hearted side. Q.S. sounded fantastic. Explosions, gun shots, crashing planes and cars. All had the impact that makes a staying home to watch a movie an absolute joy. The impact of a 12" subwoofer just can't be beat. Couch vibrates, chest tingles. Why "Dazed and Confused"? For the sound track, of course! The music just can't be beat. Just like with regular music, kick drums and bass guitars came out clear and forceful. Definitely heightened my joy when watching this gem.
Faults: I find the auto-on not sensative enough. I found a couple times I had to turn up the volume on my reciever to get the sub to turn on. Marginally annoying. If you have a significant other that hates big black boxes? Look else where. Though, not as big as some subs, it really is a big black box.
All in all, I think this sub is a great deal at $150 shipped or so. I couldn't be happier with its sound and overall performance.
Feel free to ask me any quesitons.
