I have this sub. I am not very experienced as far as subs go. But, here is my experience. My last sub was an Enerby XL-10. I was running this (the 10) with KEF speakers and it was a "match" for the system although I was disappointed with the lack of throaty lows. If I upped the db on the sub to where I liked the bass, I got this funny deep vibrating sound at times of quiet. When I upgraded my system (pre and amp) along with my speakers, the 10 couldn't keep up with my system.
I reluctantly tried the Microstar. The guy I buy audio stuff from really pushed it saying it was a super sub - better than the energy 18. I didn't want to offend him, so I took it home and figured I'd bring it back. I still have it. After breaking in this speaker has really got it going on. As I mentioned at the top of this message I really don't have a lot to compare it to (I have never heard a Velodyne 18, or a Bag End 15 for example). I can tell you though, it keeps up with the rest of my system and really puts out the bass so much so that I can feel it in my chest and can feel the floor and furnature vibrate. With some movies, like Saving Private Ryan, I cranked up the battle scenes and I couldn't detect any distortion (but then with all them bullets flying around it's hard to think stright!) The only distortion I have ever heard was in the DTS version of Dances With Wolves where Kevin discovers the buffalo at night. I think that, the only image I have to describe this, is a heart fibrillating. It is almost as if the sound is so loud and deep and needs to end quicker than the speaker can end it, and then then the next sound comes along, and while it is ending one sound, it is starting another.
Other than that one place, my whole experience with the Microstar is that it keeps up with anything else I throw at it. To give you a point of reference, my speakers are Energy Velodyne V2.3 mains, Energy Velodyne V2.0C center and (what else?) Energy Velodyne V2.0R rears. I am running this against a Parasound AVC-2500u preamp with a Parasound HCA-2205 amp. I am sitting 9.5 feet from the mains and 8.0 feet from the rears.
I have also seen some reviews of the Microstar at http://www.audioreview.com/reviews/s.../index_E.shtml
which gives you more input.
Have you bought or thinking?
