Query: great sub for a small home theater

I got this sub-woofer for my home theater which is also in my bedroom. It took me a while to find just the right place in the room where the sound blended well and I could no longer localize the sub. compared to my older much smaller sub, this thing is a vast improvement. I can see how it might not fill a really large room, but my room is about 16x9, and it does a fine job. In combination with the small JVC satellite speakers I have around the room (6.1 setup), I've really gotten that 'movie theater' sound. My only complaint, (and it's a small one) is that the sub's auto on/off feature will occasionally turn the sub off during long segments of time with no bass, such as a part of a movie or video game that's just dialogue with no music or SFX. If you find this to be a problem, just set the sub to ON rather than auto. over all, I'm very pleased. it's helped make Monday night our family movie night without having to leave the house.
