More than enough solid bass for any application.

No auto-on. Starts to die below 25Hz.

I bought this sub (PF-1500, not the newer TL), used several years ago. DefTech is notorious for not giving meaningful specs on their products and relying on "awards" in their ads. When I bought it, it was available for $1000, take it or leave it so I figured I made out pretty good as it was only 3 months old.

18 months ago I upgraded my main speakers from PhaseTech 730s to Infinity Overture 3s and also went Dolby Digital (Sony DB930). I used the pre-amp outs to the sub and ran the Infinitys full range. I always had trouble integrating the sub with the mains and thought that the sub was just too "Peaky" between 25Hz and 80Hz. Today I got a sound level meter and discovered that the Infinitys were more full-range than I thought and that the sub didn't need to be run much at all to become overpowering. So I switched the front setting on the receiver to "small". Wow, what a difference. My opinion of this sub has changed almost overnight. I did change the connection from pre-out to subwoofer, so now the receiver's internal crossovers are used. It is located in the right front corner of the room for maximum room loading, and it kicks! It does drop off quite a bit below 25Hz, and I need a notch filter to tame the worst peaks. But overall, I am (and generally have been) very pleased with its performance. The newer version is less expensive (competition is a wonderful thing) and probably better.

It's versitility, The sub delivers deep clean bass that you can feel and hear, and is not boomy

My 1500TL has proven to be a very dependable sub. I too will atest to the wounderful kick, and mellow sound that this sub is capable of producing. I found the sub to be the best in its class. I just completed my basement and also added a second sub for movies. If you want to hear and feel a real life movie theater try two of these babies. One would do the trick, however, if you want to experience a step-up try two. Many of you say: You only need one. How would you know if you never experienced two.

Low Very Powerfull Bass -- Lots of air movement!

Auto on (but who cares, I just leave it on!)

I bought this sub after finding out that the bose acoustimass series has no bass. This definatly adds rumble to our main HT and sound great too. We had to fiddle with position a little because it is a boomy sub. I set it up in a corner firing across the room (parallel to the audience) and things sound very good now. My brother tried the THX Test Laserdisk on it and it performs great. This is a great HT subwoofer, I highly recommend it.
