Well I watched the movie "Wanted" today, while I would not recommend it from an aesthetic, or artistic point of it does have lots of "boom factor." I had the TH-SPUD upfiring with the BFD in place.
I used the Pioneer MCACC to calibrate the room, and it set the sub at -8db. I boosted the signal to -2db, because I wanted to feel the movie, and I was testing the sub after all.
Let me digress, I did a bit of research on my NAD 2200PE and I found this quote;
"The NAD 2200 is so powerful in the normal stereo mode that few listeners will ever need more. For special situations the two channels of the 2200 can be bridged to form a mono amp of truly immense power. Its rated continuous sine-wave output is 400 watts, while its dynamic power output exceeds 1200 watts into 8 ohms and 1600 watts into 4 ohms"
So I guess for the moment I do not need to look for another amp.
Meanwhile back to my impressions, with the system thus configured and the sub about 8' behind the listening position, I watched to the movie. The bass seemed as good as the DS15-combo, I could feel the things I believe I should feel. Everything felt tight and fast. At the end of the movie there is a "theme song" with fairly heavy bass, so I cranked the volume up from -15 DB to -7 DB before I heard distortion, remembering I had the bass over by about 6 DB according to the way MCACC wanted it setup, I think it did really well.
This is rather subjective, and I will get back to the objective soon.
