I just got my Tempest AA up and running last night. I watched Matrix Revolutions as the first movie, (I've been saving it just for this). I can say it kills my 2 Sony SA-WM40's down low! I set it up 5 dB hot and my room is 2900 cubic feet. Volume was set to -10dB and I sit 13 feet away from the Sub and speakers. The Tempest spit out a little bit of Polyfil from the ports sometime during the movie.
I ran some test tones today and here is what I got. I started at 75 dB @ 16 Hz but found out the center was also on so I unhooked it and got 73.25dB and just left the volume set where it was for the rest of the test. The SPL's are with just the Sub running. Receiver @ -11 dB.
Hz------SPL------corrected (is this right??)
16------73.25------84.75
18------79.5-------87.5
20------82---------89.5
22------86---------92.5
25------88.5-------93.5
28------92.5-------96.5
31.5----93---------96
36------95.5-------98
40------94.3-------97
45------95---------97
50------99.5-------101
56------95.5-------97
63------90.5-------92
71------95.5-------97
80------88---------89.5
89------84.5-------86
100-----82---------84
111-----83.75------84.75
125-----65---------65.5
142.5---64---------64.5
I had my crossover set to 80 and only the Sub running. The room has some vibrations, I don't know how that plays with the meter readings I got. I did fix 2 of them but, didn't take time to find the others. I was afraid I would burn the voice coil up???
The Tempest doesn't seem to have the impact in the mid freq. that the Sony's had, but it shakes the floor and rattles the marble in the coffee table like the Sony's never did!
So, Do I need a BFD????
