I posted this over in the DIY forum and did not get the answers I need. If I do need a BFD, where should I start with setting up the filters on it? I don't have a clue as what to do! I know it can hit harder than it does now from what I have read.
I just got my Tempest AA up and running Saturday 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 Sunday and here is what I got. 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 I think it should 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????
