Here are the ugly corrected numbers. 10Hz - 75dB 12.5 - 77.5 15 - 88.5 17.5 - 87.5 20 - 84.5 22 - 87 25 - 85.5 28 - 83 32 - 83.5 (yeah, so far so good, but watch this) 36 - 92.5 40 - 99.5 45 - 97 50 - 95.5 56 - 90.5 63 - 91.5 (95.5) 71 - 85.5 (85.5) 80 - 87 (86) 89 - 85.5 (81.5) 100 - 78 (69) 112 - 78 (75.5) 126 - 73 (73) The parenthetical numbers are the readings I got when turning the front speakers on. Notice at 100Hz that with just the sub, I'm getting 78dB and with the sub and speakers I'm getting 69dB . Whatup with that? The speakers shouldn't even be getting a signal until 80Hz, I thought, as I have my Technics SH-AC300 set to sub - yes and speakers - small. Obviously either the Technics decoder or the Technics receiver is not doing its job (correct?). Anyway, those are my numbers. My brother-in-law has a Behringer DSP 8000 (looks old) that he's not using. It says it's a 31-band stereo graphic EQ/realtime analyzer/auto room EQ/parametric EQ/feedback destroyer/delay/gate/limiter/level meter (whew). Is anyone familiar with this unit, and could I use it to help tame my nasty peaks at 40,45,50,56, and 63? It has mic inputs on the back and what appear to be 1/4 inch analog inputs and outputs (?). So, if I can use it, how do you do it? I used Stryke's test CD with the 1KHz test tone registering 77dB at my seat (was going to go up to 80, but it was rather loud). All readings are at my primary listening position about six feet from the sub. Any opinions would be appreciated. Thanks. Steve P.S. I'm starting to think I was better off not knowing, as I was already very impressed with the sub . Oh, well, nothing I can do about it now. I was just hoping to have one of those magical rooms that was relatively kind to the FR. Doh!
