I have been reading all of the posts about sub eq'ing, and I think I need it in my room. I have the Velodyne SPL 1200, and I am pretty sure I have some peaks down in the 30 to 40 Hz region. My deep bass is just overpowering compared to the mid bass. If I turn down the sub, then the rest of the bass is non existant. I have my sub at like 2 out of 12, and the deep bass is still really loud! My receiver's trim control is set to 0. So, which CD is it that everyone uses for the test tones? I have seen the Stryke Test CD mentioned. Is everyone using the Volume 1 CD? They have it on sale for like $10.95 plus a $1 for shipping. That is cheap, but I am not sure if this is the same one everyone is talking about. What do I use to measure it? Do I just use my Radio Shack SPL Meter? Do I basically just play the test tones at 1/6 octave starting at 20 Hz, and record the SPL for each one? I have seen mention of the Spectra software. Do you just basically use this with the RS SPL Meter plugged into your sound card mic input (using a 1/8" jack converter)? Do I use the analog output on the DVD player or is Digital mode ok? Which EQ is the best? I have seen mention of the Behringer Feedback Destroyer (DSP1124P), but what about the PEQ 2200 5 Band Parametric EQ? Is that just not enough bands to tame a sub? Is that why people like the BFD - 12 bands should be enough I would think. But would 5? How big are these - would it be too big to put on top of the sub? Would the vibration from the sub effect it? I have my sub in a custom built media niche, so putting this on top of the sub would be easier - I can hide it behind the grill cloth covering the niche. I can put it in the rack if I need to, but it is also a custom niche, and I don't have unlimited room in it. How hard is it to hook up the BFD - you just have to get the RCA to 1/4" converters. Does this degrade sound quality at all? Pick up any hum? People spend $200 on a sub cable, and then put a Radio Shack 1/4" converter on it - seems kind of pointless. What about ground hum? Do I HAVE to get a cheater plug? Has anyone had ground hum without it? I will have everything plugged into a Monster Power Conditioner (HTS 1000) if that helps. Once I have the measurements, how hard is it to adjust the BFD? Would the software download help with this? Thanks for all the help in advance. Bryan P.S. The receiver is a Denon 3802, and the other speakers are all Klipsch Reference series, crossed over at 80 Hz.
