 So, this is much better overall. It shifted the dip to 72Hz, and softened it some--looks like some of the other FQ were also positively affected!!!  |
Yeah, looks much better!

Does it have a time delay setting for the mains and/or the sub? That would work equivalently, where 1 foot ~1 mS. The shorter the time, the "closer" the speaker.

Question: Just for complete clarity, I don't have to do anything other than plugging in the L channel and turning on my mains to test this, right?
|
That sounds correct. Additionally, I'd just leave L and R connected from the PC to the AVR all the time. Then, mains on, re-run the sweeps.

BTW, Ken (I'm sorry I've been calling your Bruce  ) would you advise a small boost of that 72Hz? If so, how much would you guess at what bandwidth, etc.?

I would try it if I were you (or Ken, but I know brucek won't recommend it
). Looks like it's almost 10 dB down from where you are at 60 Hz. Just watch your levels. Does it sound better? Another alternative is to turn up everything and continue to quash peaks. Also, are there any filters already nearby that you can tweak with?
