These are measurements about 18" from the bow tie, between the P-Audio driver and the sub array. Mainly for doing level matching between channels, since I seem to notice on some tracks the center image being pulled towards the right speaker (could be my room). They match well. A couple of learnings.
1) I must really like bass. I love that the Super Vs accommodate what sounds good to me. I don't think I could ever go back to a speaker that doesn't let me adjust the level of frequencies < 100 Hz independently again.
2) I have no idea what the 10 dB dip at 1.8 kHz is. Could it be a reflection from my desk on the right, or some sort of cancellation from the front wall?
3) These are really the first speakers that have sounded excellent in my room -- I know that I have added the bass traps, which also help, but I think something has to do with the extra LF energy, the slight depression between 1-3 kHz and the extension down into the 20s.
4) Maybe my subs a bit too loud right now
