In-Room Frequency Response

High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

Hey folks,
Despite the infinite number of placement/treatment options, I currently have -/+ 5dB across the board from 40Hz to 12.5KHz for my BLHs. Actually, I've got a -5dB dip at 80Hz, a +4dB peak at 160Hz, a -5dB dip at 315Hz, pretty smooth out to 3150 Hz, and then a +5dB rise (going back to 0dB) between 3150Hz and 7000Hz. I can listen more on axis to bring the highs back in without too much fuss but my ears start to roll off after 10K to 12K Hz anyway so I'm not too worried about it - I prefer the smoother midrange response. The bass is as good as it's going to get unless I push the speakers back against the wall, which I really don't want to do.
I'd like to get rid of that hump between 3150Hz and 7000Hz. The only room treatment I have in right now is on the front wall between the speakers. Speakers are approximately 4' from the sidewalls and 3' from the front wall.
So, if I can establish -/+ 5dB on average between 40Hz and say 15K Hz (by turning in on axis a bit), is that good enough for little Fostex FE166ES-R drivers? I know there's no perfection but I think I'm close to as good as it's going to get. It's sounding really good (to me) right now.
Any thoughts on how to get rid of that 3150 Hz to 7000 Hz hump without really messing with things? I'm thinking treating the first reflection points should do it. What affect would phase plugs have? Or, a bit more wool in the compression chamber?
Thanks,
Jim
