I would agree this looks way better.. What did you change? Speaker positioning? Listening position?? The peak just below 1K is almost certainly a reflection caused comb filter as Ethan pointed out..

Hi Francis,

Thanks for peeking in. I moved both the speaker and listening positions into the room further, and the listening position is closer to that 38% area. That brought up some low end, ( plus the addition of a few 6" traps). What made a big difference was putting my sofa in front of the console. That big null and peak between 90 and 200Hz flattened out nicely after that!

Almost there I think... Having the speakers on stands has introduced some new anomalies for me, as I'm used to how they sound on the meter bridge. I'm thinking of some sort of diffusion above my head...I have a 703 panel there now. The sweet spot is real narrow, and moving my head just a few inches changes thing quite a bit( hi freq phasey stuff). Would that help scatter things a bit?

Thanks again to Ethan,too!. This has been challenging, but quite the learning experience as well.

Regards,

Gio.. (delayed response here)..

I don't suggest diffusion over the listening position in a production environment.. only (possibly) in home theaters or other environments that need spatial enhancement, where you won't be changing the way productions sound!!

Small phasey problems in the top end can sometimes we corrected with very minor adjustments of the final speaker position... balancing out the toe-in, exact distance symetry, etc..

otherwise, you've go an early reflection/comb filtering issue and it needs to be treated with absorption...
