OK here's the basics:

I'm a composer, so the computer and monitors are surrounded by controller keyboards and synthesizers, long hard surfaces on all sides except the back. the room has a notably short ceiling, 6' 7" tall 13' wide and 23' long. Carpet, and 2" rock wool traps on the ceiling above the listening area. 4" rockwool bass traps in the corners, (covering PA speakers there). Foam wedges randomly on the walls, not ideal, but they at least get rid of high end echo... So this reading is with this already in place... Decent monitors, Focal CMS 65's, a mediocre KRK sub, and and EMM 6 for taking readings... I'm not expecting miracles, there are obvious issues with the room, but it's fairly dead, with some noticeable dips. There is a lot of phasing on the high end, but it seems pretty tame in the waterfall to my untrained eye?
Suggestions?? I'm wondering if dips at roughly 300 and 2.5k are issues?
1/3 smoothing applied to full SPL reading only.

Just to add.. I don't really know how to read theses results, are they decent? Is the room too dry? I'm still really new to reading these types of graphs and have no real clue, just information on what I've done so far..

Best to upload the .mdat file to help answer those questions.

Many thanks, here it is.

Room is on the dry side, with decay times at or below 200 ms from 150 Hz up, but very uniform, looks good I'd say. Low frequencies well controlled as well. Did you measure with one speaker+sub playing or both?

Lots of 2nd harmonic distortion in the measurement though, especially below 100 Hz. Presumably from the sub.

The measurement was made with both right and left speakers playing.
2nd order harmonic distortion in the low end is probably due to the KRK having a 50hz low end crossover, and the Focals switching between 45, 60 etc. so setting it for 45 my guess is it's bleeding through around there?
