Jaycee, thanks for the response.
I ended up buying a different instrument to test with, after some people had pointed out the flaws in the methodology I was using here, and using different test methods. Some of the things seen in the graphs above were artifacts from the RS meter used, but not all.
Using my Terrasonde The Audio Toolbox 2, a handheld, calibrated SPL meter, tone generater, and real time spectrum analyser, I did the tests again with pink noise and slow C weighting. I found that I had a high-frequency and a bass problem. The high frequency problem was mainly caused by reflections from the walls it seems; hanging a rug about 2.5" from my back wall solved most of that. Right now, my in-room response abve about 400Hz is within +/- .5dB! The difference is amazing... Imaging improved incredibly, and the system sounds 'calm' now.
As for the bass problems, I tried building some traps using the mthods found in an article on headphone.com, but I made some calculation mistakes, so they did more harm than good. Then I found the ASC website, they sell accoustical products to deal with room acoustics, and offer a free consulting service. I have provided them with room and frequency response information, and they are working up a solution for the bass problem. We shall see what comes out of it...
Niels.
