Diffusion Or Absorption At The First Reflection Point?

2-Channel Audio Systems - DTV Forum Australia - The leading audio visual and home theatre forum - www.dtvforum.info
I've been experimenting with room treatment configuration of late to try and reduce the amount of mids hitting my ears at the listening position.

I'm using a test tone CD and find the most offending frequencies are between 2.5 - 4 kHz.

I built my own diffusers, and although these aren't proper quadratic diffusers, I think they do enough to scatter the sound somewhat.

I've found that when the diffusers are positioned at the first reflection point, the soundstage opens up and more detail in the music is heard. However, with a lot of rock stuff, the guitars take my head off and the sound becomes quite fatiguing. When absorption is used at the primary reflection point, the soundstage closes, there's less 'excitement' in the music, but I can tolerate the rock stuff more.

I've found also moving the speakers away from the walls has reduced the intensity of the above offending frequencies, but also at the expense of soundstage.

I guess I'm struggling to find a happy medium and would like some advice on other things to try.

Cheers,

Linc.
