Room treatment...what is the goal?

Is the goal to get rid of all echo in the room, or do you actually want to have some room echo. Are you aiming for a flat response? What if your speakers aren't perfectly flat, and have sloped up highs? (which I believe is the case with my B&W 805S speakers) Are you trying to match the anechoic response or at least be somewhat close to it? Also does anyone have the response measurements for the 805S? I can't seem to find them anywhere.

I just treated my room with the help of an acoustical engineer, and while everything sounds great, the highs almost seem too dull now on my 805S. They used to be too bright before treatment, but now they seem like they have lost a little of their sparkle and presence. Everything else sounds 10x better though

Depends on the room size but an RT60 of around 0.4 to 0.8 is desirable. You can allow RT60 to get over up to 1.2 or 1.4 at 20 Hz.

0.4 is closer to dead studio sound and 0.8 is closer to what may sound best in classical. The smaller the room the more important it is to lower the RT60 value.

The worst thing is to have an RT60 that varies all over the place (drastically different at different frequencies)- this will sound terrible.

Look at my virtual system for some measurement examples.
