Thanks Glen. Yes it's "A" grade plywood. Nice and light but really strong. The insulation is supposed to arrive today!
I've finished the new treatment and got my new monitors (will post pics shortly). It sounds about a million times better. One issue though, it's still louder on the right hand side by a few db. Some times I can really notice it and other times I can't. Playing a track and some test tones in mono I can here a few things like snare drums sounding slightly panned to the right. There doesn't seem to by any difference in frequency response, the right does sound a little bit brighter but I think that's just because it's louder. If I pan left to centre the mix it the response sounds fine. I've moved the right monitor away from the desk and in towards the middle of the bass trap which seem to help suggesting I'm getting a build up there. Any ideas? Any tricks on how I can test this better? I don't have stereo pair of mics so I'm not sure how to test it.
best bet - Room EQ Wizard (REW) and test each speaker independently. if could be your ears also so even if you find only minor differences (hopefully) via REW, you might still need to adjust levels to accommodate your hearing.

I am a little right ear dominate, I'm trying to be aware of it. I've been checking against headphones. a I've got a friend coming over tomorrow for a second opinion. I'm going to give REW a go. I tried it a once before in the old room. Although I understand what the program does I hate that program, to confusing for me. They may have updated it. A question for you, I can cope with general listening, iTunes etc being a little out of balance. My main concern is recording and making sure I don't end up with a lopsided mix. Anyway, back to the question, if I'm using Pro Tools is there any consequence in just simply putting a trimmer plugin on the master fader and bringing the right hand side down 2 or 3dB? I like this approach because, apart from the fact my new monitors don't have any level trim on them, I can easily bi-pass the plugin to cross check. EDIT: I forgot to mention that I've been experimenting moving the right hand monitor around. Pushed it into the corner, moved it out of the corner, added more bass trapping, less bass trapping. It didn't make much difference, in fact the original position seems to be the best.
it's always a struggle to find the right spot - shoot for best LF response and imaging. when in doubt imaging is likely to matter more for most people. you could trim the channel to compensate - the key is that your mixes translate so you might set up a process where you can have some friends check them periodically - plus use some tools (SPAN or equiv is good) to look at the overall levels across your final mix and consider making a "mix" of noise where you compensate on the monitors and then adjust the l-r levels in various steps and see (using the tools) to see if you are balanced in the mix even though the monitoring is skewed...

Does the new treatment include the broadband corner absorption...'cause all I see are empty corners and speakers reflecting off the desk.:)
