Thank you for your comments. The monitors are not actually mounted on the wall, they are on stands - a bit hard to tell from the pics. The monitors I use are Yamaha HS50's.There is a compensation switch on the rear of the monitors - they say that, thats what it is for in the brochure, I hope this is true. Do you think this sounds feesable?
Anythings feesable, is it probable that it works? I dont know how they could
"compensate" by one switch for "all" walls. Could be concrete, drywall, plaster, carpet,..etc.
Im sure its just a low mid freq roll off but personally i wouldnt want to
have an EQ switched "in" if i didnt have too.
Put some CD's in of music you know well, try it both ways.
But the most important thing to try is REALLY listen hard to the freqs.
Ignore the music..listen to unpleasant lows (figure out where they are)..
move your ears around, see if the reflections are different sounding
in different spots.
I still say move um away from the wall but if you cant, really learn
the weaknesses of your setup and always keep those freq's in your mind
when you're mixing.
