Hi guys, i`m from Israel, producing electronic and "post-rock" music. I just moved to a new apartment with my girlfriend and am forced to work in the livingroom as the bedroom is to full of stuff. the livingroom needs treating as it reverberates heavily, and i`m thinking about constructing DIY panels and basstraps, but I can`t think of a single good place to place my listening position and nearfields. I understand that the best thing in this room size is to work next to the shorter walls, but as u can see, the windows and moveable door/window will interfeer with any tretment, and i really don`t want to put anything on them.
can i work in a corner like the top left corner? it`s the only solution i can think about. what do u guys think? please give me your opinion on the ideal listening position under the circumstances and what kind of tretment would do the trick, thanks for any help.

P.S
this is not a recording room, just for mixing and doesn`t need to be top quality listening enviorment, just ok quality,it also doubles as a livingroom u dig? thanx for any help guys!!

That corner could work, but you'll need a LOT of absorption; the corner behind the mixer should be completely absorbed, also at least half of all four walls and about half the ceiling. mid-high frequency sounds fired into a square corner will reflect back parallel to the source, so early reflections are the main problem...

OK thanks, any other suggestions? what about working in a different spot?
no chance?

You could work at the top center of your drawing, if you can build a portable absorber to slide behind the speakers (and one for each side wall) - these could be stashed out of the way when not in use. 50mm rockwool batts in light wooden frames (no back, just corner reinforcement - otherwise, absorption is limited to depth of the material instead of total depth to the wall) - something like this

That's about all I can think of... Steve

How about putting panels on the walls in the the top left corner and building a big gobo to put next to the left monitor?

Close; you need both sides of the mix position to be equidistant if possible, otherwise the least would be heavy absorption both sides. Symmetry is the key thing here... Steve

sorry, i meant putting panels on the top left corner and a gobo next to the right speaker symmetriclly. in the picture the red line is an absorber panel, the green line is acoustic foam and the blue line is the gobo. will this work?

Somewhat - to work WELL, you'd need REALLY thick foam or at least 75mm rockwool on all three sides, preferably spaced a few inches from the walls; you'd also need both sides to extend far enough so side reflections are absorbed; and you'd need a ceiling "cloud" of the same stuff. But the basic concept is good... Steve
