left-right corner absorbers with different volume?

Hello, in our studio (see my first post at http://www.johnlsayers.com/phpBB2/viewt ... 610d854e31 ) - currently under construction - we want to place two splayed walls at the front of our control room (see picture below). In the corners we want to put corner absorbers. On the right side we have an entrance door made of glass that we want to keep there to let some daylight in. So we are thinking about a removable solution for the splayed wall in front of the door (thin black lines) that can be put in place in critical situations (e.g. mixing). Our plan is to build a wall element that can be shifted into the cavity of the right corner absorber. Without treating the left corner accordingly this would result in two cavities with different volumes. Now my question is: Does this have any negative effect, especially on the acoustical symmetry of the room? For example, could there be a bass frequency shift between the two corners? Or would this effect be not worth mentioning it? If this problem is already discussed in another thread, please forgive me for double-posting ... in this case I'd be glad if you could post me the link. Thanks a lot Ben

Can you describe the type of panel you would use for the temporary splay, and the distance from it to your glass door? Steve

Hi Steve, we thought about using some kind of plywood for the temporary splay, but we're not yet really sure about that. For the other splay (where - oops - I forgot to mention we'll put our 2nd pair of monitors into) we're thinking about either a panel absorber or a Helmholtz resonator solution. The distance from the back of the panel to the glass door would be about 10 centimeters. I've added a rough top view of my idea and the SketchUp file from my earlier post so maybe it's easier to comprehend. :) Greets Ben
