Here's where a cheap electronic room correction device like a Behringer, etc... can work wonders. You can either install it into the system permanently and let it do its' thing OR use it to take readings and then adjust the speakers to minimize the amount of correction needed. If you don't notice the sonic effects of having the Behringer hooked up in the system, there's no sense in removing it and having to perform more manual labor. In a case like this i.e. where both the ceiling and side walls are quite different, you might find that the sonic intrusion of leaving the Behringer operating all the time outweighs the drawbacks. That's because you may never be able to correct for the room's odd acoustics even with fully optimized speaker placement and / or changes in your seated listening position. The fact that you can take the Behringer ( or similar device ) with you wherever you move to and that they can be found at quite reasonable prices is far more advantageous than trying to treat a room / listening area that is far less than a permanent residence. Hope this helps... Sean
