Thanks jond. I checked out your system page. I'm a big fan of Audio Note speakers and the tube gear looks awesome with some nice upgrades! Congratulations on a great looking system!
Hi, highend 64. Thanks for the comment. I had GIK do the entire room design and I followed their recommendations. Because of windows, CD shelves and a front door on the rear wall, it was not feasible to properly treat the rear wall behind the listening position. I think the rear wall treatment is preferable, but as long as one wall, front or back, is properly treated, you get the same acoustic benefit by killing and diffusing reflections. GIK recommended the front wall treatments and the results have been excellent! What is not shown in the pictures are celing absorption panels and a diffuser/absorber on the opposite side wall, which are also beneficial. In this room size, bass absorption is critical as you likely have found out. I was amazed at how the bass improved with the traps recommended by GIK. GIK does a free consultation and room design. Of course, they hope you will buy their stuff but it was a major improvement to what I had in place before. Hope that is helpful.
