I took our separate dining room, closed it off, and built a custom dedicated listening room. I custom hand built all room treatment. I built diaphragmatic bass absorption into the front and rear wall. The room is small, but allows a full range speaker to deliver a spectacular full range musical experience. Fairly even frequency response down to 30hz. It's taken a lot of work, but well worth it.
Morgan - way to go! Your room looks amazing and the attention to detail and effort is second to none. Kudos. Like you, I've treated my room and firmly believe that acoustical treatment makes a huge (50%?) difference in sound quality. Mind if I ask some questions about the treatments?
* what kind of treatment is directly behind the listening chair on the back wall?
* what's the max length of the Skyline diffusor blocks?
* do you find having so much wood in the room sounds different and better than normal drywall or plaster?
