This is where I arrived after trying different gear over the years. I just move a chair into the sweet spot when I want to listen. The room is live, but the beaming speaker design, high ceilings, and being open to the main level allows it to sound great without room treatment.

While my system did sound good, the South wall setup did have bass loading and cancellation problems. With the gear between the speakers, I would get awful feedback from the TT at around 80dB. That put me back to the West wall setup as I only had one corner to worry about. Moving the left speaker further into the room helped solve that, but it did put me close to a back wall. The South wall setup is ideal as it is open to the main level keeping me far away from a back wall.

To solve the South wall problem, I added four GIK Tri Traps, stacking two in each corner. I also added a small area carpet between the sweet spot and the speakers. The bass is much improved and well defined now. Imaging and separation were also improved. While not pictured, I do have four GIK 244 bass panel traps. Adding one 244 on the wall behind each speaker moves the sound stage out. Placing a 244 on the wall next to each speaker narrows the sounstage, so I have removed them.
