The living room is 19 1/2' x 28'. The system is set up on the short side of the room. The house is constructed with plaster walls with the equipment wall sound treated with painted cork and a quilt. The speakers are set up 38 inches from the rear walls and the sidewalls are within 40 and 55 inches from the sides of the speakers. The Vandersteen 2Wq sub are set behind and to the right of the right speaker, a little cramped but I ran out of room. The speakers are rear tilted 1 in as suggested by Vandersteen. The living room floor is wood on slab with a large 9' x 16' Durrie carpet. There is 15' of floor to ceiling glass windows that probably add a little glare but not sure what to do about it. Eames Chair is located 13 feet away from the center point of the speakers. The room opens up to the dining room and the kitchen, which adds another 29' more feet behind the listening position, so the sound does not bounce back to me. My wife is a Master Quilter so her art is hanging up which helps with reflections. It also helps with the WAF big-time!
The current distillation of equipment has come to me over years as my hearing, taste or interest ebbs and flows.
