Warnerwh,we must have the same room.Live end ,dead end.Jon Risches tube traps...I made a whole bunch of acoustic panels and my rear wall is covered with homemade sky line diffusers.They are blue until the weather warms up and I can paint them out side.The only problem with two ch. audio is using a parametric to rid bass modes.Subs are sooooo much easier to work with.And Home theater with one sub is a sinch.All this is great advice.
Where to start with room acoustics
I just moved into a new house that has a listening room (13 ft x 27ft with 8 1/2 ft ceiling). It is obvious the room needs some help. I have read some of the chapters in Master Handbook of Acoustics by Everest (although some of it is over my head). The question is how to assess the needs for this room. Where should I start?
