You have stated that you use 38 traps in your living room. How big is each trap? Does a trap that goes from floor to ceiling in a corner count as a single trap or a combination of several?
For 1st reflection absorption in a home theater, you seem to recommend 2" rigid fiberglass. Dennis Erskine seems to recommend 1" on the grounds that 2" may be too deadening. Have I understood your position accurately? What is appropriate thickness for side reflection? This is where the art takes over from the science
perhaps. Or perhaps, your personal preference for a music listening room vice Dennis' for home theaters dictate different treatments? For example, you are no fan of dipole surrounds, but I am sure that Dennis would not want a good home theater without them.
My planned theater is rectangular (28' deep, 18' wide at screen, 16' wide at rear row, and 8.5' high ceilings) with a carpet floor. I will follow your advice on traps and 1st reflection treatment. Should I consider ceiling reflection absorption as well if my floor will be carpeted? (For what it is worth, I plan to use Atlantic Technology speakers and the manufacturer tells me that their 8200 THX model is designed to not have much significant vertical dispersion (ie. towards the ceiling))
Also, given my 28' long room, I am planning on putting a sub towards the rear vice front to put it closer to the listening position for greater effect. (I'll bass trap all corners). Is rear positioning OK or is the front preferred? Putting it in the front would mean requiring more power to drive it I think. Closer to seating would require less.
