I'm doing my first DIY acoustic treatment - also my first 7.1 system.
I'm reading the Master Handbook of Acoustics and I've read lots of website pages - very enlightening, but I'm still a beginner.
My basement room is small (15 X 11 X 7'4), with fairly ridgid side walls, and a front wall half covered (upper half) with heavy mirror (I haven't decided how to cover the mirror, yet). There's just eough room for a comfy couch, a wooden coffee table, CD rack, and the 7.1 system with a Sammy HLR 4667 and two subs.
I'm already constructing triangular, floor-to-ceiling corner traps. Their 16x16x22 footprint is fully filled with layers of OC703 and wrapped in black poly batting and burlap. I plan to hold these freestanding units out from the walls by 2". I'm also building two 43" long corner units I plan to center on the front and rear walls, where the wall meets the ceiling.
The next step will be the freestanding, side-wall panels. The question is -would 6' tall panels would be a more effective size, than the 4' panels I see on the DIY and commercial supplier's websites?
I was planning to use a pair of absorbers on each side wall, at each main speaker reflection point. Are the reflections above and below the shorter panels of little concern OR could it be that the area of larger panels would overwhelm the liveliness of the room OR is the cost to high for a small benefit?
I can easily build 4" thick (by 2x6') OC703 absorbers OR 6x3' polycylindricals (using 1/8" luan door skins with a 703 back pad).
I'd appreciate your input to help me make the best choice possible...
Thanks... Hermit
