| DIY bass traps and absorbers
I was shown and found some info on creating your own absorbers and bass traps using OC 703 rigid fiber.
They recommend using 2 layers to get 4".
I was wondering if there'd be any loss of effectiveness or gain in effectiveness if I use 13" R-38.
Would that extend the absorption to lower frequencies?
Would these be good for putting in the corner for low frequency absorption?
I assume if I space them from the wall it allow double absorption of extended freq's from the direct sound and first reflections.
I need a cheap and effective full freq. treatment.
Any advice is welcome.
