(i'll let m0k3 figure it all out first )...
always a solid strategy! though what does Sarge think of wall treatments?
They're all out of whack now, because she retook the room,..... but prior to that, she'd made some hanging tapestries out of a tapestry fabric (of her choice) and batting; and they were really quite functional at first (before the retaking of the room). They're thicker than a normal tapestry, and have a better WAF rating than thick monotonish wall stuff (baffles).
Beyond that, we have not done much sound tuning.
I've got about a million things that I'd like to do before sound baffling / room tuning (like buying a large enough house with a space that I can dedicate to audio ecstasy).
