Has anyone experimented with the acoustic effect of staining hardwood walls of a listening room with polyurethane stain or sealant?
Does polyurethane add sound reflectivity to the wood walls? Does polyurethane stain or sealant have any sonic effect at all versus not applying polyurethane to wood listening room walls?
