Reading Dennis Erskine's article in HT Builder re: stage construction he notes you should use 5/16" acoustic matting when designing a stage on a wood floor. I've looked at a product called Acousti-Mat but it seems to be only sold in large rolls for whole-floor installations. What other alternatives might you suggest for decoupling a stage from a wood floor? Doesn't have to be too robust as the only speaker on the stage will be a center channel on a stand. Thanks.
