Hi Randy-11,
By placing the HRS platforms on a wood surface that is intended to "resonate" versus "isolate," the midrange sounded as though it had a film covering it.
That is why I'm trying to determine if a solid wood surface, like the one that maxboy00 suggests, will solve this issue.
From what I've been researching, it seems that maple and mahogany are the preferred hardwoods for isolation.
