That might be the smart move to make, I was just reading an ad at A'gon for a set of floorstanding Merlins(I think) that had ERS lined inside, a factory upgrade option no less! Word's being around.

Myself on my 4 Lorelei's, I cut a 2 1/2" circle of adhesive-backed ERS and punched a 3/4" hole in the center, then took off the WBT bearing screw an placed the ERS around the plastic ring so's not to be touching any metal. There's no way I'm going inside the units. (I hope?) These 4 Lorelei's are sounding incredibly deep btw, makes me wonder how the RoomPak will effect my spacious 10' well-like soundstage? It's not that I'm not in 7th heaven now with what I have but YOU made me want more with your room treatment rants.

Thanks.
