Alan, In a response to Robert Strasser you said, "The panels you put on the wall are not a bad idea, but realize that they are only soaking up a few sabines, and probably at about 250 hz and up. Mid (125 hz & up) & high frequencies are absorbed perfectly by 4" of 3 lbs per cubic foot mineral wool. ( 4 or 5 lb soaks up a little more near the bottom of those frequencies, which might be better for DC noise.)" I just received an Oneida V3000 and it too is going in a corner of my shop. I would like to do everything I can to post the sound. I can completely wall the corner with rockwool. Roxul sells a "Rockboard" which at their specification of Rockboard 40 they say is appropriate for shops, at Rockboard 60 they say it is appropriate for sound studios. They have Rockboard 80. Any comments? Also, do you have any furtherer suggestions than what was discussed in the post by and responses to Robert Strasser? Thank you, John Neel
