Richard Green room tune?


Has anyone used the freestanding Richard Green room tune or tune packs acoustical treatements? To what results? I'm looking to tame the brightness in my 11 x 15 room.

Not to be fussy but did you mean Michael Green? I'm using Corner Tunes and 4 48" Room Tunes IMO I 've been very happy with the results and wouldn't be without them.
