Richard Green room tune?

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.

I did mean Michael not Richard...thanks....

I've used the corner tunes for years in numerous rooms with excellent results.

well, for anybody that like violins check out RICHARD Greene....

I've made a diy version and it works. So, I would assume the real ones do too. Eighth Nerve does the same thing, and they've said that they haven't had a single return.
For the difference that it made for me, I believe it.

I'm kind of worried about the brightness in your small room though. I had that in a room for about a year and never solved it. I could absorb the room, but it would sound dead. The room tunes weren't enough to deal with it. Hopefully, others can chime in.
