Quick n' Dirty Baffles

After I finish my riser project, I'm going to have a bunch of 705 and 703 left over, plus some MDF. Thought I'd make some 2' x 4' baffles with the scraps. These will be used mostly to seperate acoustic players - say a couple acoustic guitarists, a stand-up bass player, and a brush drum kit - in a 21' x 23' room. Fyi, the room is treated with several 705 corner bass traps and 703 wall panel mid/hi absorbers (plus a cherry laminate floor with misc. area rugs). Here's what I'm planning to build; I'm wondering if this will be effective for the above purpose: 1. Make a 2' x 4' frame from 1 x 6's. 2. Sandwich the following inside the frame (listed as they would be installed in the frame, from front to back): - 2" thick 2' x 4' 705 panel (covered in burlap) - 1" air space - 1/2" thick 2' x 4' MDF panel - 2" thick 2' x 4' 703 panel (covered in burlap) One other thing... I know some baffles have one absorbing side, and one reflective side. I want both sides to be absorbing, at least for now. Thoughts? Adam

AjD, That will work fine. I just did a very similar thing but they were 1800mm x 900mm. They got a bit heavy so I put wheels on them. These ones also had windows as they were for a group of voice over artists who wanted to work in a circle. Andrew

Andrew: Those look great! Andre
