I simply bought 2" thick Owens Corning 703 panels (2'x4'), made 2'x6' wooden frames with 1x2, stuffed 6' worth of panel in each frame, shot nails thru the frames to hold the panels in place, covered the panels with fabric, and hung them from the ceiling using eye bolts and metal tackle from the hardware store. Worked great, reduced slap echo alot, looks good (similar color as ceiling), cost less than $100 for the whole shebang! You just need to find a source of 703, and I think the minimum you can buy is a box of 6. Good luck, Peter
