Remember QRDdude?
They had some great diy examples for diffusor panels. There was also a site that showed how much larger your room would "sound" with each panel. I recall the deeper the slats the lower frequency diffusion capability.
Cool stuff.
Diffuser Panels/Room Treatment Question
How much SQ improvement would a large area of front wall chock-full of wall mounted knick-knacks and small collectibles in shallow (3-4”) shelves provide compared to a similar front wall area outfitted with dedicated sound diffuser panels? Would it be a worthwhile endeavor strictly from a room treatment perspective? I got tons of antique tools, coffee cans full of bolts, cologne bottles from the Age of Aquarius to Disco, and a bunch of other stuff that could go up on such a wall space.
Thanks in advance…
