RE: It's the room, stoopid!

Posted by BDP24 on March 18, 2017 at 01:18:50:
What the heck is "rockwool"? Is that slang for a type of material, or an actual product name? I just bought a bag of a dozen pieces of 15" x 48" Roxul Safe 'n' Sound with which to make some absorptive wall panels (not bass traps). It's not a semi-rigid or stiff board (like OC 703), but a soft and loose felt-like "pad", 3" thick. I'm planning on making the panels two pieces of S'n'S thick---6", for the wall directly behind my listening chair, which has to be very close to the wall---like 1' away. The rest of the room has the ASC Tube Traps (9", 11", 16") floor-to-ceiling in all four corners, but no other acoustic treatment. The rooms walls are lined with LP's, CD's and books, all in wooden racks. All my loudspeakers are dipole planars (5' out from the wall behind them), and I like the rear wave to be diffused, not absorbed. Is the Roxul a good choice to use for absorption panels placed against a wall?
