Here are the panels I built. Six and a half inches of fiberglass and 2 inches of rockwool. A set of these made a greater difference in my listening room than any component upgrade.
If you PM me, I'll send you drawings outlining the construction.

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?

I don't typically frequent the Tweaker's Asylum, but thought I'd see what's here, and so I just came across this thread from 2016. TWENTY-SIXTEEN. Is this a joke? Egg cartons? Seriously?!Can somebody please post the acoustical characteristics of egg cartons mounted on walls? 'Cause I'm sure some budding garage band or hifi enthusiast from the 1960s or 70s will be interested. Oh, wait... This isn't 1970 anymore!
After 8 jillion articles in Audio, Stereo Review, TAS and Stereophile, and numerous books written on the topic of acoustical characteristics of various materials and mounting methods, and innumerable measurements done by ASTM, manufacturers and others over the past seven decades, there actually are people who still ask about egg cartons as an acoustical treatment?
Further, the OP didn't specify if he was asking about the old style cardboard pulp cartons or the newer foam type - I'd guess there is a difference! LOL
Seriously?
:)
