It's not as thick as my foam but it's as good as it's gonna get. Here's what I did. I bought some 1/2" thick 2'x4' sheets of Owens Corning rigid fiberglass 703. It's not very rigid by the way. It's a porous product that somewhat holds form. If you can't find any then go to Lowes and check out their drop ceiling tiles. They should have tiles made of rigid fiberglass with a plastic face on one side. It's classified as an acoustic grade ceiling tile. It has to be porous! Not the hard ceiling tile made of particle board crap. It's not porous! Now, take that to the backyard. Put on a respirator and some gloves and peel the plastic face off. Then, glue the foam to the fiberglass using liquid nails. Bear in mind it's not going to hold very well but well enough to not fall down. Just don't f*ck with it. Next, take some 2"x2" pieces of wood 4' long and glue 2 pieces together. Bear in mind a 2"x2" is actually 1.5"x1.5". Yeah, it's 2" when it's cut. It then dries and shrinks to 1.5". Now you have a 3" thick spacer. Let the glued stuff dry overnight. Screw some L brackets onto the sides of the wooden spacers and mount to the wall 1.5' apart using thick threaded dry wall grade screws....or find a stud....(enough with the Momma jokes). Now nail the absorptive panel to your wooden spacers using relatively small nails so you don't split the wood, but not so small so it rips through the foam. The more nails the sturdier it is. It's a pain in the ass but it works. Mine have been on the wall for 2 years now. There are alot of ways to float your panels. You could just build a wooden frame comprised of 2"x2" and glue the foam to the frame. In retrospect, that's what I should've done. The reason I like the 1/2" thick fiberglass panels is b/c you can stack them if you need to & make different thicknesses for deeper bass trapping. I did that on my back wall where the bass pooling is the worse. It helped.
Oh, get a reference CD with some bass. Play it in through the NS10's. Walk around the room. Listen for excessive bass pooling areas in the room. That's where you definitely want to float the traps off the wall. If it's in a corner get some corner bass trapping products. In the other areas like 1st reflection points you can probably get away with just slapping the stuff onto the walls. I floated all my panels cuz my room used to suck hot goat. |
Thanks for the help! So after i do this i should be good to go?
