Hey everyone. The wife and I recently bought our first house. In the initial walkthrough I quickly identified which room would be mine, but there was a problem - it was so echoey. It has bamboo floors, plain walls, and huge windows. I figured as soon as I moved in and put in a couch, desk, rug, etc. it would go away. Well, it didn't. My inspiration came from this thread: http://www.avsforum.com/forum/19-de...inted-movie-poster-acoustic-panels-cheap.html Basically, I ordered 13 custom printed cloths from https://www.spoonflower.com/ The 3 Lord of the Rings posters, a map of Middle Earth, a Star Wars poster, a Dark Souls 1 map, and 7 images of galaxies (mostly for the ceiling). I ordered the "Performance Knit" fabric from Spoonflower. It's a very light fabric, and somewhat stretchy. Some movie posters were acquired here: http://forum.blu-ray.com/showthread.php?t=220892 - other designs were simply found on a Google image search. I tried to work with the largest resolution images I could find, and then used Gimp to scale them to fit the panel size. I have a mix of 36"x24" and 48"x24" panels (actually slightly bigger when you account for board thickness). For the frames, I simply went to Home Depot and got a couple SUV loads of these furring strips: http://www.homedepot.com/p/1-in-x-3-in-x-8-ft-Furring-Strip-Board-164704/100094214 . And a couple nails per side to hold the boards together. I then used some heavy duty picture wire to hang the wall mounted panels. For the ceiling mounted ones, I screwed 4 eye hooks per panel into the studs in the ceiling. I found it too difficult to match up 4 with 4, so on the panels themselves, I only have 2 eye hooks on the bottom half. On the top halves, I have little loops of picture wire. This gave me some wiggle room to make sure my panels could hook up with all 4 of the eye hooks in the ceiling. An a related note- because I used eye hooks, the ceiling panels aren't perfectly flush. They hang down ever so slightly. I hear this makes them more effective over a wider spectrum? Don't quote me on that. After assembling all of the wood frames, we wrapped the back sides in a simple burlap. Nothing fancy. Just something to hold the insulation in. Speaking of insulation... the acoustic panels I made from Roxul Rockboard 80. I ended up using 12 sheets of it (so two packs). I also made 3 bass traps, for which I used (2x) packages of Roxul Safe 'n' Sound. Nice thing about that was that I could just pick it up from Home Depot. The Rockboard 80 was kind of annoying in that I simply could not find a local supplier. The bass traps are simply a 1 foot square frame wrapped in fabric. I cut the Safe n Sound into 1 foot square pieces and stacked them up from floor to ceiling in the back two corners of the room. I also have another one laying down across the bottom of the room, behind the couch. I think I need to make some more of these later, just not sure where to put them. Perhaps I could stack some more on top of the one that is laying down back there. With the layout of my room, I can't really put any in the front corners. Now, none of the stuff I make is professional quality. But it's good enough for me, especially if it works right. And do these ever. I get like a recording studio vibe when I come in to this room. It's my first experience with a treated home theater and I really like it. No more echo! Anyway, some photos: My dog Sif, figuring out where she needs to go to get the ring to Mordor: Example of the printed cloths: Built frames having the burlap put on to the back and then filled with Rockboard. The stuff isn't nearly as bad as I hear fiberglass is, but we still wore gloves and respirators when working with it. Any skin that touched it was left itchy and irritated. Could have done a better job wrapping the fabric. Also, the first batch of cloth I ordered I left with a white background. If I had to do it again, I would make everything have a black background to hide things better. Ceiling mounting was a pain in the butt! Black backgrounds are the best backgrounds. Actually, on the star pattern prints I simply chose the option on Spoonflower to "repeat" the image to fill the entire cloth. You can see a corner bass trap behind one of my Minimartysubs, and some 3" acoustic foam panels I put up on the back wall. Definitely won't need any more mid-high frequency panels, but could probably use more bass traps. Also, more subwoofers. Aaaand I need to upgrade to 7.1 or even Atmos soon as well. And upgrade my center. After I build a sliding barn door for the room. And a bedframe, and, and... lol. Thanks for looking.
