Last night I put together the first two panels for my bedroom studio based on Ethan's design for Mid-bass panels. One panel is 4/8 with 2" OC 703 in it and will be mounted on a wall. The second panel is 4x8 with 4" of OC 705 and will bridge a corner for bass trapping. Just wilt the two panels in the room there is a noticable positive difference in the "sound" of the room. I can't wait to get the rest of them done and installedn I took a bunch of photos so I thought I'd share for those like me who get a lot more from a photo. Choosing only 6 photos to tell the story was challenging.
Parts for one mid-bass panel:
(3) 1x4x8' Pine boards $ 5.96 (Home Depot)
(2) 2'x4'x2" Pwens Corning 703 panels $ 27.70 (SPI Dallas)
~3yds of tan burlap @$1.48/yd $ 4.44 (walmart)
small pieces of 2x2 wood $ 0.00 (found in garage)
Staples, nails and screws $ 0.00 (also found in garage)
Total cost for mid bass panel $38.10
Total cost for corner bass trap panel (4 panels of OC705) $ 111.12
The only real difference between the thick & thin panels is the thich panel has two layers (4") of 705. Therefore the 2x2 blocks are not needed. Instead, I streched a couple of strips of burlap across the back to keep the pieces from falling out the back side.
Each frame took me about 30 minutes to complete. I used a hammer, hand saw, drill and a staple gun for tools.
Photo 1 - The competed frame with the fiber panels inside. I actually just laid the 8 foot sections against the two pieces and trimmed the ends to fit and nailed them on with some finishing nails. I'll probably use screws for the next panels.
Photo 2 - After the frame was finished I attached the 2x2 blocks to keep the fiber from falling out the back. I used screws for this.
Photo 3 - Here is the frams with all the 2x2 blocks installed.
Photo 4 - After the blocks were installed, I turned the frame over to install the burlap.
Photo 5 - Stapeling the burlap. The burlap came folded in half on a bolt. It was exactly wide enough to stretch around the frame width without trimming. The only cutting was the length.
Photo 6 - Here is the corner panel in the studio. I have 9 foot high ceilings. The panel is simply resting on the floor bridging the corner. The midbass panels will be hung on the walls around the room and possibly a couple from the ceiling.
Enjoy
