Acoustic Panel Remix

Saw the original post by @TorbenJ, and wanted to make some slight changes, that all tie in together.

First off, I added a small standoff onto the back of the piece. This will allow sound waves to reverb off the wall at angles, and become trapped inside the materials inside the panel, rather than bouncing off the sides of the panel and back into the room.

Next, I removed the cut in on the back for a hard plate, as this also stops sound transmission through the rear of the panel. Instead, I recommend either finer woven burlap fabric, or a lower thread cotton as a backer.

One version has the rear pin already attached, the other has an a hole for a future pin to be added, which has also been included in another model.
