Home-made Acoustic Panels

[WineOfTheVeins]

Hello all. I am in the midst of making my own acoustic panels. I've finished one, with some minor kinks that will be ironed out for the other 3. I show you exactly how I did mine in hopes it will help others tackle this project and enhance their room's acoustic properties. After a lot of time in a hardware store and a tape measure, I decided against nominal sized lumber and went with 3/4 MDF, and am using 16" OC Roxul Safe n' Sound 3". This insulation holds quite an impressive spec sheet compared to most other insulations. My finished product came out 15 3/4 wide and 47 3/8 long, tightly nestling the batt of insulation with no overhang, bulging, or sloppiness. The frame is rock solid to boot. Still need to wrap it tightly in a dark fabric. I'll upload pictures of the finished product as well as the steps if people are interested.
I want to make the Focals shine.

I am interested in the panel design that you are making. I do have my 16 x 35 room finished for music and movies. But lack design for my surrounding walls. I’m a huge fan of Focal since I’ve visit a local stereo store that sells them.

Make sure its the correct fabric! The Guillford of Maine is most recommended due to availability, but the key is you need to be able to blow through the fabric and feel it on the other side. The function being that some of the sound energy is converted to heat through friction.

I have 4 panels almost completed. I was tied up and haven't been able to touch them until now. I will upload pictures and instructions on the weekend. I must say MDF was a good choice, especially if you measure twice and cut once. If done correctly, they are rock solid, hold a batt of safe n' sound snug with no bulging or overhang. I haven't chosen the fabric yet, but I did use fiberglass mesh stapled on the front and back before the fabric step.

Thanks TheWarrior. I'll keep that in mind. I guess if you can breathe through it easily, it is a good material.
