Acoustic panels

Have any of you made simple acoustic panels from wood frames, sponge or insulation guts and fabric outer? Thoughts on their performance vs professionally made?
Thanks all.

    I made some for my son's studio. Use Rockwool for sound absorption. For covering, we just got some course weave material from the local fabric store. They work very well. Sometimes I borrow them to put on the walls beside my LSi15's and I'm amazed how the sound stage opens up.

    I've made several. They work very well and aren't eyesores like traditional wall treatments which I ended up taking down in favor of them. I used 2'' square wood for the frame the size of the beach or bath towel I was using and used foam acoustic panels cut to size underneath.

    I bought mine from, https://www.soundproofcow.com/product-category/acoustic-panels/fabric-wrapped-acoustic-panels/

    It was the easiest way for me. They look nice and work well.

    If you search the title of your thread in the forum you’ll find a number of member threads on DIY and professional treatments. You can even see mine from 2013 when I made some ‘portable’ ones.

    I have been very happy with my DIY panels.

    You have access to nice WAF fabrics so DIY can look great and match your decor. I just went with GIK myself. If you want art panels, you can upload a pic of yours or choose from many they offer.

    I had recovered some GIK panels that had the base burlap type covering with Guilford of Maine acoustic fabric. Wife liked Silver Papier. I ordered GIK bass traps to match.

    This is one source for GIK fabric.

    If you are interested in DIY... At the time I built mine, this was the cheapest place I could find to order OC703. It's the shipping cost that gets you. Not sure if they are still the cheapest, I haven't price checked in a long time.

    https://www.buyinsulationproductstore.com/

    They also carry Guilford of Maine (acoustic transparent) fabric that comes in wider widths than most other fabrics. But I went the cheaper route and used fabric from Joann Fabrics. They have a coupon page:

    https://www.joann.com/coupon/

    You want breathable fabric (loose weave). Tight, none breathable fabric can, in theory, reflect highs instead of absorb them. A none-issue for bass traps. For best absorption you want an air gap between the insulation and wall.

    Also keep an eye out on Craigslist. I purchased six 2" thick panels already built on CL and disassembled them to make 4" panels. Then later found two leftover full boxes from a project, of 4" thick OC703 from ATS that I bought for dirt cheap on CL.

    I traded my SRS 2 for a complete acoustic treatment for my small humble room. Guy came up from Miami did several messument with some mic's and a PC. Placed 9 Owens Corning 1 inch glass fiber and two bass traps. I added 4 more corner bass traps later.

    Before I made this deal I was going to go with Roxul. Here is one of the videos I liked for the DIY.



    You can use the same stuff for some acoustic panels.

    I purchased 4 * 24x48x2 panels from acoustimac... Only 250 shipped with the executive cloth and cornings insulation

    They are not as nicely built as GIK but just as effective. I am pleased with the results. I store mine when not using the 2 channel rig.

    I'm still an NBP dealer but personally I've fallen out of love with the wall approach. It has its merits but the mobile treatments are more where I lean to now. The tuning abilities they allow for are impossible to beat.

    Also, don't stick strictly to absorption. Diffraction is a powerful tool too - just as powerful as absorption and twice as good when used together properly.

    You know those crystals and doodads people put on the wall? The reason they do anything for your system is they introduce new resonances into the air. They are quite elementary if you think about it and not the voodoo so many people claim them to be. How much they actually impact the sound depends on how strong the resonances are. Keep this in mind if you add something to the room.

    Just added an 8x10 wool rug to my seating area (Hand me down from the wife). I ageed to this grudgingly as I knew it would make the room too dead.
