An absorption cloud design

It is an Owens Corning product that comes in 4' x 2' semi-rigid panels and is made of densely packed glass fibers.

Just recently found this forum. I'm loving it too. Please excuse my newbness but what exactly is the purpose of this cool thing? Could someone explain? Thanks.

A slight variation on Davids cloud. I added a little window and now I can fold one side down and use the cloud as a gobo! Thanks for the great idea David.

If you look closely your can see a 2 panel 4'x4' version very similar to Davids hanging over the drum kit. It really made a big difference in how the kit sounds in the room and when recorded. The cymbals are much more tame and articulate.

The window can be arranged for short and tall singers or to one side or the other for standing guitar slinger singers.

And of course it still works as a ceiling cloud.

I used the angle metal (seems like some kind of pot iron recycled wonder metal alloy that is optimized for low cost) intended for suspending acoustic ceiling tiles. I bought it at Home Depot in the section where they sell the acoustic ceiling tiles. Here is a picture of the sku from one of the twelve foot sections. I paid around $3.50 per section.

The cloud over the drum kit has only one side which faces down and holds the 2" corning 703 panels in place. The gobo version with the window has a top and bottom piece to keep the panels captive when used as a gobo.

The metal seems flimsey until it is rivited together. I cut it off with a carbide blade on my radial arm saw, then trimmed it using a 4.5" angle grinder with a metal composite blade. On some of the edges I used the angle grinder to leave a long tab to either bend over for more strength or space the top and bottom pieces together. The corners are made from quarter inch thick 1.5x1.5" angle aluminum with an eyelet bolted into the middle. The angle aluminum is pop rivited to the corners. I also put eyelet less corner pieces around the plexiglass window to hold the center together.

Phil, that's a really cool multi-purpose "cloud-bo" (for lack of a cooler name :=) thanks...
