SO just to update my ongoing acoustic treatment implementation and development.
Here you will see finally the finished three QRD stack made up of two units purchased from RPG and a custom bottom larger QRD. It ended up being 9ft and 6 inches tall!!!! Let me say, me and my wife lifted the top two QRD section with the added Period wings and it was about 60+ lbs alone onto the bottom QRD and wedged it between the two stabilization brackets on the sides. Once we lifted it I really didn't think we were going to be able to do it and I suddenly had immediate visions of a trip to the emergency room as this thing was heavy and if it fell we would be at the hospital for sure. None the less it is done. The back section is 6 inch thick Broad band absorption panels.

OK, so here are the purchased Skyline Primitive Root diffusers purchased from SoundArt. They were kind of yellowish in the original state. I began to spray finish these with white primer, must be water based, which I prefer for clean up reasons. Well, as many have mentioned these type of diffusers just suck up paint and finish. This after 5-6 coats of sprayed white primer. I will apply another 5-6 coats looks like, whew. Even with my new hi volume low pressure spray machine, this takes lots of time and paint!! Getting close and still debating painting them black or just keeping them white, but they will be mounted into stained wood frames.
Next are SIX Auralex T-Fusers. They were WHITE originally and now they are STILL WHITE, but this is an oil based primer, they I sprayed on very light coats. It looks really nice and flat. I will paint these flat black next.

OK, so this is for those who like MDF finishing and pure wood staining.
First is the raw cut sanded MDF boards that will be the 4'x10"x.5" WINGS for the QRD. You can see them go from light brown to three coats of white primer, with sanding in between. This was a lot of work, but it is not easy to get MDF nice and smooth on the cut edges. I used oil based primer, can't be water based. Then I sprayed a water based Black flat paint, but was learning how to use my new paint machine, so it was thick and had to brush it. This is just the first coat, but already looks pretty good. I will apply one more to all sides.

Last is the outer frame of the QRDs, which will be stained Spruce.
You can see the first coat of miniwax golden oak stain. and the finished second coat.

Thats all for now, but I promise next time I will have at least one of the FOUR huge 4'x2'x10" black and stained wood QRDs done, finish the Q-fusers, and also be done with the Skyline PRDs. So there will be more finished products to look at!!!!!
