Chris, it's not as important if those side walls/windows are splayed enough to redirect the sound to the rear of the room where it can be absorbed (small room) or diffused (large room) - but you're right, if those surfaces are parallel and NOT absorbent it would be bad... Steve
Ahh I see it's in the angles...so would postioning a mirror there angling it until you can't see your speaker be the way to determine how much of angle you need? Thnks, Chris
That would sorta work, except that when designing an actual Reflection Free Zone room, you ideally would have a big enough RFZ so that others could be in it too. If you were fortunate enough to have actual Ray Tracing software and know how to use it, that's the best way to set angles. Without that, the method I use is a Cad program that you can set the "ortho" angle to whatever you want, and draw several rays from each speaker center, each one at maybe 5 degrees from the last, then where those rays intersect walls I measure the incident angle, match that with a reflective angle, and continue each ray until its path is at least 22 feet long or it impinges on the desired RFZ area. If the ray gets back to the RFZ area in less than 22 feet travel, I change the angle of one of the wall sections (keepin in mind things like symmetry) It's kind of a pain-staking process that way, but eventually you can get angles where they work for everything. (I'm still working on accomplishing that for a surround room, however...) Steve
My space is almost identical in size. John designed the layout - below. Just got finished on the 2 layers of 5/8 on RC-1 on the ceiling - took 3 weekends and a lot of aching body parts - glad that part is done!

Hi John and everyone. Well I took the back half of my control room ceiling down -- what a mess.haha. I'd thought I'd start with the rear wall first before attempting the soffit monitor front wall. Having seen LDQ's (Silva productions) control room (greta pictures LDQ - I hope we can get in touch), I wonder if I would benefit from some hanging panels there -- however, I can only go as deep as 16"? Too shallow for a back wall John? Maybe 8" of 703 instead? Do you think panels would work better than 8" 0f 703? As for the rear half of the control room ceiling, how much 703 would you put in there? Best, Dave Blauvelt Bluefield Studio

16" is enough for a hanger series IMO. cheers john
Here's an update of the soffit plans for anybody interested. I'm still working on the back wall. Dave

I should mention that at John's suggestion, the console's placement has moved closer to the soffit wall, reducing rear console reflections and should help with console control reflections as well -- which means that I will be attempting a custom "fit" of sorts -- building a soffit wall that the console slides into. :shock: Dave
