Excellent theater, Mike! The baffle wall looks menacing! Is their a diy for your lcr speakers?
My side surrounds and four Atmos speakers are JBL Pro 8340: http://www.jblpro.com/pub/cinema/8340.pdf
No, not really for the speakers. I do have more pictures. Front three are DIY 3-way active using the following drivers:One Beyma TPL-150H: http://www.beyma.com/products/diapharagmtweeters/1TPL15H8Two Acoustic Elegance TD12M: http://aespeakers.com/shop/td/td12m/One Acoustic Elegance TD18H+: http://aespeakers.com/shop/td/td18h/MiniDSP 10x10HD for crossover: https://www.minidsp.com/products/minidsp-in-a-box/minidsp-10x10-hdThe 18's cover from 40hz to 200hz. The 12's cover from 200hz to 1,400hz and the Beyma is 1,400hz and up. The MTM boxes are pretty big. I do not have the exact measurements, but they are around 18 3/4" wide x 12" deep x 50" tall. The TD18H boxes are 42" wide x 23 3/4" H x 12" deep. The two TD12M's share common space. The TPL-150H has a separate enclosure inside the box. That allowed me to remove the back cup on the TPL-150H. I lined the interior of the cabinet with a damping material and then heavily stuffed the cabinet.Sounds like a lot of work! I'll just stick with my JTR's. I will build my sealed subs though.
I originally was going to go with the 8340s for all my surrounds and Atmos, but I ended up with the 8320As for the Atmos channels as I didn't like the idea of a heavy speaker over my head. I have to admit the JBLs are awesome for surround, and Atmos speakers!
They were actually pretty easy and safe to mount. The 8340's have an angled front face and they already have four threaded inserts on the back. So I cut two pieces of 5/8" light metal channel 1" longer than the width of the speaker. I then bolted the channel to the back of the speakers, so that it extended past the speaker 1/2" on each side. I then held the speaker flat against the ceiling and screwed through the channel (1/2" tabs sticking out) into blocking that I installed above the ceiling. So I safely have 40 pound Atmos speakers hanging from my ceiling.
