Just need two pieces of unistrut, lag bolts and washers to attach the unistrut to the joists and a Chief CMS390. You will also need a couple bolts and spring nuts to fasten the CMS390 to the unistrut. The center to center spacing for the unistrut is spaced 16" center to center.

Unistrut: https://www.lowes.com/pd/Superstrut-1-5-8-in-x-1-5-8-in-Gold-Galvanized-Half-Slot-Channel-Strut/1000182121

Lag bolts: https://www.lowes.com/pd/Hillman-3-8-in-x-3-in-Silver-Zinc-Plated-Hex-Head-Interior-Lag-Screw/1000381807

3/8" washers: https://www.lowes.com/pd/Hillman-3-8-in-Zinc-Plated-Standard-SAE-Flat-Washer/3058561

Spring nuts: https://www.lowes.com/pd/Superstrut-3-8-in-Straight-Strut-Nut/3284278

You will need two 3/8" x 1" hex head bolts, flat washer, lock washer and nut to attache the CMS390 to the unistrut.

Hi Mike

Can you share some of your build of your baffle wall?

Hi Mike

Can you share some of your build of your baffle wall?
I have a thread on the other forum and it had several pictures, but it looks like the forum change wiped them out. :(  I used 2x4's to build the wall, but double and tripled the studs, so that it is very stiff. Also have two beams behind the studs to stiffen everything up. The right and left main are angled so that speakers are aimed at main listening position. Studs are covered with 3/4" MDF. Everything is screwed together, no nails used. I did not want squeaks or rattles. I have the LCR';s and two 18" subs in the baffle wall. Speakers and subs in the baffle wall are sealed, not ported.

With baffle wall you want speakers flush and no gap between the opening and the speaker.

what did you use to make sure there was no gap there?
did you ever have a setup in your space without the Baffle?  if so did you notice a big improvement from non baffle
sorry for all the Q's

Don't forget, I designed and built my LCR's. I did something different than I have seen anyone else do. Most people try to cut a tight opening and then fill the gap. What I did that was different, the front baffle is made with an inner baffle of MDO plywood with a second layer of MDF. The MDF layer was cut 3" bigger than the out to out size of the speaker box. That gave me a flange all around the box, that was used to secure the box to the framing of the baffle wall. 

On each side of the opening in the framing for the speakers, I have four studs and those studs are only 60" in length, fit between two wood beams. This makes the baffle wall very stiff and rigid. After the three speaker boxes and two subwoofer boxes were placed in the baffle wall framing, I just filled in the space between and above and below the speakers and subs with 3/4" MDF. I also stuffed the cavity with fiberglass insulation, though with as big as the speakers and subs are, there was not a lot of open cavity.

My new screen is scheduled to be delivered this Thursday. Ordered in March, so it has been a long wait. Hopefully it happens Thursday. :) 
As a reminder, I ordered the Screen Excellence Trim L-110.

For what it’s worth, I hung pink fluffy (well, technically it was yellow because a friend of mine does commercial insulation) behind my false wall and didn’t see any measurable improvement in either the time or frequency domain using REW. My room was also very susceptible to slap echo but this required traps in the ceiling to side wall corners. Also, don’t “stuff” because it loses its properties when compressed. I made sacks using leftover GOM material and then hung the sacks in the open cavities between the subs and speakers (note: mains and additional insulation are not shown in this pic):

Masking system and screen have been pulled down. Need to remove the blocking and install new blocking, where needed for the new screen.
