What are you planning to use inside the cabinet, damping wise?
I found a combination of real wool felt (5 to 7mm thickness) on all walls plus fiberglass insulation in the center of the enclosure worked better than each material on it's own.
I made a test enclosure and used impedance measurements to find my ideal recipe.

I've had good luck with this combo so I was planning on sticking with it.
For the walls:
Sonic Barrier 1/2" Acoustic Sound Damping Foam with PSA 18" x 24"
For the stuffing:
Acousta-Stuf Polyfill Speaker Cabinet Damping Material 5 lb. Bag

Awesome build and an excellent choice for the driver!
I'm really looking forward to seeing how these turn out.
Two notes:
1 - I'm really glad you pushed the C-C spacing and tolerance to get all 36 drivers in. It might mean a bit of extra effort getting everything mounted, but it will be worth it. I also pushed the C-C spacing on my TC9 build too close (I literally mounted them frame to frame with no tolerance) and I ended up having to lightly sand the touching ends of each driver's plastic frame to get everything to fit
2. You chose the correct wiring method for this speaker, and don't let anyone dissuade you from this. The 6 parallel drivers in each sealed enclosure is far more important than any other factor mentioned previously in this thread. Stick with it!
Thanks for documenting all this, and I will definitely be following along
Cheers,
Owen

Thanks for the encouragement and confirmation! I've gone through a large number of posts before arriving at these design decisions
. I think you were having a discussion in another thread regarding wiring with sims and some real life experience. Thanks to you and all the other members for having the discussions on the boards. That information has been very very helpful and has saved A LOT of grief!! As others have mentioned a bullet point sticky post for full range line arrays is in order as there is a lot of great information scattered around the forum.
Keep the suggestions coming! I'm hoping to have the enclosures ready for driver installation and wiring in 2 weeks time. Then its measurements, EQ and extensive curve tweaking lol. Getting excited.
One more for that bullet list: for every repetitive job: create a template first!
Makes life a lot easier

hehe too true!
hehe yes, not looking forward to this. Helped a friend do shorter array..........basically set aside a week a piece to do
.Partially foamed. Always more work than than estimated. Did not calculate the correct area of foam, need to order more . Thinking of picking up a 1200AS2 board for the linearrays. Interested in comparing to the horns that are setup in this room.

While I have all the quick connects, its quite hard to get the terminals on with out breaking the drivers. Even with holding the terminals with pliers I managed to break 1. Lucky I have a few extra as I've destroyed 1 in the process.
That said I solder a LOT so soldering the tabs it is. Looks like if you are quick, the frames don't melt. Will have to pay more attention when wiring but........

Thanks! On carpet they are about 1" from the ceiling. I have some new enclosures that are almost ready for the bassBins and horns. The bins will go in the corners when finished and provide sub support for the LA.
The current setup is 15TBX100 in sealed encosures and SEOS-24 horn with Radian 745BePB Xover around 600hz LR4. They sound better crossed to wide dispersion tweets at 10khz but its really hard to tell.
Good suggestion but I'm libel to put the screwdriver through my hand
