Absen KLCOB 0.78	0.78 mm	88 x 6 = 528	52.8 x 2 m	67584 x 2592	2,376 kg / 5,238 lb	46.7 kW, 225 A @ 208 V
Absen PL2.5 Plus V2	2.5 mm	106 x 4 = 424	53 x 2 m	21200 x 800	3,307 kg / 7,291 lb	67.8 kW, 326 A @ 208 V

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.

Seating estimate

After a 12 x 7 m stage, Gallery 1 holds about 803 theater seats, 328 banquet seats at rounds of 10, or 226 classroom seats. Back row in theater is roughly 59.5 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
