|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 27 x 17 = 459 | 16.2 x 5.7 m | 20736 x 7344 | 2,066 kg / 4,554 lb | 40.6 kW, 195 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 32 x 11 = 352 | 16 x 5.5 m | 6400 x 2200 | 2,746 kg / 6,053 lb | 56.3 kW, 271 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, The Grand Hall holds about 336 theater seats, 137 banquet seats at rounds of 10, or 94 classroom seats. Back row in theater is roughly 13.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
