LED wall that fits
Under a 6.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 8 rows of 500 mm tile flown. Along the 18.3 m wall a Absen PL2.5 Plus V2 wall runs 29 x 8 (5800 x 1600 px, 1,810 kg, 37.1 kW).

|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 24 x 12 = 288 | 14.4 x 4.1 m | 18432 x 5184 | 1,296 kg / 2,857 lb | 25.5 kW, 123 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 29 x 8 = 232 | 14.5 x 4 m | 5800 x 1600 | 1,810 kg / 3,989 lb | 37.1 kW, 178 A @ 208 V |
| Absen PL3.9 Plus V2 | 3.9 mm | 29 x 8 = 232 | 14.5 x 4 m | 3712 x 1024 | 1,810 kg / 3,989 lb | 32.5 kW, 156 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, Grand ABC holds about 557 theater seats, 228 banquet seats at rounds of 10, or 156 classroom seats. Back row in theater is roughly 11.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
