LED wall that fits
Under a 2.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 1 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 14.3 m wall a Absen PL2.5 Plus V2 wall runs 22 x 1 (4400 x 200 px, 172 kg, 3.5 kW).

|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 19 x 2 = 38 | 11.4 x 0.7 m | 14592 x 864 | 171 kg / 377 lb | 3.4 kW, 16 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 22 x 1 = 22 | 11 x 0.5 m | 4400 x 200 | 172 kg / 378 lb | 3.5 kW, 17 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, River Room BC holds about 92 theater seats, 37 banquet seats at rounds of 10, or 26 classroom seats. Back row in theater is roughly 7.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
