LED wall that fits
Under a 3.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 2 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 15.8 m wall a Absen PL2.5 Plus V2 wall runs 25 x 2 (5000 x 400 px, 390 kg, 8 kW).

|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 21 x 3 = 63 | 12.6 x 1 m | 16128 x 1296 | 284 kg / 625 lb | 5.6 kW, 27 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 25 x 2 = 50 | 12.5 x 1 m | 5000 x 400 | 390 kg / 860 lb | 8 kW, 38 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, Park Ballroom holds about 16 theater seats, 6 banquet seats at rounds of 10, or 4 classroom seats. Back row in theater is roughly 8.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
