LED wall that fits

Under a 10.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 17 rows of 500 mm tile flown. Along the 81.4 m wall a Absen A2 Pro wall runs 130 x 17 (21840 x 2856 px, 22,100 kg, 408.9 kW).

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, Hall B holds about 9,454 theater seats, 3,867 banquet seats at rounds of 10, or 2,659 classroom seats. Back row in theater is roughly 74.4 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
