Plan view

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 13.7 m wall a Absen A2 Pro wall runs 21 x 8 (3528 x 1344 px, 1,680 kg, 31.1 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, Grand B holds about 184 theater seats, 75 banquet seats at rounds of 10, or 51 classroom seats. Back row in theater is roughly 6.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
