Plan view

LED wall that fits

Under a 3 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 17.4 m wall a Absen A2 Pro wall runs 27 x 2 (4536 x 336 px, 540 kg, 10 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, Ontario Foyer holds about 393 theater seats, 160 banquet seats at rounds of 10, or 110 classroom seats. Back row in theater is roughly 10.4 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
