Plan view

LED wall that fits

Under a 6.4 m ceiling with 1.5 m trim and 0.3 m clearance you get 9 rows of 500 mm tile flown. Along the 14.9 m wall a Absen A2 Pro wall runs 23 x 9 (3864 x 1512 px, 2,070 kg, 38.3 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, Key 9 holds about 157 theater seats, 64 banquet seats at rounds of 10, or 44 classroom seats. Back row in theater is roughly 7.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
