Plan view

LED wall that fits

Under a 5.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 7 rows of 500 mm tile flown. Along the 26.5 m wall a Absen PL2.5 Plus V2 wall runs 42 x 7 (8400 x 1400 px, 2,293 kg, 47 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, Allegheny III holds about 873 theater seats, 357 banquet seats at rounds of 10, or 245 classroom seats. Back row in theater is roughly 19.5 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
