Plan view

LED wall that fits

Under a 3.2 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 12.5 m wall a Absen A2 Pro wall runs 20 x 2 (3360 x 336 px, 400 kg, 7.4 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, Franklin 12 holds about 66 theater seats, 27 banquet seats at rounds of 10, or 18 classroom seats. Back row in theater is roughly 5.5 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
