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 15.2 m wall a Absen A2 Pro wall runs 24 x 2 (4032 x 336 px, 480 kg, 8.9 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, Columbus A & B holds about 60 theater seats, 24 banquet seats at rounds of 10, or 16 classroom seats. Back row in theater is roughly 8.2 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
