Under a 3.6 m ceiling with 1.5 m trim and 0.3 m clearance you get 3 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 17.3 m wall a Absen PL2.5 Plus V2 wall runs 27 x 3 (5400 x 600 px, 632 kg, 13 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, E258 holds about 378 theater seats, 154 banquet seats at rounds of 10, or 106 classroom seats. Back row in theater is roughly 10.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
