Plan view

Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.

LED wall that fits

Under a 3.7 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 14.6 m wall a Absen A2 Pro wall runs 23 x 3 (3864 x 504 px, 690 kg, 12.8 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, Rosemont Foyer holds about 287 theater seats, 117 banquet seats at rounds of 10, or 80 classroom seats. Back row in theater is roughly 7.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
