LED wall that fits

Under a 2.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 1 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 20.1 m wall a Absen PL2.5 Plus V2 wall runs 32 x 1 (6400 x 200 px, 250 kg, 5.1 kW).

Panel	Pitch	Wall (cols x rows)	Size	Resolution	Weight	Power (max)
Absen KLCOB 0.78	0.78 mm	26 x 2 = 52	15.6 x 0.7 m	19968 x 864	234 kg / 516 lb	4.6 kW, 22 A @ 208 V
Absen PL2.5 Plus V2	2.5 mm	32 x 1 = 32	16 x 0.5 m	6400 x 200	250 kg / 550 lb	5.1 kW, 25 A @ 208 V
Absen PL3.9 Plus V2	3.9 mm	32 x 1 = 32	16 x 0.5 m	4096 x 128	250 kg / 550 lb	4.5 kW, 22 A @ 208 V

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, Orpheum holds about 99 theater seats, 40 banquet seats at rounds of 10, or 27 classroom seats. Back row in theater is roughly 13.1 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
