LED wall that fits

Under a 3.3 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 17.6 m wall a Absen PL2.5 Plus V2 wall runs 28 x 2 (5600 x 400 px, 437 kg, 9 kW).

Panel	Pitch	Wall (cols x rows)	Size	Resolution	Weight	Power (max)
Absen KLCOB 0.78	0.78 mm	23 x 4 = 92	13.8 x 1.4 m	17664 x 1728	414 kg / 913 lb	8.1 kW, 39 A @ 208 V
Absen PL2.5 Plus V2	2.5 mm	28 x 2 = 56	14 x 1 m	5600 x 400	437 kg / 963 lb	9 kW, 43 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, Salon Gretry holds about 349 theater seats, 142 banquet seats at rounds of 10, or 98 classroom seats. Back row in theater is roughly 10.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
