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 21.9 m wall a Absen PL2.5 Plus V2 wall runs 35 x 3 (7000 x 600 px, 819 kg, 16.8 kW).

| Absen KLCOB 0.78 | 0.78 mm | 29 x 5 = 145 | 17.4 x 1.7 m | 22272 x 2160 | 653 kg / 1,439 lb | 12.8 kW, 62 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 35 x 3 = 105 | 17.5 x 1.5 m | 7000 x 600 | 819 kg / 1,806 lb | 16.8 kW, 81 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, Prefunction B holds about 212 theater seats, 86 banquet seats at rounds of 10, or 59 classroom seats. Back row in theater is roughly 14.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
