Under a 8.8 m ceiling with 1.5 m trim and 0.3 m clearance you get 14 rows of 500 mm tile flown. Along the 21 m wall a Absen PL2.5 Plus V2 wall runs 33 x 14 (6600 x 2800 px, 3,604 kg, 73.9 kW).
| Panel | Pitch | Wall (cols x rows) | Size | Resolution | Weight | Power (max) |
|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 28 x 20 = 560 | 16.8 x 6.8 m | 21504 x 8640 | 2,520 kg / 5,556 lb | 49.6 kW, 238 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 33 x 14 = 462 | 16.5 x 7 m | 6600 x 2800 | 3,604 kg / 7,944 lb | 73.9 kW, 355 A @ 208 V |
| Absen PL3.9 Plus V2 | 3.9 mm | 33 x 14 = 462 | 16.5 x 7 m | 4224 x 1792 | 3,604 kg / 7,944 lb | 64.7 kW, 311 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, Grand Horizon F holds about 550 theater seats, 225 banquet seats at rounds of 10, or 154 classroom seats. Back row in theater is roughly 14 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
