What fits in Cowdray Hall & Council Room

With a 5 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 52 tiles wide by 6 high (312 tiles, 26 x 3 m, 8736 x 1008 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 3,120 kg and draws up to 57.7 kW (278 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 473 theater, 193 banquet, or 133 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

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.

Planning notes

No rigging point data is published for this venue yet; plan on ground-supported LED or ask the venue for its rigging plot. 6 of the 14 rooms sit under 3.5 m, which rules out flown LED there and limits ground-stacked walls to about 6 rows of 500 mm tile. Cowdray Hall & Council Room is a long room (3.7:1), so put the wall on the short end and expect the back row to be 33 m out; a 2.97 mm pitch holds up at that distance.

Data source
