What fits in Great Lakes Grand Ballroom

With a 4 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 52 tiles wide by 4 high (208 tiles, 26 x 2 m, 8736 x 672 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 2,080 kg and draws up to 38.5 kW (185 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 1,443 theater, 590 banquet, or 406 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. 20 of the 45 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.

Data source

Published dimensions. Dimensions from the venue's published meeting-space specifications (source). Rooms drawn as boxes use published length x width; square rooms were derived from published area only, so treat their shape as approximate. Venue managers: send a floor plan to upgrade your listing to production-ready.
