Coliseum at Alliant Energy Center

Plan view

Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.

LED wall that fits

Under a 29.3 m ceiling with 1.5 m trim and 0.3 m clearance you get 54 rows of 500 mm tile flown. Along the 78.8 m wall a Absen PL2.5 Plus V2 wall runs 126 x 54 (25200 x 10800 px, 53,071 kg, 1088.6 kW).

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, Coliseum holds about 13,611 theater seats, 5,568 banquet seats at rounds of 10, or 3,828 classroom seats. Back row in theater is roughly 71.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
