Hall 3B at Hiroshima Convention Hall & Hybrid Studio

Hall 3B is 14.7 x 14.7 m (48 x 48 ft), 216 m² (2,326 sq ft), with a 3.5 m (11 ft) ceiling.

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 3.5 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 14.7 m wall a Absen PL2.5 Plus V2 wall runs 23 x 3 (4600 x 600 px, 538 kg, 11 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, Hall 3B holds about 293 theater seats, 120 banquet seats at rounds of 10, or 82 classroom seats. Back row in theater is roughly 7.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
