3D room model — PA + screens

Built from the HouseRight AVL set 210606 (draft CDs 3/25/26): plan AVL 020, ceiling dims AVL 402, sections AVL 105 / 405, elevation AVL 106. Plan geometry scaled from the vector drawings (±6"). Underside of structure 27'-8" at the upstage wall rising to 30'-0" at the rear (AVL 105 section). Flown sub count (2 per side) inferred from the 300 lb sub pick. The SPL map is a simplified broadband estimate for comparing deployments; the Soundvision file is the reference.
