Designed by acoustician Norman Varney, the Metu panels use reactive/diaphragmatic absorption tuned to an average NRC of 1.00 while being finished to disappear into a room — painted to match walls or dressed up as framed photos and posters rather than looking like foam egg-crate. A/V RoomService is a small Ohio-based specialty acoustics shop that designs, fabricates, and hand-finishes each panel to order rather than mass-producing a stock SKU, and it sells direct and through a limited dealer/integrator network rather than wide retail distribution.
