Biamp SPA-GRB100
Desono black ceiling loudspeaker grilles (6-pack)
The Biamp SPA-GRB100 is a six-pack of black replacement grilles for Desono ceiling loudspeakers, offering a discreet alternative to the standard white finish. Made of powder-coated perforated steel backed with acoustically transparent, color-matched cloth, the grilles blend into dark ceilings while preserving sound quality.
Sized to fit Desono CM20DTS and CM30DTD ceiling loudspeakers with a grille diameter of approximately 221 mm (8.69 in), each unit maintains the loudspeaker's coverage and clean, low-profile appearance. The multi-pack makes it easy to standardize a black aesthetic across theaters, retail, hospitality, and design-forward interiors.
