Biamp 910-01541 CM20DT
Product Overview
The Biamp CM20DT is a 6.5-inch two-way thin-edge ceiling loudspeaker designed for interiors that call for a low-profile, paintable design grille. It combines even two-way coverage with a minimal bezel that blends into finished ceilings in retail, hospitality, and corporate spaces. The CM20DT operates in 16-ohm or 70V/100V modes, giving integrators flexibility across distributed audio system designs. It is part of the Biamp Commercial (CM) ceiling loudspeaker family.
Product Description
The Biamp CM20DT thin-edge ceiling speaker delivers background music and paging with a design-first appearance for architectural interiors. Its 6.5-inch two-way driver provides balanced full-range sound, while the thin-edge design grille keeps the loudspeaker visually discreet. A high-quality 70V/100V transformer with a color-coded tapping sticker aligns with the cables on the Quick Fit push-terminal connector, making tap selection and wiring fast during commissioning. In 16-ohm use, up to four CM20DT loudspeakers connect in parallel on each channel of a standard 4-ohm amplifier, which suits smaller low-impedance zones. The paintable grille lets integrators match the ceiling finish for a clean result. For an 8-inch thin-edge option, see the CMX20DT; for a standard-bezel 6.5-inch model, see the CM20T. Browse the Biamp collection for matching amplifiers and companion ceiling loudspeakers.
