The BC-104 R enclosure speaker from the RCS series offers a compact, acoustically optimized solution for professional PA installations. Combining elegant design with robust construction, it delivers excellent speech intelligibility and balanced music performance—perfect for use in public buildings, hallways, lobbies, or educational institutions.

Constructed from impact- and scratch-resistant plastic, the housing ensures minimal resonance and vibration. Its subtle softline design and sound-optimized perforated grille blend seamlessly into any environment and are particularly favored by architects.

A key feature of the BC-104 R is the built-in volume control on the low-impedance side. Located at the bottom (or side when mounted horizontally), it can be adjusted using either a screwdriver or the included control knob—enabling convenient level adjustment directly at the speaker.

Installation is quick and secure: the front grille can be removed with a screwdriver to access the mounting points. The speaker supports theft-resistant mounting in horizontal, vertical, or ceiling positions. The enclosure also provides space for optional add-ons like relay modules.
