The BC-104 RCS enclosure loudspeaker is designed based on the latest acoustic and material engineering standards. With its modern, architecturally appreciated “softline” design and a durable, resonance-free plastic housing, it delivers both clear voice reproduction and musical fidelity in indoor environments.

The speaker features a high-performance 165 mm wideband driver with integrated high-frequency cone, supported by a high-quality 100 V transformer for use in public address systems. Power taps of 4, 2, and 1 W are available for flexible system design. With an efficiency of 96 dB SPL at 1 W/1 m and a max SPL of 103 dB, the BC-104 ensures clear audio even in noisy environments.

Installation is quick and tamper-proof: simply remove the perforated metal grille using a screwdriver to access the mounting points. The loudspeaker can be installed horizontally, vertically, or on the ceiling. The enclosure includes space and mounting options for optional components, such as a relay module.
