The ceiling and wall-mounted speaker RC-110C from RCS Audio-Systems is a 2-way coaxial speaker designed for use in 100-V amplifier systems. It is suitable for installation in ceilings or walls and is commonly used in office buildings, schools, shopping centres or other public spaces where discreet and uniform sound coverage is required. The device features a coaxial chassis with a wideband woofer and an integrated tweeter, enabling clear and balanced sound reproduction over a wide frequency range.

Applications

The speaker is intended for use in dry indoor environments. A special humid environment version is also available, making it suitable for rooms with increased humidity, such as bathrooms or kitchens. Installation is carried out by tightening four screws, with a quick-tension fastener simplifying the process. The frame height is 2 mm, ensuring an almost flush installation appearance. The construction is theft-secure, allowing the device to be used in public areas with increased theft risk.

Functions and equipment in detail

The speaker chassis has a diameter of 165 mm and is white. The grille is made of coated steel and is removable, facilitating maintenance and cleaning. The mounting frame and retaining parts are made of high-quality plastic, ensuring stable installation. The maximum installation depth is 70 mm, and the mounting hole cutout has a diameter of 200 mm ± 5 mm. The external dimensions of the speaker are Ø 226 mm.

Technology explained simply

The speaker is designed for 100-V systems, meaning it connects to a central amplifier system operating at high voltage to compensate for line resistance over longer distances. The rated power handling is 10 W (music), with a peak power of 40 W possible. Adjustment is done via a 100-V connection socket, configurable for power ratings of 10, 50, or 2.5 W. The nominal impedance is 8 Ohm, which is standard for use in conventional amplifier systems. The frequency range extends from 50 Hz to 20,000 Hz, enabling reproduction of deep bass to high treble frequencies. The sound pressure level is 91 dB at 1 W power and a distance of 1 metre, providing sufficient loudness for indoor spaces.

Compatibility and accessories

The speaker is compatible with 100-V amplifier systems. As an accessory, an installation socket with pin contacts (type EPIC POWER M12 G4 M16 3+PE M 0.2m) is offered for electrical connection during installation.

Installation and mounting

Mounting is done by tightening four screws, with the quick-tension fastener speeding up the installation. Installation requires a hole diameter of 200 mm ± 5 mm in the ceiling or wall. The maximum installation depth is 70 mm, so sufficient space must be available within the building component. The removable grille facilitates installation and future maintenance.

Advantages in operation

The speaker provides clear, balanced sound reproduction thanks to the 2-way coaxial chassis. The theft-secure construction and flat installation appearance with only 2 mm frame height ensure discreet integration into architecture. Use in 100-V systems enables a flexible and scalable sound distribution solution that can be adapted to specific requirements. The humid environment version extends the application range to rooms with increased humidity.
