The ceiling-mounted speaker CSL-106B from RCS Audio-Systems is an in-ceiling speaker with a spot design, visually inspired by halogen lighting systems. It is suitable for installation in ceilings and walls and designed for integration into 100-volt amplifier systems. The speaker features a wideband chassis with a diameter of 64 mm and is rated for a nominal power handling of 6 watts (music), with short-term capability up to 10 watts. The impedance is 8 ohms, making it suitable for low-impedance operation as well. The frequency response ranges from 120 Hz to 20,000 Hz, ensuring a balanced sound range from low to high tones. The sound pressure level is 86 dB at 1 watt and 1 meter distance, providing sufficient loudness for indoor spaces.

Applications

The CSL-106B is designed for use in offices, waiting areas, shopping centers, hotels, or other indoor environments where discreet yet effective sound distribution is required. The spot design allows for seamless integration into architecture, as the speaker visually resembles a ceiling light fixture. Installation is performed via a cutout with a diameter of 90 mm ± 3 mm, with an installation depth of 72 mm. The external dimensions of the device are 105 mm in diameter. Mounting is achieved using two metal springs, enabling simple and universal attachment to ceilings and walls of varying thicknesses.

Functions and Equipment in Detail

The speaker includes an integrated 100-volt transformer, adjustable in three power stages (6 W, 4 W, 2 W). This allows flexible integration into existing 100-volt amplifier systems, where total power is distributed across multiple speakers. Adjustment is made via a switch on the device, enabling power to be set according to requirements and room size. Additionally, the speaker is suitable for direct operation with 8 ohm impedance and 6 watts power, making it usable with smaller, low-impedance amplifiers as well. The housing and grille are made of metal, ensuring a robust and durable construction. The device is black in color, with optional special paint finishes and a humid environment version available.

Technology Explained Simply

The technology of the CSL-106B is based on a wideband speaker that reproduces all frequencies from 120 Hz to 20,000 Hz. This includes both low bass and high treble ranges, making the speaker suitable for music and voice reproduction. The 100-volt transformer enables use in large sound distribution systems, where multiple speakers are connected via a unified network to a central amplifier. Power adjustment (6 W, 4 W, 2 W) ensures the speaker is optimally loaded according to distance from the amplifier and room size, maintaining even sound levels. The 8 ohm impedance is a standard value in the audio industry, ensuring compatibility with many amplifiers.

Compatibility and Accessories

The speaker is compatible with 100-volt amplifier systems commonly used in commercial sound distribution. Power adjustment is performed via the integrated transformer, eliminating the need for additional components. Optional special paint finishes and a humid environment version are available, enabling use in rooms with increased humidity, such as bathrooms or kitchens. Installation requires no additional tools, as the metal springs allow for easy mounting on ceilings and walls.

Installation and Mounting

Installation of the CSL-106B requires a cutout of 90 mm diameter ± 3 mm. The installation depth is 72 mm, allowing seamless integration into standard ceilings and walls. Mounting is done using two metal springs, which securely fix the device. Wiring is done via the 100-volt network, with power adjustment performed on the device itself. Connection to the amplifier is made through the existing cabling, eliminating the need for additional cables.

Operational Advantages

The CSL-106B offers discreet architectural integration through its spot design, visually reminiscent of halogen lights. Easy mounting with metal springs enables quick and secure installation. Flexible power adjustment (6 W, 4 W, 2 W) ensures optimal adaptation to various room sizes and requirements. Use in 100-volt systems enables centralized control and distribution of sound, simplifying maintenance and scalability. The robust metal construction ensures long service life and high reliability in continuous operation.
