The in-ceiling speaker RC-130 C from RCS Audio-Systems is a ceiling in-ceiling speaker designed for use in sound systems, particularly in public spaces where discreet yet reliable sound reproduction is required. The device combines a modern design with tool-free installation thanks to the quick-tension fastening system, enabling fast and secure installation. After removing the perforated plate, only four screws need to be tightened to secure the speaker. The mounting frame is made of robust plastic, and the cover plate is made of coated steel, ensuring a theft-secure construction. The frame height is approximately 2 mm, contributing to a subtle visual appearance.

Applications include public buildings, administrative buildings, schools, shopping centres, and other spaces where unobtrusive yet powerful sound coverage is necessary. The construction is designed for use in dry indoor environments; an optional humid environment version (FI-100) is available, designed for more demanding environments with increased humidity.

Functions and equipment in detail are based on a 2-way coaxial chassis with a diameter of 165 mm (6 1/2 inch). The woofer membrane is designed for wide bandwidth to ensure even reproduction in the lower frequency range. An integrated tweeter ensures detailed reproduction of speech and music. The built-in transformer enables adaptation to 100-V networks and ensures stable sound performance, meeting even professional requirements. The rated power is 30 W, the program power is 40 W.

Technology explained simply shows that the speaker is designed for operation with 100-V amplifiers. Adaptation is achieved via the built-in transformer, which allows different power levels (30 W, 15 W, 7.5 W). The frequency range is between 35 Hz and 20,000 Hz (±10 dB), enabling comprehensive sound reproduction from deep bass to high frequencies. The sound pressure level is 92 dB at 1 W/1 m, and the maximum sound pressure reaches 108 dB at 6 kHz. The radiation angles are 180° at 1 kHz, 80° at 4 kHz, and 110° at 8 kHz, ensuring broad yet targeted sound dispersion.

Compatibility and accessories refer to use in 100-V networks, which are standard in many professional sound systems. The optionally available humid environment version FI-100 is designed for environments with increased humidity, although the exact technical details of the humid environment version are not specified in the current text. Installation is carried out in ceilings with a cutout size of Ø 226 mm, and the installation depth is 70 mm.

Installation and mounting is performed using the quick-tension system, enabling tool-free fastening. The installation requires no special tools, only a screwdriver-like device to tighten the four screws. The construction is designed to fit easily into standard ceiling openings.

Operational advantages lie in the combination of discreet design, high sound quality, and easy installation. The theft-secure construction reduces the risk of theft in public areas. The use of a 2-way coaxial chassis ensures clear, spatially balanced sound reproduction, suitable for both speech transmission and music. Adaptation to 100-V networks enables flexible integration into existing sound systems.
