MF 33EN
Two-Way Passive Ceiling Speaker
MF 33EN is a two-way ceiling speaker designed for recess installation into ceilings or panels. It is especially suitable for broadcasting background music into commercial spaces, but also alarm messages thanks to the highly intelligible voice reproduction and the EN 54-24 certification. It features a UL rated plastic cabinet with a steel magnetic grille and is extremely easy to install. The terminal connection blocks, for input and output flameproof cables, are made of ceramic material. A thermal fuse protects the integrity of the line in case of heat affecting the speaker.

Multipurpose sound
A combination of modern design, a wide coverage angle of 100°x160° and RCF signature sound quality to deliver a supreme audio experience in any application. Their 2-way / 3-transducers full-range reflex-loaded speaker design does not require complementary SUBs. There is enough power for a uniform and rich sound distribution for a wide range of installations. The target application range is extremely wide and varies from retail stores to bars and restaurants, meeting rooms, education or public facilities, and in general to any A/V application and Voice Alarm installation.
Improve the audio atmosphere
Music nurtures engagement and improves the feeling of hospitality provided by the environment. All products designed for Business Music applications offer optimal background performance preserving the same quality even during high-powered foreground music. Their extra-wide directivity allows you to significantly reduce the number of speakers and installation points.
Voice alarm ready
The EN 54-24 certification and the highly intelligible voice reproduction make it perfect for voice alarm and EVAC messages (sensitivity 91 dB 1W @ 1m in the range 400 Hz ÷ 8000 Hz according to EN 54-24). The same speaker can be used for both music distribution and Voice Alarm applications.
Hidden power
The discreet and subtle design blends perfectly into any architecture, without compromising on sound performance and ease of installation. No visible screw, no logo, or graphic details. The grill is magnetically removable, ensuring practical and easy maintenance. MF 33EN disappears from view once recessed in a linear lighting canal. It also becomes virtually invisible when flush-mounted into the ceiling or furnishings, after painting its grille.
New shape of sound
MF speakers can be driven by both low impedance or constant voltage amplifiers, with mode and power selection, both accessible by simply removing the grille. Their extra-wide directivity significantly reduces the number of speakers and installation points.
