Monitor Audio Core C165 6.5-inch In-ceiling Speakers

All ‘Trimless’ 100 Series loudspeakers combine the proprietary technologies and materials found in our award-winning Bronze and Radius in-room loudspeakers with ‘stealthy’ trimless grilles for easy, discreet, décor-friendly installation. The ‘Trimless’ 100 Series models are two-way designs that utilise advanced MMP®II bass drivers and Monitor Audio’s trademark C-CAM® gold dome tweeter to provide high-performance sound, ease of drive, and wide frequency response and dispersion. Optimum imaging and set-up are established via a pivoting tweeter and high-frequency (+3dB / 0dB /-3dB) level adjustment.

We invest as much care, expertise and research in the smallest loudspeaker as we do in the grandest. Irrespective of architecture or interior design, Monitor Audio’s range gives you the freedom to supply high quality sound from a versatile mix of floor, stand, wall and flush-mounted speakers. The C165 is a brilliant little in-ceiling speaker which is easy to install and has a clear, dynamic performance worthy of the brand. As part of the 100 Series of architectural speakers, it offers the biggest bass driver size of any speaker in its class, providing a convincing full-range sound in a wide range of locations.
