Monitor Audio C180 In-Ceiling Speaker

8" two-way in-ceiling speaker with pivoting tweeter

The C180 is a compact in-ceiling speaker featuring an 8-inch MMP®II bass driver and C-CAM® tweeter for use in stereo for music, or in multiples for home theatre. As part of the 100 Series of architectural speakers, it is easy to install and offers the biggest bass driver size of any speaker in its class, providing a convincing full-range sound in a wide range of locations.

• 2-way design with pivoting C-CAM® tweeters (15 degrees of play).
• High overall efficiency.
• High frequency level adjustment (3dB).
• Audio match with BR-CP, Radius-CP, Climate 10 and Bronze BR and Radius Series hi-fi speakers.
• Our innovative Tri-Grip fixing system is easier to install than conventional clamping schemes but provides three times the surface area and a better surface seal, maximizing bass response and mid-range clarity.
• Aluminum alloy grille for rust-free performance and longevity. It is non magnetic and lighter in weight.
• Paint-able surface to blend with the living environment. A paint mask and additional scrim material are provided for trouble free painting.
• Fire retardant to UL-94 VO rating.
• Splash and humidity proof for installation in shower room or pool areas.
• Features dust protection cover that is designed to prevent the ingress of dirt or dust into the driver and crossover.

Technology

Gold Dome C-Cam: The gold dome tweeter is formed from a ceramic-coated aluminium/magnesium alloy, gold anodised to a specific thickness for ideal stiffness and damping characteristics. Its new profile and surround geometry have been developed using advanced modelling tools, to provide the optimum qualities for accurate sound reproduction. The new design moves the first order of breakup to beyond 35kHz, producing a linear response way beyond audibility, which matches the wide frequency bandwidth available from HD music and cinema sound formats.

The gold dome is thinner, lighter, more rigid and therefore more efficient than domes made from other materials which are prone to distortion in the audio band.

MMP II: Metal Matrix Polymer driver cones have a polypropylene base loaded with metallic particles to offer a rigid and responsive structure. They are manufactured using a sophisticated high-pressure injection process, which modulates cone thickness at critical points to optimise stiffness and consistency, resulting in a superior sonic performance.
