Description

Monitor Audio C3M - Premium Three-Way In-Ceiling Speaker

The Monitor Audio C3M is a top-tier, three-way in-ceiling speaker from the Creator Series, engineered to deliver exceptional sound quality while blending seamlessly into your living space. Designed for medium-sized rooms, the C3M offers a refined balance of performance, design, and installation ease—perfect for premium music and home cinema systems where visible speakers aren’t an option.

At the heart of the C3M is a meticulously crafted driver array. A 7" RDT III bass driver delivers fast, deep and articulate low frequencies, while a 4" midrange and 1" tweeter—mounted concentrically using Monitor Audio’s IDC II module with an advanced UD Waveguide—handle mids and highs with precision and clarity. This three-way configuration ensures a wide frequency response (45Hz–35kHz), smooth off-axis performance, and excellent detail at both high and low volumes.

The C3M is as installer-friendly as it is acoustically capable. Monitor Audio’s innovative Quik-Link system allows the speaker to be wired and connected magnetically before installation, streamlining the fitting process. The secure Tri-Grip II mounting ensures a flush fit and reliable hold, even in less-than-perfect ceiling materials.

With its paintable, low-profile grille and clean, modern aesthetic, the C3M disappears visually—while delivering room-filling sound that’s anything but subtle.
