British High-Fidelity Architectural Sound Redefined 

This small Tier 1 in-ceiling loudspeaker is designed for cost-effective installations, where product simplicity and solid acoustic performance are required. It is a two-way model featuring a C-CAM mid-bass driver and a C-CAM tweeter. The performance benefit of having both within a single design means greatly improved clarity, wider dispersion into the listening environment, and clear, lifelike, high-fidelity sound—of the quality you’d expect from any Monitor Audio passive box loudspeaker. It has a cut-out dimension of 171 mm and uses the patented Quik-Link speaker cable connector, which revolutionises the ease and speed of speaker installation. Tri-Grip has also evolved for simple, reliable, and strong fitment.
