The Monitor Audio Super Slim CSS230 is an innovative ceiling speaker designed for installations where space is restricted but high-quality sound is required. With a mounting depth of just 50mm, this compact yet high-performance speaker delivers Monitor Audio's signature hi-fi sound in spaces where traditional speakers cannot fit. Its hybrid back-box design, advanced driver configuration, and premium build make it an ideal choice for both home and commercial applications.
The CSS230 features a smart hybrid design, allowing it to be used with either a sealed "Controlled Performance" back-box for improved sound isolation or as an open-back system for extended bass response. It utilises three 3" C-CAM bass/mid drivers, which are arranged radially around a 19mm C-CAM Gold Dome tweeter. This configuration ensures wide dispersion and excellent clarity. A magnetically attached trim-less grille, available in round or square options, provides an unobtrusive appearance that can be painted to match décor. Built with ABS housing and a painted steel grille, it is durable, reliable, and UL94 rated.
