It is a two-way model featuring an RST II mid-bass driver and 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. As a Controlled Performance (CP) model, it is fitted with fully sealed back boxes that provide an ideal air load for the drivers, optimising mid-range and bass performance while maintaining sonic consistency regardless of interior wall construction. These rigid, mineral-filled enclosures reduce the sound from the back of the cabinet by around 30 dB. This range guarantees excellent audio quality and versatility, for a superior level of sound isolation between rooms and floors. It has a cut-out dimension of 248 mm and uses the Quik-Link speaker cable connecter, which revolutionises the ease and speed of speaker installation. Tri-Grip has also been evolved for simple, reliable, and strong fitment. Optional square grilles can be used with this model. A Choice of Grilles offering Timeless Style All Creator Series in-ceiling speakers come, as standard, with white grilles. For those that want to ‘hide’ or ‘blend’ their integrated speakers with darker décor, black grilles are also available as an optional accessory in round and square designs.
