Monitor Audio CS140 low profile in-ceiling model features a proprietary 4-inch MMP II cone and a pivoting version of our acclaimed C-CAM Gold Dome tweeter. Engineered for excellent detail resolution and complete with either round or square grilles, the CS140 will deliver great sound with super-discreet aesthetics. Between the drivers, a simple crossover design of high-grade audiophile components ensures a smooth transition from dynamic rhythmic lows to finely detailed highs, completing a naturally clean and wide response. By specifying a Round or a Square grille option, Trimless series has been designed to complement any décor.

For the finishing touch, trimless grilles are held in place magnetically by high power neodymium magnets. The CS range offers a choice of interchangeable round or square grilles, and for the right look in any environment, all CS grilles are paintable: a paint mask and additional scrim material is provided to help make painting trouble-free.

All CS models use fire retardant materials specified to U.L rating, are splash and humidity proof, and feature dust protection covers that are designed to prevent the ingress of loose building materials or dust into the driver and crossover network.
