Monitor Audio CS140 Front

The CS140 is a compact In-Ceiling speaker with a mounting depth of just 4", making it 25% smaller than similar products. It can be mounted in a wall as well as a ceiling, making it a very adaptable choice. To add to the versatility, all CS models are splash and humidity proof, making them an ideal choice for bathrooms and kitchens. Featuring the unique Tri-Grip clamping system, you'll find these speakers extremely easy to install. The magnetically attached grille is completely paintable, so blending in with existing decor is no problem at all for the CS140. You also have the option of a round or square grille, so please remember to specify which you'd prefer when you order!
