The CSS230 is a brilliantly innovative back-box design with an impressively shallow 50 mm (2") mounting depth, custom built to offer hi-fi levels of performance in spaces where no high-quality speaker has gone before. Key Features: Super-slim mounting Hybrid CP enclosed or open back-box option 3 x 3" C-CAM cone bass-mid drivers 1 x 3/4" C-CAM Gold Dome tweeter Gold plated sprung push terminals Tri-Grip II for easy and secure fitment Compatible with CB6 pre-construction bracket British High-Fidelity Architectural Sound Redefined Between 2" stud frames or where pipework or cabling reduces mounting depth, the hybrid back-box construction and proprietary full-range driver array combine to deliver consistent audio quality with exceptional installation versatility. The hybrid backbox provides the best of all worlds for installers and customers. Combined, the three proprietary 3" mid-bass units achieve the bass output of a 6 1/2" driver, all from a super-stealthy flush-fitted profile. In keeping with Monitor Audio’s renowned design rigour, the crossover comprises high-quality film capacitors and low-loss inductors—selected for signal integrity—ensuring peerless audio detail and dynamics from a speaker of its size and application. When the CSS230 is in ‘ported’ mode, a fine gauze protects the acoustic system from dust ingress. Optional square or premium grilles can be used with this model.
