The Monitor Audio CSS230 is part of the Super Slim Ceiling speaker range. At only 50mm depth,with a back box and with 3 high quality drive units, this is the perfect solution for ceiling installations with minimal space but retaining the sound of a much larger speaker. 

The CSS230 is a brilliantly innovative back-box design with an impressively shallow 50mm (2”) mounting depth, custom built to offer hi-fi levels of performance in spaces where no high quality speaker has gone before.


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 back-box provides the best of all worlds for installer and customer. 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.
