Monitor Audio CSS230 Low Profile Ceiling Speaker 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 61/2” 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. 


  • Super-slim mounting depth 50mm (2”) designed to fit within 2” stud walls or where space is restricted
  • Hybrid CP ‘Controlled Performance’ style, enclosed or open back-box option provides flexible high performance options and sound isolation in one
  • Driver configuration of three 3” C-CAM bass/mid-range drivers in a radial array around a 19mm C-CAM gold dome tweeter (fixed position) and high quality crossover design offers Monitor Audio’s award-winning signature sound quality

  • Magnetically attached ‘Trim-less’ round and square grille options for discreet, reliable and easy servicing, flexible in-wall/ceiling installation, paintable to blend with de´cor
