Key Information

  • Sensitivity (1W @ 1M):86 dB

  • Mounting Depth:50 mm
  • Power Handling (RMS):40 Ws

  • Driver Size:3 "

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.

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.

Optional square or premium grille can be used with this model.

Rotating bottle warmer
Barely warms up faster then other baby bottle warmer. The timing for the 9 oz Philips Avent natural baby bottle with 160 mL only got milk to 92 F so if wanting to get to higher temp you have to let it heat for a little longer. Without a lid the water does evaporate pretty quickly requiring frequent refills. The design also makes it hard to wash. Build quality is excellent but with the larger footprint it takes up more counter space than other bottle warmers.
