Key Information

  • Sensitivity (1W @ 1M):86 dB
  • Cut-Out Diameter:211 mm
  • Mounting Depth:50 mm
  • Power Handling (RMS):40 Ws
  • Nominal Impedance:8 ohms
  • 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.

Too hard
Flavor Name: Chocolate Caramel, Size: 5 Ounces
The taste of the chocolate caramels was good but they werent as soft as I'd hoped. I will buy another bag to see if it was a fluke that they were harder than I'd hoped.

Rich mans candy
Flavor Name: Chocolate Caramel, Size: 5 Ounces
Very tasty, over priced. It is not caramel center, not sure what it is but it’s a change from other zero sugar candy. Wish there was more in the bag, buying one more time then that’s it. I wish I didn’t have to stop but out of my price range.
