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.

Feels good on the skin not greasy
Size: 1.3 Fl Oz (Pack of 1)
Very nice product very concentrated has a very light fragrance that dissipates very quickly not greasy. No I do not have any redness or sensitivity I wanted to try this product anyway because I'm always looking for moderately priced good quality that travels well. And this fit the bill especially with it being on sale.

Good product , but
Size: 1.3 Fl Oz (Pack of 1), Size: 1.3 Fl Oz (Pack of 1)
It seems to be a good product and it’s not too heavy , but still caused few breakouts here and there . Also, Avenue always has protective foil on their cream , this one didn’t have (I replaced it but new one also didn’t have it). Also, it goes away really fast because it’s only 1.3 ounces.
