Product Details

Between 50mm 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.
