The CELO series is AUDAC‘s first high-end, slim ceiling speaker series, consisting of four models which can guarantee an optimal experience for every situation and application. The CELO5 is the 5” model of this series. Due to its slim grill design with a very thin border of only 1 mm and a limited grill depth which extrudes from the ceiling surface by only 3.2 mm, these speakers will become nearly invisible when mounted. To make them blend in even more, the grill can be painted in the same color as the surrounding surface or an optional black grill (GLC05/B) will provide seamless integration in dark environments.
