CAMBRIDGE AUDIO C155 In-Ceiling Speakers (Pair)

The Cambridge Incognito C155 offers superior sound quality from an unobtrusive ceiling speaker.

The C155 (also known as the SS10) speakers have been designed to match the sound quality of decent bookshelf speakers and to take into account angles, frequencies and energy distribution characteristics of in-ceiling applications.

As with other Incognito speakers, the C155s are finished in an unobtrusive matt white that can also be painted to match personal decor that will blend into any room, giving you quality but discreet audio.

Full range compact ceiling speakers. Low distortion and a smooth, natural frequency response make the Control 24C Micro ideal for medium volume business music systems as well as for the medium to low SPL segments of larger or louder systems.
