In-Ceiling LCR Speaker. 6.5" Angled Graphite Bass. 1" Pivoting Aluminium Tweeter
The C660 is a discreet in-ceiling speaker capable of providing both wide dynamic range and excellent stereo imaging in stereo or surround applications.

At the heart of the design is a high-power 6.5" Injection Moulded Graphite bass driver angled at 15∞, combined with an independently mounted 1" pivoting aluminium dome tweeter. This combination provides both excellent dynamic range and accurately focussed sound.

With a power handling of 125W per channel, capable of high sound pressure levels without compression or distortion.

In its own right this speaker is an exceptional speaker, but when combined with an active subwoofer such as the S66, it forms a powerful yet discreet home theatre system capable of the highest standards of performance.
