In-Ceiling Speaker. 6.5" Graphite Bass. 1" Pivoting Aluminium Tweeter
An excellent performer in numerous applications, the C640 is a compact in-ceiling speaker capable of providing both wide dynamic range and excellent stereo imaging.

At the heart of the design is a high-power 6.5" Injection Moulded Graphite bass driver combined with an independently mounted 1°± pivoting aluminium dome tweeter. This combination provides wide dynamic range and stereo separation.

The 92dB sensitivity and 125W power handling allows this speaker to reproduce high sound pressure levels without compression or distortion.

In-room response tailoring is provided by bass and treble contour switches, which provide a cut or boost of 3dB.
An excellent compact speaker, ideal for both main and secondary rooms such as the dining room, master bedroom and study.
