In-Ceiling Speaker. 6.5" Kevlar Bass. 1" Pivoting Aluminium Tweeter
Proficient Audio compact C645 in-ceiling speaker is anything but compact when it comes to performance.

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

With a power handling of 150W per channel and 92dB sensitivity, the C645 can 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.

In critical applications such as those for living rooms and master bedrooms, the C645 is the ideal high-performance compact stereo speaker.
