The Clair Brothers CS18-II is a newly designed
sub-low frequency loudspeaker. The CS18-II
provides maximum sub bass reinforcement
proportional to its size which is ideal for a
variety of fixed installations where spacesaving is a consideration.
Its compact size makes it a perfect companion
for a variety of Clair Brothers full range
installation loudspeakers such as CAT214, R2,
R3, R4 and FF2 series.
The CS18-II is designed with a single high
output transducer that delivers a usable inroom frequency response down to 32 Hz.
The specially coated 18 in. cone provides
exceptional linear excursion. The result is
a high power handling, high performance
subwoofer that provides tightly controlled lowfrequency extension.

As with all Clair Brothers products, the CS18-II
is constructed of the finest Baltic birch plywood
with a rugged epoxy finish to withstand the
most demanding conditions.
The speaker grille is constructed of a durable
14 gauge steel which is powder coated and
backed with a high grade reticulated foam.
