CS118-i

General Description

The CS118-i is the mobile low frequency
subwoofer extension of the Clair Brothers C
Series line array systems designed for install
applications. This arrayable subwoofer is
specifically designed to complement the C8-i and
C12-i installation line array systems.
The 18in. direct radiating transducer has a weatherresilient cone that produces exceptional linear
excursion, and maximum peak to peak excursion
of 70mm (2.75 in). The result is a high power
handling, high performance subwoofer that delivers
tightly controlled low-frequency response.
The CS118-i has a three-point integral bimodel
rigging system for various configurations. The
cabinet may be flown above the C8-i line array,
providing an aesthetically pleasing alternative
to ground stacked subs beneath the array. The
CS118-i may also be flown alongside the C12-i
array as a bass array.

For applications where flown rigging is not possible,
the CS118-i can serve as a ground stacking base
for the C8-i line array speakers.
As with all Clair Brothers speaker products, the
CS118-i is constructed with the finest Baltic
birch plywood and finished with a rugged exterior
black epoxy mastic finish to withstand the most
demanding conditions.
