iS118-M
General Description
The iS118-M is the mobile low frequency
subwoofer extension of the Clair Brothers
i-Series line array system designed for mobile
applications. This arrayable subwoofer is
specifically designed to complement the i208-M
and i212-M mobile line array systems.
The 18 in. direct radiating transducer has a
weather-resilient cone that produces exceptional
linear excursion, and maximum peak to peak
excursion of 70 mm (2.75 in). The result is a high
power handling, high performance subwoofer
that delivers tightly controlled low-frequency
response
The iS118-M has a three-point integral bimodal
rigging system for various configurations.
The cabinet may be flown above the i208-M
line array, providing an aesthetically pleasing
alternative to ground stacked subs beneath the
array. The iS118-M may also be flown along
side the i212-M array as a bass array For applications where flown rigging is not
possible, the iS118-M can serve as a ground
stacking base for the i208-M line array speakers.
As with all Clair Brothers speaker products, the
iS118-M is constructed with the finest Baltic
birch plywood and finished with a rugged exterior
black epoxy mastic finish to withstand the most
demanding conditions.
