i218-M
General Description
The i218-M is Clair Brothers mobile large
format innovation in line array technology.
Built for large environments where maximum
output (145dB max) and coverage are
required. It incorporates an all new approach
in modular midrange and high frequency
technology, providing excellent controlled
directivity. The centrally located mid/high
modules provide 90° horizontal by 10° vertical
coverage and are symmetrically flanked by
the i218-M low frequency sections. Each
18 in. low frequency driver is front loaded in
independent tuned vented chambers.
i218-M enclosures are equipped with
structurally integrated bimodal rigging that
allow the line array’s vertical coverage to be
customized to meet the specific needs of an
application. Rear rigging hardware allows for
angle adjustments between 0° and 10°. The
i218-M standard input connector is the EP-8.
As with all Clair Brothers speaker products,
the i218-M is constructed with the finest
Baltic birch plywood and finished with a
rugged exterior black epoxy mastic finish
to withstand the most demanding mobile
conditions.
