C8-i
General Description
The C8-i is the latest innovation in line array
technology for permanent installations. It
incorporates an advanced transducer technology
for both midrange and high frequency reproduction,
both of which join a common waveguide. At least
two amplifier channels are required, one for low
freq., one for mid/hi which is coupled via an internal
passive crossover network.
The centrally located mid/high section provides 10°
vertical coverage and variable horizontal coverage.
The horizontal pattern may be altered to optimize
coverage within the context of the application.
The horizontal coverage angle may be defined
symmetrically or asymmetrically by standard
angles between 50° and 140° in 10° increments
or may be custom configured with continuously
variable Clair TrueFit custom waveguides. The
horn and waveguides are constructed, as all Clair
waveguides are, with CNC machined Baltic birch
plywood. This is symmetrically flanked by the C8-i
low frequency sections. Each 8” low frequency
driver is front loaded in its own tuned reflex
chamber.
The C8-i speaker cabinet is designed to provide
exceptional intelligibility and is capable of a
frequency response of 60Hz–20kHz.
The C8-i has one of the most versatile, quick and
easy to use rigging systems in the industry today.
Each enclosure is equipped with structurally
integrated bimodal rigging to allow for quick
coverage angle adjustments for multiple venue
arrangements. Rear rigging hardware allows for
angle adjustments between 0 and 10 degrees (0,
1.25, 2.5, 3.75, 5.0, 6.25, 7.5 and 8.75 degrees).
As with all Clair Brothers products, the C8-i is
constructed of the finest Baltic birch plywood and
finished with a rugged exterior epoxy to withstand
the most demanding conditions.
The speaker grille is constructed of high-grade
14 gauge perforated steel and finished with a
commercial grade powder coat finish.
