DESCRIPTION:
The QUAD Industrial CONCOURSE C4 is a two way round ceiling speaker with a
4” LF, 1” soft dome tweeter and passive crossover. The Concourse C4 is intended
for small room applications requiring high quality speech reinforcement and/or
background music.
The CONCOURSE C4 has switch settings for 4 and 16 ohm low impedance,
allowing efficient use of amplifier power and parallel looping connections with no
transformer losses or signal degradation.
For distributed applications, the CONCOURSE C4 has an integral transformer
rated at 30-15-7.5-3.75 watt taps @ 70volts and 30-15-7.5 watt taps @100volts.
The CONCOURSE C4 includes a back box and ‘C’ ring for weight distribution on
ceiling finishes. In addition, the C4 has an optional mud ring and ceiling tile
mounting (with integral terminal box containing conduit knockouts).
All components (including grill) are attached to a steel tether, which in
turn is attached to an external anchor point.
