Fig. 1: Ci80 loudspeaker
Ci80 Manual
Ci80
The Ci80 loudspeaker is a full range, two-way bass-reflex enclosure,
utilizing an 8"/1" coaxial driver combination with a passive crossover.
Coaxially mounting the 1" HF compression driver and 8" LF driver
creates a very compact single driver whilst retaining the benefits of
separate magnetic assemblies. The drivers are positioned together to
utilize the combined shape and geometry of the LF cone and HF horn to
create a single waveguide with a controlled, symmetrical, 85° conical
dispersion.
The Ci80 cabinet is constructed from marine plywood and has an
impact resistant paint finish. The front of the cabinet is protected by a
rigid metal grill fitted with an acoustically transparent foam. The 30°
angled rear side panels of the cabinet allow Ci80s to be positioned side
by side forming miniature arrays. Four M8 threaded inserts are
provided for attaching installation hardware.
NOTICE:
Only operate Ci80 loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.
Weather resistant (WR) option
NOTICE:
The WR option enables operation of loudspeakers in changing ambient
conditions, however it is not intended to enable permanent, unprotected
operation of loudspeakers outdoors.
- Provide an additional cover over the loudspeakers.
- Aim the cabinets either horizontally or with a downward tilt.
