Ci7-TOP 

Fig. 1: Ci7-TOP loudspeaker

The Ci7-TOP is the installation version of the C7-TOP loudspeaker. It is
acoustically compatible with the standard road version differing only in
cabinet construction and mounting hardware. 

The Ci7-TOP loudspeaker is a two-way hornloaded loudspeaker which
provides full range coverage at very high SPLs. The constant directivity
design of the coaxial horns used in the Ci7-TOP maintains a nominal
75°x 40° dispersion down to 600 Hz. Two passively coupled drivers are
used - a 15“ low/mid driver back loaded by a vented enclosure and a
1.5“ exit HF compression driver with a titanium diaphragm. 

The Ci7-TOP cabinet is constructed from marine plywood and has an
impact resistant paint finish. The front of the loudspeaker cabinet is
protected by a rigid metal grill, covered with an acoustically transparent
foam. Four M12 and four M16 threaded inserts are provided for
attaching installation hardware. Depending on which pair of M16
threaded inserts are used, the Ci7-TOP cabinet may be deployed for
either 75° x 40° or 40° x 75° coverage.

NOTICE:

Only operate Ci7-TOP 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.
