C6
The C6 cabinet is a full range, two way bass-reflex enclosure fitted
with a 12" LF driver passively connected to a 2" HF compression
driver which is coupled to a 60° x 40° CD horn.
The C6 cabinet is constructed from marine plywood and has an
impact resistant paint finish. The front of the loudspeaker cabinet is
fitted with a rigid metal grill covered with a replaceable
acoustically transparent foam. The cabinet top plate has an
integral handle and four M10 threaded inserts for mounting
brackets and rigging. The L shaped metal plate at the bottom of
the cabinet also incorporates a handle, four M10 threaded inserts,
a socket to accept a loudspeaker stand and, on the rear panel, two
parallel wired Speakon-NL4 or EP-5 connectors.
The C6 frequency response covers a 70 Hz to 17 kHz band - quite
sufficient for applications that dont require deep bass. However,
for high level music reproduction, the C6 benefits from the bass
extension and added power of active subwoofer systems
E18-SUB, C4-SUB or C7-SUB.
The outstanding performance features of the C6 are its narrow
dispersion angle and its very high output capability - these features
are best used for audience coverage at distances to 20 m (65 ft)
and beyond. Within a larger system C6 loudspeakers are ideal as
high power delay systems and for high intelligibility speech
reinforcement. The precisely angled rear side panels of the cabinet
allow C6s to be simply placed side by side forming a powerful
array with accurate 60° horizontal coverage per loudspeaker. To
simplify array construction an extensive range of mounting and
rigging accessories is available - please refer to the C6/C7
brochure.
Only operate C6 loudspeakers with a d&b P1200A mainframe
fitted with C6 controller modules or a d&b E-PAC (version 2) in C6
configuration, otherwise there is a risk of damaging the
loudspeaker components.
Version C690
The C690 has wider horizontal and vertical dispersion than the C6,
the only difference being the 90° X 50° CD horn. C690 is driven by
the same controller as the C6 and is suited to near field
applications where wider coverage at high SPLs is required.
Connections
The C6 cabinet is fitted with a pair of Speakon-NL4 connectors. All
four pins of both connectors are wired in parallel. The C6 uses the
pin assignments 1+/1. Pins 2+/2 are designated to C and E-
Series active subwoofers. Using one connector as the input, the
second connector allows for direct connection to additional
loudspeakers.
The C6 can be supplied with EP-5 output connectors as an option.
Pin equivalents of Speakon-NL4 and EP-5 connectors are listed in
the table on the left.
