C7-SUB
The C7-SUB is a bass-reflex design employing a long excursion 18"
driver. The large, specially shaped reflex port enables the C7-SUB
to achieve high sound pressure levels with minimal power
compression and breathing effects.
The C7-SUB 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, and fitted with catches to the top
and bottom for securing an optional transport lid E7916. The
cabinet incoporates two steel handles, four M10 threaded inserts
for attaching installation hardware and four heavy duty wheels. An
M20 threaded flange in the top panel accepts the d&b Z5013
Loudspeaker stand for the deployment of full range cabinets.
CAUTION!
Only operate C7-SUB cabinet with a d&b D12 or E-PAC amplifier
in C7-SUB mode or a P1200A mainframe fitted with a C7-SUB
controller module, otherwise there is a risk of damaging the
loudspeaker components.

Connector wiring
The C7-SUB cabinet is fitted with a pair of EP5 connectors. All pins
of both connectors are wired in parallel.
The C7-SUB uses the pin assignments 3/4 and 5 (Pin 5: SenseDrive
- D12 only and in conjunction with 5-wire cables). Pins 1/2 are
designated to d&b full range systems.
Using one connector as the input, the second connector allows for
direct connection to additional cabinets.
The C7-SUB can be supplied with NL4 output connectors as an
option using the pin assignment 2+/2–. Pins 1+/1– are designated
to d&b full range systems.
