E18-SUB
The E18-SUB is a compact, very low tuned bass-reflex design
employing a single 18" driver.
The E18-SUB loudspeaker 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. Also at the front,
fittings at the top and bottom edges of the cabinet are used to
secure an optional transport lid E7908. The cabinet incorporates a
pair of steel handles and, on the rear panel, four heavy duty
wheels and two parallel wired Speakon-NL4 or EP-5 connectors.
Fitted to the top panel is an M20 threaded flange to accept the
Z5013 Loudspeaker stand for the deployment of a a full range
cabinet.
Designed to be actively driven using the d&b P1200A mainframe
or the d&b E-PAC, the E18-SUB is normally used to support d&b
full range cabinets such as the E9, C6 or E3 by covering the 38 Hz
to 110 Hz frequency band.
Only operate E18-SUB loudspeakers with a d&b P1200A
mainframe fitted with E18 controller modules or a d&b E-PAC
(version 2) in E18-SUB configuration, otherwise there is a risk of
damaging the loudspeaker components.
Connections
The E18-SUB cabinet is fitted with a pair of Speakon-NL4
connectors. All four pins of both connectors are wired in parallel.
The E18-SUB uses the pin assignments 2+/2–. Pins 1+/1– are
designated to C and E-Series full range systems. Using one
connector as the input, the second connector allows for direct
connection to additional loudspeakers.
The E18-SUB 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 below.
