E15X-SUB

The E15X-SUB is a compact high performance subwoofer for use with

d&b E-Series loudspeakers. It employs a long excursion 15" neodymium

driver in a bass-reflex enclosure.

Due to the built-in passive crossover network the E15X-SUB can be

operated in parallel to E12 or E12-D loudspeakers on one amplifier

channel, greatly extending the low frequency headroom and bandwidth

of the systems.

As an alternative it can be operated actively driven by its own amplifier

channel without the need for any changes to the cabinet. In active mode

the E15X-SUB can be used to supplement any of the E-Series cabinets,

its frequency response extending from 37 Hz to 100/140 Hz.

The E15X-SUB cabinet is constructed from marine plywood with an

impact and weather resistant black paint finish. The front of the

loudspeaker cabinet is protected by a rigid metal grill in front of an

acoustically transparent foam. The cabinet incorporates a pair of

handles and an M20 threaded flange in the top panel that accepts the

d&b Z5013 Loudspeaker stand for the deployment of full range

cabinets.

Four rubber feet prevent cabinet movement and protect the bottom

panel against scratching. Correspondingly shaped recesses in the top

panel of each cabinet prevent cabinet movement when stacking E15X-

SUBs.

NOTICE:

Only operate E15X-SUB loudspeakers with a correctly configured d&b

amplifier, otherwise there is a risk of damaging the loudspeaker

components.

E15X-SUB cabinet options

The special color (SC) version of the cabinet is available in all colors of

the RAL color table. The connector type is NL4.

The weather resistant (WR) version is available in black only. It is

equipped with a fixed input cable (5 m / 16.4 ft, type H-07-RN-F

2 x 2.5 mm

Connections

The E15X cabinet is fitted with a pair of EP5 connectors. All five pins of

both connectors are wired in parallel. The E15X-SUB uses the pin

assignments 3/4 and 5. Pin 5 is used for SenseDrive (only available

when using a D12 amplifier and 5-wire cabling). Pins 1/2 are

designated to E-Series full range systems. Using the male connector as

the input, the female connector allows for direct connection to additional

loudspeakers.

The E15X-SUB can be supplied with NL4 connectors as an option. The

D12 SenseDrive function is not available when using NL4 connectors.

Pin equivalents of EP5 and NL4 connectors and the fixed cable option

are listed in the table below.
