Safety precautions
Information regarding use of loudspeakers
WARNING! Never stand in the immediate vicinity of loudspeakers driven at a high
level. Professional loudspeaker systems are capable of causing a
sound pressure level detrimental to human health. Seemingly non-
critical sound levels (from approx. 95 dB SPL) can cause hearing
damage if people are exposed to it over a long period.
In order to prevent accidents when deploying loudspeakers on the
ground or when flown, please take note of the following:
When setting up the loudspeakers or loudspeaker stands, make sure
they are standing on a firm surface. If you place several systems on
top of one another, use straps to secure them against movement.
Only use accessories which have been tested and approved by d&b
for assembly and mobile deployment. Pay attention to the correct
application and maximum load capacity of the accessories as detailed
in our specific “Mounting instructions” or in our "Flying system and
Rigging manuals".
Ensure that all additional hardware, fixings and fasteners used for
installation or mobile deployment are of an appropriate size and load
safety factor. Pay attention to the manufacturers' instructions and to
the relevant safety guidelines.
Regularly check the loudspeaker housings and accessories for visible
signs of wear and tear, and replace them when necessary.
Regularly check all load bearing bolts in the mounting devices.
CAUTION! Loudspeakers produce a static magnetic field even if they are not
connected or are not in use. Therefore make sure when erecting and
transporting loudspeakers that they are nowhere near equipment and
objects which may be impaired or damaged by an external magnetic
field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic
data carriers (floppy disks, audio and video tapes, bank cards, etc.) is
sufficient; a distance of more than 1 m (3 ft) may be necessary with
computer and video monitors.

E15X-SUB
Fig. 1: E15X-SUB loudspeaker
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 mm2/AWG 13).
Connections
Fig. 2: Connector wiring
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.

Operation with D6 or D12
Passive operation connected in parallel to E12 or E12-D
Select the E12-X or the E12-DX setup when E12 or E12-D cabinets are
used in combination with E15X-SUB loudspeakers on the same channel.
Compared to the standard E12, E12-D setups the X versions provide a
dedicated correction for the combined frequency response of these
systems. D12 amplifiers have to be set to “Dual Channel” to access
these.
IMPORTANT! Selecting the E12-X (E12-DX) setup enables a combination of one E12
(E12-D) and one E15X-SUB to be driven by the respective D12 or D6
channel.
In applications with low continuous levels and low ambient
temperatures up to three cabinets can be connected to a D12 channel.
Active operation
Select the E15-SUB setup to drive E15X-SUB in active mode. E-Series
full range cabinets should now be operated in CUT mode to increase
the system headroom. Within the D12 amplifier the E15-SUB setup is
available in “Dual Channel” and “Mix TOP/SUB” mode.
IMPORTANT! Selecting the E15-SUB setup enables up to two E15X-SUB loudspeakers
to be driven by the respective channel.
In applications with low continuous levels and low ambient temperatures
up to three cabinets can be connected to a D12 channel.
To apply SenseDrive for the subwoofer, EP5 connectors and 5-wire
cables have to be used. When operated in Mix TOP/SUB" mode, the
subwoofer has to be fed from the output B connector of the D12
amplifier.
Controller settings
100 Hz circuit
If the 100 Hz circuit is selected the upper operating frequency of the
system is reduced from 140 Hz to 100 Hz. It can be used when actively
driven E15X-SUB subwoofers are used to supplement E-Series cabinets
operated in full range mode, for example in a distributed sound system.
The 100 Hz mode can also be used to compensate for the effect of
close coupling between the E15X-SUB and E-Series cabinets operated
in CUT mode, for example in a drum fill setup.
Operation with E-PAC
Selecting E15-SUB mode enables the E-PAC to drive one E15X-SUB
loudspeaker.
The 100 Hz setting is available. The characteristics of the 100 Hz setting
are explained in the previous section "Operation with D6 or D12 -
Controller settings".
