1.1 Information regarding the use of loudspeakers
Potential risk of personal injury
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.
Potential risk of material damage
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.

d&b 18S/18A-SUB Manual 1.6 en4

2.1 Product description
The 18S-SUB and 18A-SUB are compact high performance
subwoofers for use with d&b xS-Series and xA-Series
loudspeakers. The cabinets house a long excursion 18”
neodymium driver in a bass-reflex design.
The 18A-SUB incorporates the same acoustic components as the
18S-SUB, however, the cabinet is equipped with an integrated
rigging system for the design of vertical arrays. The 18A-SUB can
be combined with 10A and 10AL loudspeakers.
The frequency response extends from 37 Hz to 140/100 Hz.
The enclosures are constructed from marine plywood with an
impact resistant black paint finish. The fronts of the cabinets are
protected by a rigid metal grill backed by an acoustically
transparent foam.
The 18S-SUB is equipped with four rubber feet to prevent cabinet
movement and protect the bottom panel against scratching.
The cabinets are Ball Impact Resistant according to DIN 18032-3.
18S-SUB rigging components
The 18S-SUB side panels are each equipped with a pair of M10
threads to accept the Z5410 Horizontal bracket 18S/27S. The
threaded inserts are covered by dummy caps in cabinet color. The
caps must be removed before mounting any accessories.
18A-SUB rigging components
18A-SUB cabinets are connected to form a vertical array each
using the Z5418 Connector plates xA-SUB. Up to four 18A-SUB
cabinets can be connected. When integrated at the top of a 10A
or 10AL array, up to two 18A-SUB cabinets can be combined with
up to six 10A/10AL cabinets.
Vertical arrays are supported using the Z5414 Flying bar xA and
the Z5413 Flying bar connector plates xA. For approved
configurations as well as safety and mounting instructions, refer to
the respective rigging manual.
2.2 Connections
The cabinets are fitted with a pair of NL4 connectors and a two
pole screw terminal block (ST). All four pins of both NL4
connectors are wired in parallel. The cabinets use the pin
assignments 2+/2–. Pins 1+/1– are designated to full range
cabinets.
Pin equivalents of the applicable connector options are listed in the
table below.
NL4 1+ 1– 2+ 2–
ST n.a. n.a. + –

Fixed cable connection
The 18S-SUB and 18A-SUB loudspeakers are each supplied with
a cover plate [1] and a rubber grommet feed through [2]. For
indoor operation, these items can be used to hide the connector
panel, if required. For unprotected outdoor operation, the
connector panel must be covered, i.e. both items must be used to
achieve an IP degree of protection of IP34.
To install the fixed cable connection, proceed as follows:
Tools required: Philips screw driver (#PH2).
1. Prepare the rubber grommet and the connection cable.
2. Remove the knockout opening in the cover plate and attach
the rubber grommet correspondingly.
3. Insert the connection cable through the rubber grommet and
connect the cable wires to the screw terminal.
Þ Observe the correct polarity!
4. Undo the four screws of the connector panel.
5. Push the cover plate towards the connector panel until it fits
into place.
6. Finally fix the cover plate together with the connector panel
using the four screws.
Fig. 4: Installing the fixed cable connection
NL4 connection with cover plate
The two NL4 connector sockets of the cabinet's connector panel
are located in a recess to allow the use of the cover plate [1]
together with NL4 cable connectors, as shown in the graphic
opposite.
Note: Neutrik NL4FC type connectors must be used for this
option.
The cover plate is equipped with two knockout openings to allow
daisy chaining of the loudspeaker.
To use the NL4 connection, proceed in the same manner as
described above in the section entitled Þ "Fixed cable
connection" on page 6.

WR option (Weather Resistance)
A number of d&b loudspeakers are available in special options
suitable for different types of installed applications and
environmental conditions. The following options are available for
the 18S-SUB loudspeaker:
▪ Weather resistant (WR): This option is suitable for outdoor use.
The cabinets have an impact and weather protected black PCP
(Polyurea Cabinet Protection) finish.
WR cabinets are equipped with a recessed connector panel
including a Faston type connector (2 x 6.3 mm, female). A cover
plate which accepts single or dual PG cable glands (Type PG13.5
for cable diameters from 6 - 12 mm) is enclosed, as shown in the
graphic opposite.
NOTICE!
The WR option enables operation of loudspeakers in changing
ambient conditions, however it is not intended to enable
permanent, unprotected operation of loudspeakers outdoors.
▪ Provide an additional cover over the loudspeakers.
▪ Aim the cabinets either horizontally or with a downward tilt.
To install the fixed connection cable, please proceed as follows:
Tools required: Screw driver (#T20).
Note: Observe the correct polarity of the cable
Brown (+) / Blue (—).
1. Insert the connection cable through the PG screwing and
connect the male connector to the female connector.
2. Push the cover plate towards the connector panel until it fits
into place.
3. Fix the cover plate to the connector panel using the four
countersunk screws.
