Page: 5 / 11

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

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
