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
