2.1. Product description

The 4S and 5S cabinets are light-weight 2-way passive

loudspeakers using coaxially mounted, wide dispersion dome

tweeters. The coaxial design offers a symmetrical dispersion

pattern in the horizontal and vertical plane while the cabinets may

be mounted in either attitude.

The 4S employs a 4” neodymium LF driver in an ultra-compact,

sealed enclosure. Its frequency response extends from 130 Hz to

20 kHz.

The 5S comprises a 5” ferrite LF driver in a bass-reflex enclosure

covering the range from 80 Hz to 20 kHz.

Both systems can be used stand-alone or supplemented by

different subwoofers of the xS-Series.

The enclosures are injection molded with an impact resistant black

paint finish. The fronts of the loudspeaker cabinets are protected

by a rigid metal grill backed by an acoustically transparent foam.

The 4S and 5S rear panels incorporate two M8 threaded inserts to

accept the Z5401 Wall mount S. Using the M10 socket of its ball

joint adapter, the loudspeakers can be connected to different d&b

mounting accessories such as:

– Z5029 TV spigot,

– Z5034 Stand adapter,

– E6532 Super Clamp,

– Z5035 M10 to 3/8" adapter.

Intended use

Both cabinets are weather protected and suitable for outdoor use.

For unprotected outdoor operation the screw terminals must be

used for connection and the cover panels to hide the connector

panel (IP34, vertical aiming from +15° to –45°). A detailed

description of how to apply the fixed cable connection is given in

the following section (Þ Chapter 2.2. "Connections"

on page 5).

For this purpose the 4S cabinet must be installed with the M8

inserts located at the top of the cabinet's rear panel.

2.2. Connections

The cabinets are fitted with a pair of NL4 connectors and a two

pole screw terminal block (ST - cross-section up to 4 mm

AWG 11). All four pins of both NLT4 connectors are wired in

parallel. The cabinets use the pin assignments 1+/1–. Pins 2+/2–

are designated to active subwoofers.

Pin equivalents of the applicable connector options are listed in the

table below.
