d&b 4S - Manual (Page 5)

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
2 /
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.
