2.1. Product description
The B6-SUB is an actively driven, compact, high performance
subwoofer.
The cabinet houses a long excursion 18" neodymium driver in a
bass-reflex design. The frequency response extends from 37 Hz to
140 Hz.
The cabinet is constructed from marine plywood and has an impact
and weather protected PCP (Polyurea Cabinet Protection) finish.
The front of the loudspeaker cabinet is protected by a rigid metal
grill backed by an acoustically transparent foam. Each side panel
incorporates a handle and mounted on the rear panel are four
heavy duty wheels. An M20 threaded flange in the top panel
accepts a loudspeaker stand for the deployment of top cabinets.
Two runners recessed in the bottom panel prevent cabinet
movement and protect the bottom panel against scratching.
Correspondingly shaped recesses in the top panel of the cabinet
prevent cabinet movement when stacking B6-SUBs.
2.2. Connections
The cabinet is fitted with a pair of NLT4 F/M connectors. All four
pins of both connectors are wired in parallel. The B6-SUB uses the
pin assignments 2+/2–. Pins 1+/1– are designated to TOP
cabinets. Using the male connector as the input, the female
connector allows for direct connection to a second cabinet.
The cabinet can be supplied with NL4 M or EP5 connectors as an
option.
Pin equivalents of the connector options are listed in the table
below.

d&b SenseDrive
The SenseDrive feature within D12 amplifiers enables electrical
compensation for the properties of the loudspeaker cable used.
SenseDrive requires an additional sense wire. SenseDrive is
therefore only available with EP5 connectors and 5-wire cabling
for applicable loudspeakers.
Note: When the D12 is operated in "Mix TOP/SUB mode",
the SenseDrive function is available on the output B connector
only.
d&b LoadMatch
Starting with the D80 amplifier, the LoadMatch function enables
the amplifier to electrically compensate for the properties of the
loudspeaker cable used without the need for an additional sense
wire. For applicable loudspeakers, LoadMatch is therefore
independent of the connector type used.
