2.1 Product description
The T-SUB is the subwoofer for the T-Series. It can be used to
supplement T10 cabinets in various combinations, either flown or
ground stacked. The T-SUB cabinet is an actively driven bass-reflex
design housing a long excursion 15" driver, its frequency response
extending from 47 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 cabinet is protected by a rigid metal grill backed
by an acoustically transparent foam. The cabinet top panel
incorporates a handle.
T-Series rigging components and arrays
Cabinets are mechanically connected using the rigging strands on
both sides of the cabinet front and a central strand at the rear of
the cabinet. All necessary rigging components are mounted to the
cabinet and are folded or slide out when needed.
A detailed description of the T-Series rigging components is given
in the T-Series Rigging manual which is provided with the Z5370 T
Flying frame.
A detailed description of planning and designing T arrays is given
in the technical information "TI 385 d&b Line array design,
d&b ArrayCalc" which is also provided with the T Flying frame.
The d&b ArrayCalc simulation software can be downloaded from
the d&b website at

2.2 Connections
The cabinet is fitted with NLT4 F/M connectors. All four pins of
both connectors are wired in parallel. It uses the pin assignments
2+/2–. Pins 1+/1– are designated to TOP cabinets. Using one as
the input, the second 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

d&b LoadMatch
With the d&b four channel amplifier platform, 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.
