Q-SUB Manual
The Q-SUB is the subwoofer for the Q-Series. It can be used to
supplement Q1 and Q7 cabinets in various combinations, either flown
or ground stacked. The Q-SUB cabinet is an actively driven bass-reflex
design housing a long excursion 18" driver, its frequency response
extending from 40 Hz to 130 Hz.
The Q-SUB cabinet is constructed from marine plywood and has an
impact resistant paint finish. The front of the loudspeaker cabinet is
protected by a rigid metal grill, covered with a replaceable acoustically
transparent foam. The cabinet incorporates a pair of handles, and
mounted on the rear panel are two EP5 or NL4 connectors wired in
parallel and four heavy duty wheels. An M20 threaded flange in the top
panel accepts the d&b Z5013 Loudspeaker stand for the deployment of
full range cabinets.
The Q-SUB has a total of 10 sockets in the front grill and side panels to
accept the Z5153 Locking pins 8 mm that connect to the array links of
the Q1 system. Two runners extend from the rear to the front panel of
the cabinet protecting the bottom panel against scratching. Two
correspondingly shaped recesses are incorporated in the top panel of
each cabinet that accept these runners to prevent cabinet movement
when stacking Q-SUBs.
CAUTION!
Only operate Q-SUB loudspeakers with a d&b amplifier configured for
the Q-SUB otherwise there is a risk of damage to the loudspeaker
components.
Connections
The Q-SUB cabinet is fitted with a pair of EP5 connectors. All five pins of
both connectors are wired in parallel. The Q-SUB uses the pin
assignments 3/4 and 5. Pin 5 is used for SenseDrive (only available
when using a D12 amplifier and 5-wire cabling). Pins 1/2 are designated
to Q-Series full range systems. Using the male connector as the input,
the female connector allows for direct connection to additional
loudspeakers.
The Q-SUB can be supplied with NL4 output connectors as an option.
The D12 SenseDrive function is not available when using NL4
connectors. Pin equivalents of EP5 and NL4 connectors are listed in the
table below.

Operation with D12
Selecting Q-SUB mode in the D12 enables up to two Q-SUB subwoofers
to be driven by the respective channel. In applications with low
continuous levels or low ambient temperatures up to three subwoofers
per channel can be connected.
Controller settings
100 Hz circuit
If the 100 Hz circuit is selected, the upper operating frequency of the
system is reduced from 130 Hz to 100 Hz.
