Qi subwoofer
The Qi-SUB is the installation version of the Q-SUB and can be
used to supplement Qi1, Qi7 and Qi10 cabinets in various
combinations, either flown or ground stacked. It is acoustically
compatible with the standard road version differing only in cabinet
construction and mounting hardware. The Qi-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 Qi-SUB cabinet is constructed from marine plywood and has
an impact resistant paint finish. The front of the loudspeaker cabinet
is covered with a replaceable acoustically transparent foam that is
then protected by a rigid metal grill. Four M10 threaded inserts on
each side panel of the cabinet enclosure are provided for attaching
installation hardware. Four rubber pads placed into their
recessed positions prevent movement of the cabinets when two
or more Qi-SUBs are stacked. The cabinet rear panel is fitted with
two NL4 connectors wired in parallel. The weather resistant (WR)
version comes supplied with a fixed cable.
Amplifiers
The Qi-SUB can be driven either by d&b's D6 or D12 dual channel power amplifiers configured for the Q-SUB.
More detailed information on specific loudspeaker setups with d&b amplifiers
is available either in the relevant loudspeaker or amplifier manuals.
