Q, Qi and QiCSA subwoofers
Q, Qi and QiCSA-SUB are the dedicated subwoofers for the
Q and Qi loudspeakers respectively and can be used to
supplement the top cabinets in various combinations, either flown
or ground stacked. The Qi and QiCSA are the installation versions
of the Q subwoofer, they differ only in cabinet construction and
mounting hardware. They are actively driven bass-reflex designs
housing a long excursion 18" driver.
The subwoofers can be combined with the respective Q and Qi
loadspeakers in line arrays, as a separate column or in ground
stacked applications where the subwoofers also mechanically
support the top loudspeakers.
The Q, Qi and QiCSA subwoofer cabinets are constructed from
marine plywood and have an impact resistant paint finish. The
front of the subwoofer cabinets are covered with a replaceable
acoustically transparent foam and protected by a rigid metal grill.
The QiCSA-SUB cabinet has foams fitted to both the front and
rear sides of the cabinet, the grill facing backwards is fitted with
a single NL4 connector (see page 15). Four M10 threaded
inserts on each side panel of the Qi and QiCSA-SUB enclosure
are provided for attaching installation hardware whilst the Q-SUB
cabinet incorporates a pair of handles, an M20 threaded flange
in the top panel and has integrated line array rigging hardware.
