Q10 and Qi10 loudspeakers
The Q10 and Qi10 are full range loudspeakers. The Qi10 is the
installation version of the Q10 loudspeaker, it differs only in cabinet
construction and mounting hardware.
The Q10 and Qi10 are 110° x 40° passive 2-way cabinets
housing 2 x 10” LF drivers and a 1.3” HF compression driver
with a rotatable constant directivity horn and a passive crossover
network. The two 10” neodymium LF drivers are positioned in a
dipolar arrangement providing exceptional vertical dispersion
control with the 40° nominal angle being maintained down to
400 Hz.
Q10 and Qi10 can be used as stand-alone full range systems,
in combinations with other Q and Qi cabinets ground stacked
or mounted on a high stand. The wide constant directivity
performance provides remarkable transparency when used in
close proximity to listeners. It is also ideally suited to ambient and
distributed sound reinforcement tasks. When used in the upright
configuration the Q10 and Qi10 have a very accurate 110°
horizontal constant directivity behaviour that is maintained down
to approximately 800 Hz.
The Q10 and Qi10 cabinets are constructed from marine plywood
and have an impact resistant paint finish. The front of the
loudspeaker cabinets are covered with a replaceable acoustically
transparent foam and protected by a rigid metal grill. Four M10
threaded inserts on each side panel of the Qi10 cabinet enclosure
are provided for attaching installation hardware whilst the Q10
cabinet incorporates a pair of handles and has integrated rigging
hardware.
