Qi1
Fig. 1: Qi1 loudspeaker
The Qi1 is the installation version of the Q1 loudspeaker. It is
acoustically compatible with the standard road version differing only in
cabinet construction and mounting hardware.
The Qi1 is a passive two-way loudspeaker. It houses 2 x 10" LF drivers,
a passive crossover network and a 1.3" HF compression driver with a
toroidal wave shaping device to achieve a 75° x 15° (h x v) dispersion
characteristic. Its frequency response extends from 60 Hz to above
17 kHz. The two 10“ neodymium LF drivers are positioned in a dipolar
arrangement providing an exceptional dispersion control even at lower
frequencies, with the 75° nominal dispersion angle being maintained
down to 400 Hz.
The Qi1 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.
NOTICE:
Only operate Qi1 loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.
Weather resistant (WR) option
NOTICE: The WR option enables operation of loudspeakers in changing ambient
conditions, however it is not intended to enable permanent, unprotected
operation of loudspeakers outdoors.
- Provide an additional cover over the loudspeakers.
- Aim the cabinets either horizontally or with a downward tilt.
