Qi7
Fig. 1: Qi7 loudspeaker
The Qi7 is the installation version of the Q7 loudspeaker. It is
acoustically compatible with the standard road version differing only in
cabinet construction and mounting hardware.
The Qi7 is a 75° x 40° passive two-way loudspeaker. It houses 2 x 10"
LF drivers and a 1.3" HF compression driver with a rotatable CD horn
and a passive crossover network. Its frequency response extends from
60 Hz to above 17 kHz. The two 10“ neodymium LF drivers are
positioned in a dipolar arrangement providing exceptional vertical
dispersion control even at lower frequencies.
The Qi7 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 Qi7 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.
