Q7
Fig. 1: Q7 loudspeaker
The Q7 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 Q7 cabinet is constructed from marine plywood and has an impact
resistant paint finish. The front of the loudspeaker cabinet is protected
by a rigid metal grill, covered with a replaceable acoustically
transparent foam. The cabinet incorporates a pair of handles.
The Q7 cabinet is fitted with four types of rigging devices:
- Eight sockets in the front grill and rear edge bar that accept the
Z5153 Locking pins 8 mm to connect the array links.
- A quick lock adapter plate on one side of the cabinet that accepts
the Z5150 Q Swivel bracket or the Z5156 Q Flying adapter.
- Five sockets that accept the Z5048 Flying pin 10 mm to support
single cabinets and to secure the aiming of an array.
- Four M10 threaded inserts to accept the Z5020 Flying adapter 02,
Z5025 Flying adapter 03 or Z5043 MAX Horizontal bracket.
NOTICE: Only operate Q7 loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.

Fig. 2: Connector wiring
The Q7 cabinet is fitted with a pair of EP5 connectors. All five pins of
both connectors are wired in parallel. The Q7 uses the pin assignments
1/2. Pins 3/4 and 5 are designated to Q-SUB active subwoofers,
where pin 5 is used for SenseDrive (only available when using a D12
amplifier and 5-wire cabling). Using the male connector as the input,
the female connector allows for direct connection to additional
loudspeakers.
The Q7 can be supplied with NL4 output connectors as an option. Pin
equivalents of EP5 and NL4 connectors are listed in the table below.
