2.1. Product description
Vi7P/Vi10P are passive 3-way loudspeakers housing two 10" LF
drivers, one horn-loaded 8" MF driver and a 1.4" HF compression
driver with a rotatable CD horn producing a nominal dispersion (h
x v) of 75° x 40° (Vi7P) or 110° x 40° (Vi10P), respectively.
All components are arranged symmetrically around the center axis
of the cabinet to produce a perfect symmetrical dispersion pattern.
This setup allows for a crossover design with a well defined
overlap of adjacent frequency bands resulting in a very consistent
and accurate vertical dispersion. Due to the dipolar arrangement
of the low drivers, broadband vertical dispersion control is
maintained down to approximately 350 Hz – an outstanding
feature for a passive 3-way system.
The frequency response extends from 59 Hz to above 18 kHz.
The cabinets are constructed from marine plywood and have an
impact and weather protected PCP (Polyurea Cabinet Protection)
finish. The fronts of the loudspeaker cabinets are protected by a
rigid metal grill backed by an acoustically transparent foam.
The cabinets are fitted with two M10 threaded inserts each on the
top, bottom and rear panels to accept either:
–
the Z5383 VP Mounting bracket,
– the Z5384 VP Flying adapter,
– or the Z5384 VP Flying adapter.
In addition the Q9032 Safety eye bolt M10 can be used to apply
an independent secondary safety device.
2.2. Connections
The cabinets are fitted with a pair of NL4 M connectors and a two
pole screw terminal block (ST). All four pins of both NL4 M
connectors are wired in parallel. The cabinets use the pin
assignments 1+/1–. Pins 2+/2– are designated to active
subwoofers.
Cabinets with the weather resistant option (WR) are equipped with
a fixed input cable (PG type, H07-RN-F, 2 x 2.5 mm
