d&b V8 - Manual (Page 5)

2.1. Product description
The V8 is a line array loudspeaker for medium to large-scale sound
reinforcement. When the V Flying frame is used, up to 24 cabinets
can be flown in vertical columns producing an 80° constant
directivity dispersion pattern in the horizontal plane.
The V12 line array module is acoustically and mechanically
compatible with the V8 and provides a 120° horizontal
dispersion.
The V8 cabinet is a passive 3-way design housing 2 x 10"
neodymium LF drivers, one horn-loaded 8" MF driver, two 1.4" exit
HF compression drivers with 2.5" diaphragms mounted to a
dedicated wave shaping device and a passive crossover network.
The wave segments of each cabinet couple without gaps and sum
up coherently. Splay angles between adjacent cabinets can be set
in the range from 0° to 14° with a 1° resolution.
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 horizontal dispersion. Due to the dipolar
arrangement of the low drivers broadband horizontal dispersion
control is maintained down to approximately 250 Hz - an
outstanding feature for a passive 3-way system.
The frequency response extends from 67 Hz to above 18 kHz.
The cabinet is constructed from marine plywood and has an impact
and weather protected PCP (Polyurea Cabinet Protection) finish.
The front of the loudspeaker cabinet is protected by a rigid metal
grill backed by an acoustically transparent foam. Each side panel
incorporates a handle while two additional recessed grips are
provided at the rear bottom of the cabinet.
V-Series rigging components and arrays
V-Series arrays may consist of a combination of V8 and V12
loudspeakers and/or V-SUB cardioid subwoofers.
Cabinets are mechanically connected using the rigging strands on
both sides of the cabinet front and a central strand at the rear of
the cabinet. All necessary rigging components are mounted to the
cabinet and fold out or slide out when needed.
A detailed description of the V-Series rigging components is given
in the V-Series Rigging manual which is provided with the V Flying
frame.
A detailed description of planning and designing V arrays is given
in the technical information "TI 385 d&b Line array design,
d&b ArrayCalc" which is also provided with the V Flying frame.
The d&b ArrayCalc array calculator can be downloaded from the
d&b website at www.dbaudio.com .
