2.1 Product description
The AL60 and AL90 are augmented array loudspeakers for
medium scale sound reinforcement applications providing a 60°
and 90° horizontal dispersion respectively.
Both loudspeakers are passive 2-way designs. They house 2 x 10"
neodymium LF drivers, one 1.4" exit HF compression driver with a
3" diaphragm 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 20° to 40° in 5° increments resulting in a total coverage of
50° up to 70° for two cabinets, with a maximum total coverage of
150° per array.
All components are arranged symmetrically around the center axis
of the cabinet to produce a perfectly symmetrical dispersion
pattern. This setup allows for a smooth crossover design with a well
defined overlap of adjacent frequency bands resulting in a very
consistent and accurate horizontal dispersion.
Due to the bipolar arrangement of the LF drivers, broadband
horizontal directivity control of 60°/90° is maintained down to
550 Hz/370 Hz respectively. The frequency response extends
from 60 Hz to 18 kHz.
The cabinets are constructed from marine plywood with 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 fabric.
Each side panel incorporates a handle, while one side panel is
equipped with three M10 threaded inserts to allow the secure
attachment of a dedicated flying adapter.
A-Series rigging components
When the d&b Z5455 AL Flying frame is used, up to four
loudspeaker modules can be flown in vertical columns producing a
60° or 90° constant directivity dispersion pattern in the horizontal
plane.
AL60 and AL90 can also be deployed as a horizontal cluster of
maximum four cabinets using the d&b Z5456 AL Flying adapter.
The d&b Z5458 AL Base plate allows ground stack setups of up to
three TOP cabinets, either as pure TOP ground stacks or placed on
top of applicable d&b subwoofers, such as the V-SUB or V-GSUB.
