AL60 Loudspeaker

The AL60 is an augmented array loudspeaker for medium scale sound reinforcement applications. The loudspeaker module is a passive 2-way design housing 2 x 10" neodymium LF drivers and one 1.4" exit HF compression driver with 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 a 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 directivity control of is maintained down to 550 Hz. The frequency response extends from 60 Hz to 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 fabric.
Each side panel incorporates a handle and three M10 threaded inserts are integrated in one side panel to allow the secure attachment of a dedicated flying adapter.
When the d&b Z5455 AL Flying frame is used, up to four loudspeakers can be flown in vertical columns producing a 60° constant directivity dispersion pattern in the horizontal plane.
AL60 cabinets can also be deployed as horizontal cluster of up to four cabinets using the d&b Z5456 AL Flying adapter or stacked with maximum of three cabinets using the d&b Z5458 AL Base plate.
