Product description

The ALi90 is the installation variant of the AL90 augmented array loudspeaker for medium scale sound reinforcement. When the AL Flyingframe is used, up to four cabinet modules can be flown in vertical columns producing a 90° constant directivity dispersion pattern in the horizontal plane. The ALi90 can also be applied as horizontal array of maximum four loudspeakers using the AL Flying adapter.  The ALi90 loudspeaker module is a passive 2-Way design housing two x 10" neodymium LF drivers and 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. Variable splay angles between adjacent cabinets can be set in a range of +/- 10° in 5° increments resulting in a total coverage of 50° up to 70° for two cabinets, up to a maximum of 150°per array. All components are arranged symmetrically around the center axis of the cabinet to produce a perfect symmetrical dispersion pattern. Broadband horizontal dispersion control is maintained down to approximately 370 Hz. The cabinet enclosure is constructed from marine plywood with an impact resistant black paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill backed by an acoustically transparent fabric. Three M10 threaded inserts are incorporated in one side panel to allow the secure attachment of a dedicated flying adapter.

Amplifiers

The d&b D20 and 30D amplifier can both be used to drive the AL60.
