Product description
The AL90 is an 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 AL90 can also be applied as horizontal array of maximum four loudspeakers using the AL Flying adapter. The AL90 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. 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 perfect symmetrical dispersion pattern. Broadband horizontal dispersion control is maintained down to approximately 370 Hz. The cabinet is 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.
