d&b audiotechnik will show the A-Series loudspeaker concept that combines advanced waveguide design with d&b enabling technologies at InfoComm 2022 in Las Vegas as booth #W2822. With flexible splay angles, this system is designed to address a wide range of medium size applications.
Realizing all the adaptability of a point source cluster with the extensive control options of a d&b line array, the system comprises the AL60 and AL90 loudspeakers, with ALi60 and ALi90 offering cabinets designed specifically for permanent installation.
Both loudspeakers share a passive 2-Way design featuring one 1.4” exit HF compression driver with a 3” diaphragm mounted to a wave shaping device, and two 10” neodymium LF drivers. The combination of waveguide design and the symmetrical dipolar arrangement of the LF drivers allows an overlap of the adjacent frequency bands in the crossover design. The wave segments of each cabinet couple without gaps and sum up coherently.
Using the appropriate frame, up to four AL60/AL90 loudspeakers can be flown either in vertical columns or horizontal clusters. Variable splay angles between adjacent cabinets can be set from 20° to 40° in 5° increments, allowing the finest of adjustments and ensuring sound is directed precisely where it’s wanted and nowhere else.
Midrange Directivity Control (MDC) ensures frequencies between 200Hz and 2kHz are evenly distributed, regardless of the splay angle. With its 60° horizontal directivity pattern the AL60/ALi60 can be maintained down to approximately 550 Hz, while its output capability can cover a distance of up to 100 feet depending on climatic conditions. The AL90/ALi90 – with its 90° horizontal pattern control down to 370 Hz – is both sonically and mechanically compatible, designed so that the same optimal acoustic result is achieved consistently anywhere, at any angle - whatever the configuration.
