JBL 4660

Commentary

This SR speaker system adopts a unique shape.

The 4660 is controlled in small halls, conference halls and event halls so that uniform sound pressure levels can be obtained in every corner of a square room, and has a special directional characteristic.

The high-frequency range is equipped with a horn type unit that combines a differentiated coverage horn and 2425J.
The Differentiated Coverage Horn is uniquely shaped and is designed to have a deformed pattern of 110 ° to the front and 38 ° to the rear of the room, which creates a square coverage area on the floor when suspended slightly from the ceiling, allowing a single speaker to cover a space that would otherwise require three or more high-band horns with a conventional speaker.
The service area is based on a square area with a width to depth ratio of 2 : 2.75. However, you can adjust the hanging angle of the speaker to accommodate various size ratios.

Equipped with 38 cm cone type woofer 2225H in the low range.

The enclosure uses a bass-reflex design with a front-mounted woofer layout to ensure good frequency balance in the back of the room.
