JBL 4866

Commentary

A speaker system for mid - and high-range reproduction of the concert series.

The 4866 is a long throw high-frequency speaker developed as part of a full-range multi-way suspended speaker array assembly.

Equipped with a front flat biradial horn (2386A) and a 4-inch titanium diaphragm (2445J), it is capable of transmitting clear sound even to customers far from the sound source due to its highly concentrated horizontal distribution distribution of 40 ° / vertical distribution of 10 °.

The enclosure is surface-treated with glass-fiber-reinforced plastic to ensure excellent durability. In addition, the top, bottom, and side surfaces are cut into a 15 ° tapered shape, and a fan-shaped array of 4860, 4863, 4847, etc. can be configured, so that it can be used for multi-way suspension.

Equipped with 8 embedded metal fittings for flying.

The Concert Series included a wide range of specialized options, including a carrying load case and various speaker mounting brackets.
