JBL 4560BKA

Commentary

Front load horn type enclosure which is an improved version of 4560.

The main change is that the upper baffle plate can be removed.
The removed upper baffle can be fitted with a 2370 by radial horn and a 2425J screwdriver to provide a relatively compact broadband system.

Equipped with 38 cm diameter woofer.

High-efficiency playback from 45 Hz to 800 Hz is possible. In the maximum loading band over 200 Hz, the efficiency is 6 dB higher than that of the direct radiation type. The directivity is 90 ° horizontal x 60 ° vertical.

The lower baffle plate seems to have changed around 1985 and the design is slightly different.

4560 BKS is a domestic type.
