JBL 3145

Commentary

A dividing network developed for 4-way.

The 3145 is a network used for JBL's studio monitor, and its input terminals and level controls are independent so that it can be incorporated into an enclosure.
Designed for 4-way use, only mid-range drivers are 16 Ω specifications.

We use highly reliable, professional grade, carefully selected parts such as non-inductive non-polar capacitors with large current capacity developed exclusively for networks, low-loss and low-distortion inductors precisely adjusted one by one, and large switches and resistors.

Equipped with continuously variable level control.

Equipped with a selector switch for 2-way multi-amplifier drive.
