JBL 4325

Commentary

A monitor speaker made with almost the same standard as 4320.

A 38 cm cone type woofer 2216B (16 Ω) developed for the 4325 is mounted in the low range.

A horn type tweeter composed of a driver 2420 and a horn lens 2391 is mounted in the high range.
The 2420 uses a 0. 05-mm-thick duralumin alloy diaphragm to achieve wide-band reproduction of more than four octaves, and a pure silver impedance control ring to increase radiation efficiency to the highest audible frequency range.
The driver is equipped with a horn lens 2391 to improve directional characteristics. The 2391 consists of 11 inclined plates arranged at a 38 ° angle with 6.3 mm spacing, and the front face of the lens has an accurately calculated hyperbola.

The network section uses 3120 with a crossover frequency of 1.2 kHz.
The 3-position attenuator allows you to change the output level of the driver.
