JBL UT-025

Commentary

Tweeter system capable of 70 kHz ultra-high frequency reproduction.

The unit is equipped with a 2.5 cm hard dome type tweeter.
The diaphragm is made of sintered carbon graphite, which has ideal physical characteristics such as light weight and high hardness. This diaphragm material is made into a thin diaphragm which can respond quickly to minute input signals, thereby realizing ultra-high frequency reproduction.

Built-in high-pass filter circuit.
Three selectable cutoff frequencies of 12 kHz, 16 kHz and 22 kHz are available. To prevent contact loss due to changeover switches, a gold-plated large binding post-type multiterminal system is used.

The front baffle is made of 19 mm thick pure cherry natural wood and is used as the face plate of the dome unit.
In addition, the baffle surface is slanted upward to provide an offset angle between the baffle and the unit, and the directional characteristics are controlled by installing a short horn in the opening. Round processing is applied to the outer periphery of the baffle to prevent irregular reflection of sound at the edge.
