Custom Design for Vox - JBL D130/V90 Loudspeaker

Thomas Organ entered into a relationship with JBL Incorporated in 1967 that led to the optional factory installation of JBL D-120 speakers in V1143J Beatle Deluxe and V1133J Royal Guardsman amplifiers. It also led to the development of a high end, two-way PA enclosure named the V419 Vox Winston.

While the bass section of the Vox Winston was driven by two 16Ω JBL/Vox 15" D130/V90 speakers, the real star of the show was the trio of JBL components that powered the treble frequencies.

The JBL 375 mid/high frequency driver was unique in that it featured a large, two inch (5cm) throat exit and a four inch voice coil with edge wound aluminum ribbon wire. This allowed the 375 driver to offer the rare combination of unparalleled output and low distortion.

The 375 driver was mated to a JBL 5039 exponential horn that had a narrowly focused 60˚ H by 45˚ V "long throw" HF dispersion pattern. A removable JBL 2310 folded high frequency lens, mounted to the front of the 5039 horn with two thumb screws, increased the horizontal HF dispersion to 100˚ while decreasing "throw."

A JBL N1200 Frequency Dividing Network, mounted to the rear panel of the V419 Winston, provided a 1200hz crossover point between the 15" woofers and the mid/high frequency section.
