Vox Series 90 V130 Powered Speaker: Close Up
1969 - 1971

The V130 Series 90 powered speaker cabinet was a close cousin to the Vox V4141 Beatle cabinet offered by Vox from 1966 to 1968. Like the V4141 Beatle cab, the Series 90 V130 cab had four 12" Celestion Alnico "Silver" loudspeakers rated at 25 watts RMS each. Both featured two mid frequency horns, although the Series 90 V130 cab replaced the Goodmans Midax horns used in the V4141 Beatle cabinet with two similar but shorter horns made by Celestion. Both cabinets were the same size and shared the same tubular steel chrome plated swivel trolley.

Unlike the V1143 Beatle head and V4141 Beatle speaker cabinet it replaced, the audio output amplifier and power supply sections of the V130 were mounted to the floor of the closed back speaker enclosure. Assembling the amplifier in this fashion broke tradition with the conventional amplifier design concept that included the audio output amplifier, power supply, and control section circuits inside the amplifier head cabinet. As the V130 cabinet is mounted to a swivel trolley with casters, the additional mass of the audio output amp and power supply was shifted to "rolling" weight in the speaker enclosure rather than "hand carried" weight of the amp head.

Thomas Organ claimed a 140 watts RMS, 280 watts peak power rating for the V130 powered speaker cabinet at 4% total harmonic distortion at 1 kHz. While this might seem to be a slight increase of power over the 120 watt RMS, 240 watt peak power of the V1143 Beatle amp the V130 replaced, it probably wasn't. The 120 watt RMS power rating of the Beatle head was measured at 1% total harmonic distortion at 1 kHz. I believe Thomas Organ squeezed out the extra 20 watts of RMS power by allowing a 3% higher total harmonic distortion level in their V130 output power measurements.

The back of the V130 enclosure featured a recessed control panel, as seen above. The left side of the control panel included an octal socket that connected to a cable that was hard wired to either the V132 or V133 preamp heads. This socket served two purposes. It supplied operating voltages to the preamp head and received the audio signals sent from the preamp head back to the V130. The rear control panel also included a 1/4" input jack with a volume control (Vox suggested this could be used to amplify a tape recorder), a 1/4" output jack for a remote amp and a 1/4" output jack for a remote speaker. It also included a line reverse switch, red power indicator lamp, power switch, fuse holder, and 120 volt convenience outlet.

The AC power cord came out of the lower right corner of the back. A metal cord reel mounted on the enter of the back secured the AC power cord for transport.

Dimensions (less trolley) and Weight: 40" H x 27" W x 10.5" D, 125 pounds
