| A second manufacturer supplied an 18" speaker for evaluation that exceeded the expectations of the engineers at Thomas Organ. It offered distortion-free bass guitar response at high volume levels. This manufacturer, Vega Electronics, got their first big break by supplying the 18" speaker to Vox for Westminster bass amp production.
Over time, Vega Electronics became to be known as "Cerwin-Vega." The legendary Cerwin-Vega "Earthquake" 18" sub woofer enclosure remains in production today.
V418 and V4182 Westminster Cabinets
Thomas Organ offered a V418 and a V4182 version of the Westminster single 18" speaker cabinet. Both shared the same rear ported enclosure.
The V418 version of the Westminster speaker included a four ohm loudspeaker and was offered with the V118 and V1181 Westminster amp heads. These amp heads were both rated 60 watts RMS, 120 watts peak at four ohms.
The V4182 Westminster speaker included a two ohm loudspeaker and was combined with the V1182 Westminster amp head. The V1182 head, introduced in early 1968, was rated 120 watts RMS, 240 watts peak at two ohms. The two ohm V4182 Westminster cabinet allowed the V1182 head to offer all of the output power it was designed to produce.
Cabinet Construction
The Westminster enclosure was constructed of 1" thick particle board. A chrome plated tubular roller trolley was included with the cabinet.
