|The Vox AD120VTX combo amp was introduced at the 2003 Summer NAMM Music Trade Show in Nashville, TN. The AD120VTX replaced the AD120VT, an amp that had been first offered only two years earlier. The 2003 Vox product catalog dated "Summer 03" suggests that both the AD120VT and AD120VTX were initially offered concurrently.
The AD120VTX differed from the AD120VT in several ways. The most notable change was the replacement of the Celestion 7080 12" speakers from the AD120VT with the Celestion/Vox "Neo (or new) Dog."
The Celestion/Vox "Neo Dog" 12 inch speaker featured a neodymium magnet structure. The incredible magnetic properties of neodymium magnets mean that only a small amount of material is needed to produce the same flux as a much larger ceramic magnet structure. This offers a drastic savings in weight. The "Neo Dog" speaker weighs approximately one half of the weight of the Celestion 7080 it replaced without any loss of tone or power handling capacity.
The AD120VTX featured a plywood cabinet, the AD120VT had a medium density fiberboard cabinet.
The AD120VTX had an speaker impedance selector switch, the AD120VT did not. The impedance selector switch allowed the AD120VTX to operate at the full 60 watt x 2 output power at four, eight or sixteen ohm speaker loads.
This amp had followed the basic proportions of the Vox AC-30. Unlike the AC-30, the AD120VTX cabinet has a closed back.
