B. Cabinet Models
Now let’s look at the CABINET models:
Cabinet and speaker accuracy
There’s not much point in having incredibly accurate amp models if the speaker cabinet models on offer aren’t of the same exacting standards. As
you may know, in real life, the output stage of a tube amp works in close harmony with the varying impedance curve of the speaker(s) it is driving.
This intimate and vital relationship plays a major role in producing the warm, punchy sound and pleasing feel that we all know and love. In a nut-
shell, modelling a speaker cabinet is not just a case of frequency response, but is a combination of frequency response, transient response (how a
speaker reacts to the strength of how a note is played), and the all-important interaction of the amps output to the speaker’s impedance curve. In
addition, other vitally important factors that have to be taken into account when modelling a cabinet are the actual physical dimensions of the
enclosure (cabinet), the unique tonality of said enclosure (which will be affected by both the type and thickness of the wood it is made of) and
whether it boasts an open, semi-open or closed-back design. Special circuitry and unique modelling technology ensures that all of these factors are
well taken care of in the cabinet models built into your JamVOX.
1. VOX AC15
This is a 1x12" open backed combo using the famed VOX Blue Alnico speaker, manufactured by Celestion in England.
2. VOX AC30
These original 2x12" VOX Blue Alnicos, are wired in series for 16 Ohms, and add even more of that great VOX tone.
3. VOX AD412
This cabinet is one of VOX’s latest products, and due to the fact we are extremely proud of it, and that it is without a doubt an exceedingly great
sounding cabinet, we just had to include it with our cabinet models. The cabinet itself features custom designed Celestion speakers using Neody-
mium magnets, one of the first, if not the first, cabinet to use this technology. It also uses some special cabinet acoustic design technology that is also
a first for VOX and 4x12s in general. Use it as a valid tonal option with any model, but especially the amp head models. We think you will like it!
4. VOX AD120VTX
This is a closed back cabinet containing two 12 inch custom-designed Celestion speakers with Neodymium magnets.
