Modelling speaker cabinets
The accurate amp models can be paired with speaker cabinet models of the
same quality. 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 of tube amps.
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 interac-
tion 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.
