Speaker Models vs Cabinet Modeling
A Speaker Model is our proprietary method of taking a known, at and neutral guitar cabinet and through signal processing, we virtually "install" a
dierent speaker into it. Each speaker model is intended to sound like wiring up your cabinet with that guitar speaker.
You might say "But wait��� isn't that the same thing as cabinet model?" No! A cabinet model is a speaker cabinet that has a microphone placed over
one or more of its speakers, which is then typically run through a mic preamp and other post processing—similar to placing a mic on a cab in the
studio, which is then piped into the studio monitors or headphones (as in the following illustration)�
Instead, a speaker model takes an existing speaker, resonating in a cabinet, and only changes its frequency response to match that of a dierent
speaker. The result is, when standing in front, it still behaves like a traditional guitar amp, just with a dierent speaker. For the most authentic
experience, Powercab is designed to sound like a high-powered cabinet of the same size (1x12 or 2x12) rather than attempting to emulate the sound
of a larger (4x12) cabinet through a microphone and studio preamp�
