Guitar cabinets

 

— a cabinet is a separately made specialized speaker (speaker in a cabinet), designed primarily for use with a guitar amplifier (usually a separate “head” — see the relevant paragraph).

The cabinets do not have their own inputs for the instrument (with a few exceptions — and in such cases the speaker is used only to switch the signal to an external amplifier), power amplifiers — too, so such equipment is not designed for independent use in principle. And from more traditional acoustics, such speakers differ in additional optimization specifically for the sound of a guitar / bass (depending on the purpose). At the same time, the cabinet can have several inputs (see "Connection") and be used for several instruments at once — for example, solo and rhythm guitar at the same time.

Note that most cabinets have a fairly high power — from 100 W and above — and are intended mainly for concert use as part of a "stack" (a system of one or more speakers and a "head" amplifier installed on it).
