What is the difference between a cabinet (cab) and an amplifier (amp)?
A speaker cabinet (often referred to as a “cab”) is a standalone enclosure that houses one or more speakers designed to produce sound. The cabinet itself does not amplify the sound, but rather converts the electrical signals from an amplifier into audible sound. Amplifiers, on the other hand, are responsible for boosting audio signals from instruments or other sources to a level that can drive the speakers in the cabinet.
In essence, the cab complements the amp to deliver a full sound. While some amplifiers come with built-in speakers, separate cabs allow for more versatility in achieving specific tonal characteristics and volume levels. Musicians often choose their cab based on how it interacts with their amp, tailoring their rig for optimal performance.
