A loudspeaker enclosure or loudspeaker cabinet is an enclosure (often box-shaped) in which (e.g., and ) and associated electronic hardware, such as and, in some cases,, are mounted.

Enclosures may range in design from simple, homemade rectangular particleboard boxes to very complex, expensive computer-designed cabinets that incorporate composite materials, internal baffles, horns, and acoustic insulation. Loudspeaker enclosures range in size from small cabinets with 4' woofers and small designed for listening to music with a system in a private home to huge, heavy enclosures with multiple 18' or even 21' speakers in huge enclosures which are designed for use in stadium concert for concerts. The primary role of the enclosure is to prevent sound waves generated by the rearward-facing surface of the of an open speaker driver interacting with sound waves generated at the front of the speaker driver. Because the forward- and rearward-generated sounds are out of phase with each other, any interaction between the two in the listening space creates a distortion of the original signal as it was intended to be reproduced.

As such, a loudspeaker cannot be used without installing it in a cabinet of some type, or mounting it into a wall or ceiling. Additionally, because the sound waves would travel different paths through the listening space, the sound waves in an unmounted speaker would arrive at the listener's position at slightly different times, introducing and effects not part of the original sound. The enclosure also plays a role in managing vibration induced by the driver frame and moving airmass within the enclosure, as well as heat generated by driver voice coils and amplifiers (especially where woofers and subwoofers are concerned). Sometimes considered part of the enclosure, the base, may include specially designed 'feet' to decouple the speaker from the floor.
