A loudspeaker enclosure is just a cabinet built to carry sound to the listener via mounted loudspeaker drive units. The significant job of the loudspeaker enclosure is to prevent the out of phase noise waves of their rear of this speaker from combining with the Inphase sound waves from the front of the speaker. This ends in port patterns and cancellation, inducing the efficacy of the speakers to be paid off; specially from the low frequencies where the wavelengths are so large that interference can change the entire listening area.

Many loudspeaker enclosures utilize some sort of structure, similar to a box to comprise the out of phase sound energy. The box is made of wood or, even more recently, vinyl, both for its reasons of easy construction and appearance. Loud speaker cabinets are occasionally sealed and sometimes ported. Ported cabinets allow some of the sound energy inside the cabinet must be discharged, and if designed correctly with appropriate attention to phase relationships, both increase bass response and reduce motorist journey.

A number of other technology variations on the basic box design exist, such as acoustic lines. Enclosures always play a significant role in sound production along with the planned design impacts, adding unfortunate resonances, diffraction, as well as other unwelcome phenomenons.

Bass Reflex or vented loudspeaker enclosure

Vented or bass enclosures require special constructions due to the huge forces which can be developed by the drivers installed inside that behave upon them. Vented loudspeaker enclosures have two main purposes - the rest of vibrations from front and back of the loudspeakers, and the containment of atmosphere to ensure that the air can act as a resonating elastic medium in the enclosure.

Vented enclosure operation is analogous to how a bottle will probably behave as a whistle. In a tuned system it is crucial to avoid air leaks, since the vent produces the majority of the sound at the frequency of the pressure inside the enclosure can be significant.

Hydraulic Enclosures flows in the seams or walls of the enclosure can create the pruning of this device to shift in frequency, producing other undesirable effects also. The material utilized for enclosure walls should be sturdy and compact and should be free of voids or warps. The perfect loudspeaker enclosure might have no wall space in frequencies that fall over the frequency assortment of loudspeakers mounted init. 25 mm solid lead plate could create an superb loudspeaker enclosure.

Woofer and subwoofer enclosures

Enclosures employed for woofers and subwoofers could be satisfactorily modelled at the low frequency region, approximately 100 to 200 Hz and below using acoustics and the lumped component version. Electrical filter theory has been used with substantial success for woofer and subwoofer enclosures.
