Cabinet Speakers

Speaker cabinets are specially engineered units in which audio equipment such as speakers and their associated hardware are mounted into. These cabinets can be very basic affairs, little more than a wooden case with no additional features other than one port for inputting a sound cable, or they can be incredibly complex cabinets with features ranging from numerous ports and internal baffles to acoustic insulation and composite materials used in their construction. The main point of housing loud speakers and PA speakers in cabinets is not simply to make them look neat and tidy, although that is one benefit. The cabinet actually provides a useful function in preventing competing sound waves from interacting with each other and distorting the end product. This is because the diaphragm that the speaker driver uses to create the sound we hear generates sound waves both at the front and the rear, and these will be out of sync with each other, thus creating a distortion if not dealt with adequately. Other side effects include echo and reverberation, as the sound waves would reach the audience at slightly different times as they travel on different paths through the loud speakers towards them. In addition to minimizing these unwanted side effects, loud speaker’s cabinets also help to manage the vibrations which are caused by the driver frame, as well as the buildup of heat that is associated with amplifiers, driver voice coils and other moving components in PA speakers.
