Isobaric loudspeaker in a cone-to-magnet (in-phase) arrangement. The image above shows a sealed enclosure; vented enclosures may also use the isobaric scheme. Two identical loudspeakers are coupled to work together as one unit: they are mounted one behind the other in a casing to define a sealed chamber of air in between them. The volume of ...
A bridge-parallel amplifier topology is a hierarchical combination of the bridged and paralleled amplifier topologies, with at least four single-ended channels needed to produce one bridge-parallel channel. The two topologies complement each other in that the bridging allows for higher voltage output and the paralleling provides the current ...
This is a popular modification for instruments with two single-coil pickups like the Fender Telecaster and the Fender Jazz Bass. For the former, special 4-way switches are available to replace the stock 3-way switch and provide a series wiring position. [27] Likewise, the two coils of a humbucker which are wired in series can be connected in ...
The large format line array has become the standard for large concert venues and outdoor festivals, where such systems can be flown (rigged, suspended) from a structural beam, ground support tower [2] or off a tall A-frame truss tower. [3] Since the enclosures rig together and hang from a single point, they are more convenient to assemble and ...
Bottom: bi-wiring. Loudspeaker bi-wired using banana plugs. Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the loudspeaker housing.
Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with 4-inch (10 cm) woofers and small tweeters designed for listening to music with a hi-fi system in a private home to huge, heavy subwoofer enclosures with multiple 18-inch (46 cm) or even 21-inch (53 cm) speakers in huge enclosures which are designed for use in ...
The most common three-phase system will have three hot legs, 208 V to each other and 120 V each to the neutral. An older, but still widely used, high-leg delta system uses three phases with 240 volts phase-to-phase for motor loads, and 120 volts for lighting loads by use of a center-tapped transformer; two of the phases are 120 volts to neutral ...
They are often described as two-way or three-way, which indicate, respectively, that the crossover splits a given signal into two frequency ranges or three frequency ranges. [2] Crossovers are used in loudspeaker cabinets , power amplifiers in consumer electronics ( hi-fi , home cinema sound and car audio ) and pro audio and musical instrument ...
