Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts.The electrical power delivered to the loudspeaker, together with its efficiency, determines the sound power generated (with the rest of the electrical power being converted to heat).
A passive radiator speaker uses a second passive driver, or drone, to produce similar low-frequency extension, or efficiency increase, or enclosure size reduction, similar to ported enclosures. Small [ 27 ] [ 28 ] and Hurlburt [ 29 ] have published the results of research into the analysis and design of passive-radiator loudspeaker systems.
In regard to notability, this is not intended to be an all-inclusive list; it is a list of manufacturers especially noted for their loudspeakers and which have articles on Wikipedia. To see more manufacturers, please refer to the category Loudspeaker manufacturers .
There are two types of monitors: passive monitors consist of a loudspeaker and horn in a cabinet and must be plugged into an external power amplifier; active monitors have a loudspeaker, horn and a power amplifier in a single cabinet, which means the signal from the mixing console can be plugged straight into the monitor speaker.
