  2. Audio power - Wikipedia

    en.wikipedia.org/wiki/Audio_power

    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).

  3. Audio power amplifier - Wikipedia

    en.wikipedia.org/wiki/Audio_power_amplifier

    Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus 1 Hi Fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.

  4. Nominal watt - Wikipedia

    en.wikipedia.org/wiki/Nominal_watt

    The actual electric power may vary from about twice the nominal power down to less than one tenth. Loudspeaker efficiency is measured with respect to nominal power in order to emulate the situation outlined above where a low internal impedance amplifier is used with a loudspeaker. The convention is to supply one nominal watt during testing.

  5. Electrical characteristics of dynamic loudspeakers - Wikipedia

    en.wikipedia.org/wiki/Electrical_characteristics...

    This frequency is known as the free-space resonance of the loudspeaker and is designated by F s. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity. The back EMF generated by this movement is also at its maximum. The electrical impedance of the speaker varies with the ...

  6. Constant-voltage speaker system - Wikipedia

    en.wikipedia.org/wiki/Constant-voltage_speaker...

    Constant-voltage speaker systems are also commonly referred to as 25-, 70-, 70.7-, 100 or 210-volt speaker systems; distributed speaker systems; or high-impedance speaker systems. In Canada and the US, they are most commonly referred to as 70-volt speakers. In Europe, the 100 V system is the most widespread, with amplifier and speaker products ...

  7. Powered speakers - Wikipedia

    en.wikipedia.org/wiki/Powered_speakers

    An active full-range loudspeaker. Powered speakers, also known as self-powered speakers and active speakers, are loudspeakers that have built-in amplifiers.Powered speakers are used in a range of settings, including in sound reinforcement systems (used at live music concerts), both for the main speakers facing the audience and the monitor speakers facing the performers; by DJs performing at ...

  9. Thiele/Small parameters - Wikipedia

    en.wikipedia.org/wiki/Thiele/Small_parameters

    The 1925 paper [1] of Chester W. Rice and Edward W. Kellogg, fueled by advances in radio and electronics, increased interest in direct radiator loudspeakers. In 1930, A. J. Thuras of Bell Labs patented (US Patent No. 1869178) his "Sound Translating Device" (essentially a vented box) which was evidence of the interest in many types of enclosure design at the time.
