  2. Nominal impedance - Wikipedia

    en.wikipedia.org/wiki/Nominal_impedance

    The nominal impedance of the transmission line and of the amplifiers and equalisers in the transmission chain will all be the same value. [6] Nominal impedance is used, however, to characterise the transducers of an audio system, such as its microphones and loudspeakers. It is important that these are connected to a circuit capable of dealing ...

  3. Electrical characteristics of dynamic loudspeakers - Wikipedia

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

    The electrical impedance of the speaker varies with the back EMF and thus with the applied frequency. The impedance is at its maximum at F s, shown as Z max in the graph. For frequencies just below resonance, the impedance rises rapidly as the frequency increases towards F s and is inductive in nature. At resonance, the impedance is purely ...

  4. Line level - Wikipedia

    en.wikipedia.org/wiki/Line_level

    Instead, line level circuits use the impedance bridging principle, in which a low impedance output drives a high impedance input. A typical line out connection has an output impedance from 100 to 600 Ω, with lower values being more common in newer equipment. Line inputs present a much higher impedance, typically 10 kΩ or more.

  5. Nominal watt - Wikipedia

    en.wikipedia.org/wiki/Nominal_watt

    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. If the nominal impedance is 4 ohms, the voltage would be 2 volts.

  6. Thiele/Small parameters - Wikipedia

    en.wikipedia.org/wiki/Thiele/Small_parameters

    There are numerous methods to measure Thiele-Small parameters, but the simplest use the input impedance of the driver, measured near resonance. The impedance may be measured in free air (with the driver unhoused and either clamped to a fixture or hanging from a wire, or sometimes resting on the magnet on a surface) and/or in test baffles ...

  7. Characteristic impedance - Wikipedia

    en.wikipedia.org/wiki/Characteristic_impedance

    The input impedance of an infinite line is equal to the characteristic impedance since the transmitted wave is never reflected back from the end. Equivalently: The characteristic impedance of a line is that impedance which, when terminating an arbitrary length of line at its output, produces an input impedance of equal value. This is so because ...

  8. Damping factor - Wikipedia

    en.wikipedia.org/wiki/Damping_factor

    The loudspeaker's nominal load impedance (input impedance) of is usually around 4 to 8 Ω, although other impedance speakers are available, sometimes dropping as low as 1 Ω or 2 Ω. However, the impedance rating of a loudspeaker is simply a number that indicates the nominal minimum impedance of that loudspeaker over a representative portion of ...

  9. Loudspeaker - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker

    A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
