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. Constant-voltage speaker system - Wikipedia

   en.wikipedia.org/.../Constant-voltage_speaker_system

   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 ...

4. Damping factor - Wikipedia

   en.wikipedia.org/wiki/Damping_factor

   In loudspeaker systems, the value of the damping factor between a particular loudspeaker and a particular amplifier describes the ability of the amplifier to control undesirable movement of the speaker cone near the resonant frequency of the speaker system. [3]

5. Audio system measurements - Wikipedia

   en.wikipedia.org/wiki/Audio_system_measurements

   Music power has been making a comeback in recent years. See also Audio power. Power specifications require the load impedance to be specified, and in some cases two figures will be given (for instance, the output power of a power amplifier for loudspeakers will be typically measured at 4 and 8 ohms). To deliver maximum power to the load, the ...

6. Nominal watt - Wikipedia

   en.wikipedia.org/wiki/Nominal_watt

   This permits a loudspeaker to be used with an amplifier having a low internal impedance and a flat frequency response is realized for the combined amplifier/loudspeaker system. However, an amplifier with a low internal impedance delivers more electrical output power when the load impedance reduces (until the impedances become approximately ...

7. Electrical characteristics of dynamic loudspeakers - Wikipedia

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

   The electrical signal generated by the coil travels back along the speaker cable to the amplifier. Well-designed amplifiers have low output impedance so that this generated signal has minimal effect on the amplifier. Characteristically, solid state amplifiers have had much lower output impedances than tube amplifiers. So much so, that ...

9. Thiele/Small parameters - Wikipedia

   en.wikipedia.org/wiki/Thiele/Small_parameters

   A common use of Thiele/Small parameters is in designing PA system and hi-fi speaker enclosures; the TSP calculations indicate to the speaker design professionals how large a speaker cabinet will need to be and how large and long the bass reflex port (if it is used) should be.
