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 ...
To 129.55.27.4, who changed the transformer information: Transformers do not act as lowpass filters. They block DC voltages. 70V transformers result in a lack of low frequency information. High frequency information is not affected. Revision undone. 74.92.147.125 19:17, 26 March 2008 (UTC) Actually, you're both right.
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 back EMF and thus with the applied frequency.
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]
The transformer is almost always specific to a particular electrostatic speaker. To date, Acoustat and Beveridge built the only commercial "transformer-less" electrostatic loudspeaker. [ citation needed ] In this design, the audio signal is applied directly to the stators from a built-in high-voltage valve amplifier (as valves are also high ...
