There are two types of speakers, electrostatic and electromagnetic, these two speakers have different appearances and qualities. Which one to use is up to the buyer, but if they don't know what the pros and cons of each are, it can be difficult to purchase one. Electrostatic speakers use a thin, flat diaphragm usually made of a sheet of plastic covered with a conductive material such as graphite sandwiched between two electrically conductive grilles, with a small air gap between the diaphragm and the grilles. For this speaker to operate without distortion, there must be a constant charge passing through the speaker rather than a constant voltage. The grids must be capable of generating a stable electric field, while allowing sound to pass through the stator plates (grids). To generate sufficient field strength, the audio signal on the grids must be at high voltage. The electrostatic construction is actually a capacitor, and current is only needed to charge the capacitance created by the diaphragm and stator plates. This type of speaker is therefore a high impedance device. Unlike the modern electromagnetic cone speaker, this is a low impedance device, with higher current requirements. The advantages of electrostatic speakers include distortion levels one to two orders of magnitude lower than conventional cone speakers in a package, extremely light weight of the diaphragm. which is covered over its entire surface. Since many electrostatic speakers are tall and thin, without an enclosure, they act as a vertical dipole line source. This results in quite different acoustic behavior in rooms compared to conventional electromagnetic speakers. Generally speaking, a large panel dipole in the middle of a paper......others distort the sound and in the worst case can sound like jumping into the song/sound. The best speaker that has been compared, among the two, the best speaker should be the electromagnetic speaker. This is because not only is the cost of replacing and purchasing this speaker cheaper, but also the sound quality it produces compared to electrostatic. Electrostatic loses in sound production because if there is too much vibration the outer casing can easily break and expose the electrical plates which if touched can cause harmful damage. Electromagnetic speakers are better than electrostatic. The magnetic speakers look very nice and produce a huge amount of sound and bass! These speakers can be placed anywhere to produce the desired sound quality, wherever they need to be placed..
