There are a variety of specialized capacitors for various applications. I will mention here only the most important categories seen in particular in terms of audiophiles. Capacitors are used in audio applications that are able to conduct electricity better and better as the frequency increases.
Types of capacitors:
Electrolytic capacitors, capacitors of high capacity at a lower volume used in oscillating circuit, or equalizer installed in parallel with the woofers as low-pass filter. There are variant polarized electrolytic capacitors; these circuits are used as filtering power sources, or as timers.
MKT (plastic film capacitors), high quality capacitors used in series and in parallel
environments such as speakers and band pass filter or in parallel with the woofers as low-pass filter.MKP (paper film capacitors), high quality capacitors used in series with the tweeters as the top pass filter in series or parallel environments such as speakers and band pass filter.
1. MKT capacitors are made of metallized polyester film. As quality and they range from
MKP capacitors and bipolar electrolytic capacitors. Loss coefficient of the capacitor MKT is 20 times higher than that of a MKP but 10 times smaller than that of a bipolar electrolytic capacitor. (MKP loss coefficient: 0.0002, MKT <0.006,) MKT capacitors can be considered as a class of bipolar capacitors. They are used both as a low pass filter in Hi-Fi and the low-pass or band pass filters in a filter circuit speaker.2. MKP capacitors are made of metallic foil and paper capacitors are considered audiofile. Basically these capacitors are "induction-free and have a very low loss factor, resulting capacitor is a very" fast. “MKP capacitors are the starting point of great finesse in musical reproduction. They are successfully used as a pass filters in series with the tweeters above or as a coupling capacity in lamps or transistor amplifiers.
