In audio circuit, how to connect the positive and negative electrodes of the capacitor? 
As output, the positive pole is connected to the output, and the negative pole is connected to the input. When the input is used, the negative pole is connected to the input and the positive pole is connected to the output. 
For example, the two pins and one pin of the amplifier are connected to the positive pole of the capacitor, and the negative pole is connected to the input signal and output signal respectively

Audio Note Oil Filled Mylar Capacitor. The black line marking on the capacitor’s body means the negative or input side. We can see the noise is quite big if we put the positive probe on the side which has black line marking.
Lower noise if we put on the probe on the opposite way，that is the outer foil side 

Mundorf Supreme Capacitor doesn’t have marking, so you must measure one by one to confirm.For sure, lower noise if we place the probe on the opposite way.
For WEET Copper foil capacitors, we have two ways to identify the outer foil side . Firstly, we will make a marking when winding the copper and MKP on the core. Secondly, we can  mark a line or a special symbol on the surface of the marking. By doing these two process, we will show customers, a clear way to connect the positive and negative electrodes of the capacitor to gain the best music sound.

Below is the core of our WEET copper foil capacitors with marking identification.

WEET WMW Pure Copper Foil Capacitor 0.68uF 100VDC exact replacement for Audyn True Copper Cap 1.0uF 630V Copper Foil Capacitor

Audyn's True Copper Cap line of capacitors is German-made to an exacting 2% tolerance using ultra-pure OFC (oxygen free copper) foil electrodes and a polypropylene dielectric. 

WEET WMW Pure Copper Foil Capacitor 0.68uF 100VDC with tolerance 3% and 5%. Mostly is 5%, as this kind of capacitor is very hard to make, almost is hand made.

This combination of capacitor materials provides a clean, neutral, "signal-in is signal-out" sound. No strange mixtures of various materials or, as the manufacturer says, "fairylike oils". The use of pure copper also reduces inductance for the greatest possible extension.

European users of the Copper Foil Cap capacitors regard them as spatially remarkable, great for imaging, and naturally balanced. Extract the best possible performance from your speakers' drivers, and hear everything on high resolution recordings. 

WEET's Pure Copper Foil Capacitor is also great for upgrading capacitors in the signal path of high-end audio components.

WEET WMW Condenser Capacitors - Bypassing vs. Film & Foil in Crossover Copper Foil Capacitors

Polypropylene & copper film & foil capacitor. An excellent standard audio capacitor, preferred by lovers of clean, accurate sound reproduction.

The WEET WMW Pure Copper Foil Capacitor will likely go through some combination of MKP and Foil film together, and some will likely proclaim it "the best capacitor," 

I do believe that after enough people have listened to it and enough time has passed, this capacitor will take a firm place among the pantheon of reference capacitors in the world. 

It artfully combines a high degree of resolution, musicality, color, spunk, and individuality while avoiding deal-breakers in terms of sound quality. 

The fact it costs much less than the European alternatives are what should warm the heart of audiophiles and encourage a personal audition. Good listening. You should have a try.

The WEET WMW Series is a super high-end pure copper foil capacitor, designed specifically for passive crossovers (mainly tweeters).

They are also equally well suited for mid-range application, but due to the price point of these super high-end capacitors, they will most often be used for tweeter application.

Capacitor is an indispensable part of many circuits and power equipment. Due to the different requirements in the circuit, different capacitors are needed, so capacitors can be divided into many different types. It can be divided according to many factors such as structure, material and function. MKP is one of them. What are the functions and characteristics of MKP capacitance? You might as well follow the professionals to learn about it.

MKP is the abbreviation of metallized polypropylene film capacitor, which represents the material of capacitor. Metallized polypropylene capacitor, small loss of lead out, small internal temperature rise, negative capacitance temperature coefficient, excellent flame retardant performance.

It is widely used in high-voltage and high-frequency pulse circuit, S-correction and line reverse stroke waveform in TV and display, electronic rectification absorption and SCR rectification circuit in lighting circuit. For safety regulation. It's also useful when RC depressurizes,

In addition, the metallized capacitor is made of polypropylene as the medium, and aluminum is deposited on the film by vacuum evaporation method. It is wrapped with insulating material and unidirectionally led out. It has excellent electrical performance and is suitable for DC and pulse circuits of electronic equipment.

There are many functions and characteristics of MKP capacitance. Let's talk about the characteristics of this kind of capacitor.

MKP capacitor adopts fully sealed rectangular metal shell with fixed plate at the bottom or both sides and ceramic insulator. And take a non inductive winding method, so the cylindrical metal aluminum shell, small volume, light weight. Relatively speaking, it has good electrical performance, small loss and good self-healing.

Not only that, the pressure explosion-proof device is installed inside, which is safe and reliable. It is usually used in AC power system, especially for special capacitor of air conditioner compressor and assembling power factor automatic compensation cabinet.

How much capacitance is the best for midrange speakers

——The selection of capacitor has a great influence on the sound playing of the midrange loudspeaker. It is not suitable to be too large or too small.

——In general, the capacitance of about 10 μF can be selected according to the law.

There are two choices of capacitors for midrange speakers:

1. Nonpolar capacitor with 4.7uF

2 connect two 10uF capacitor positive electrodes in series

If the mid tone loudness is low, increasing the capacitor's capacitance will only change the frequency division point, but not the loudness. In addition, blindly increasing the capacitance will increase the current of the midrange speaker (medium and low frequency current), which may burn out the midrange speaker when rated output!
