What is the difference between 100V capacitor and 200V capacitor (used in frequency divider)
There should be no difference. The capacitance in the divider is basically about capacity
The same specifications, high voltage withstand, large volume, good insulation performance.
When using, if the conditions permit, choose the capacitor with high withstand voltage as far as possible.
What's the difference between 50V and 200V Loudspeaker Capacitor ?
They are different in withstand voltage. In theory, 100V capacitor is higher than 50V power supply. The general use allowance is 80-90%
Therefore, the power supply with 100V capacitor may be more than 80V
Using 50V may be about 40-45V

Capacitor is the simplest frequency division filter in car audio.
What is the function of WEET Audio capacitors? We have learned from high school that one of the functions of capacitors is to pass high frequency resistance to low frequency.
That is to say, let the high-frequency signal go to the high-frequency loudspeaker, and filter out the low-frequency signal.
There are two benefits to this:
One is to reduce the distortion of loudspeaker output. Because the frequency response of the tweeter determines that it is only effective for high-frequency signals, but not for low-frequency signals.
If there is no such filter capacitor, the low-frequency signals will be sent to the high-frequency speakers, and the high-frequency speakers will produce distortion to the low-frequency signals.
The second is power distribution. Generally speaking, the treble horn is smaller and can not bear more power, while most of the power of audio signal is at low frequency (the vibration amplitude is large at low frequency).
Without this filter capacitor, all the signals go into the high pitched loudspeaker, which may not be able to bear and burn out.
The capacitors have numbers of kinds, such as MKP, MKS, MKT, MKC and PET, but MKP is the best,
The temperature intensity of MKP is higher than that of MKS, but its temperature stability is slightly worse than that of MKS.
The biggest disadvantage of MKS is poor heat resistance, the limit is only 75 ℃, while MKP is 100 ℃.

WEET WMH Pure Aluminum Foil and Film Metallized Polypropylene Capacitors Reviews:
Sound: The physical size and shape of the WEET WMH is very similar to that of the Alumen Z-Cap 100VDC and Cicada Pure Aluminium Foil 100VDC. The WMH has a clear top end, more detailed than that of the Alumen Z-Cap but therefore less smooth. The Alumen's smoother nature makes it sound more intimate in a direct A-B comparison. Furthemore the Alumen had better depth, imaging and a slightly richer tone. Compared to the Cicada Pure Aluminium Foil the WMH Aluminum Foil and Metallized Polypropylene is far more open and clear, it just sounds less closed-in. If we go to a different breed of capacitors from the Mundorf stables the Supreme Classic sounds less mature than the WMH although it does have a similar amount of clarity in the top end. Vocal with the WMH have more richness making the Supreme Classic sound a little forward, a little more in your face. From Mundorf's EVO range, the Supreme EVO Oil also lacks a little overview compared to the WMH. But if we go up the Mundorf scale to the Supreme EVO Silver Gold Oil we get far better reverberation information and heaps more low level detail. This makes the Supreme EVO Silver Gold Oil keep the overview in complex orchestral music where the WMH tends to get muddled up. In direct comparison the WMH sounds rather bland.Maybe not quite at the same level as the higher grade Mundorfs but still a reasonably neutral and very usable capacitor.
Verdict: 11

For easy reference, we would like to list WEET hot and common pure Aluminum Foil and Polypropylene Film Audio Capacitors values as below.
WEET WMH is cross to the Alumen Z-Cap (pure aluminum foil capacitors) , whicg was especially designed for the tweeter and mid-section of crossovers for passive hi-fi speakers.

How people comment about WEET WMH aluminum foil and film capacitors (Pure Alucaps) and sharing a review ?
From the MKT film capacitor to the aluminum foil and film capacitor, all of a sudden people have the feeling of returning from fairyland to the human world, which is more practical. The sound density of the aluminum foil capacitor is also very high, and the sound fullness is better than that of the MKT film capacitor (maybe the sound is loose and gives people the illusion). The aluminum foil capacitor is not thick and dry. It has good transparency and music details. It has strong low-frequency bounce power, large amount of music information and strong music charm. The sound performance is also relaxed and natural. It is a very listening capacitor.
The tone is golden and soft. The intensity of the tone is better than that of the reference capacitor. The performance of the intermediate frequency is very pleasing to the ears. If you do not believe it , you can have a try.

There are several kinds of non-polar aluminum electrolytic capacitors.
The basic characteristics of the non-polar electrolytic capacitor have not been changed, but some measures have been taken in the structure, which can be used in reverse.
Whether it can be used in AC circuits and circuits with large ripple current depends on other properties, such as the temperature rise of capacitors, the impedance frequency characteristics of capacitors, etc.
According to different uses, there are many types of non-polar aluminum electrolytic capacitors. The following introduces several small non-polar aluminum electrolytic capacitors with different characteristic levels.
1) Non polar aluminum electrolytic capacitor. Here "general" means that there are no other measures except for the oxide film on both poles.
Its electrical properties are similar to those with polarity, and have the characteristics of small volume and large capacity. The capacitance error, loss tangent, DC leakage current and other indicators are similar to those of ordinary polar electrolytic capacitors. It is mainly used in the polarity conversion of DC or pulse circuit, such as color TV decoding circuit. At present, many manufacturers in China have this kind of capacitor (different series, different electrical performance indicators).
2) A non-polar aluminum electrolytic capacitor used for frequency division in audio circuits.
This is a special type of non-polar electrolytic capacitor,
it is different from the general non-polar electrolytic capacitor, the volume is slightly larger than the general type, the electrical performance index is also higher than the general type,
the capacitance error is small, the loss is low, and the DC leakage current is small.
As a frequency dividing capacitor, most of them are used at the frequency of 10-20KHZ. The frequency characteristics of wound electrolytic capacitors are also very important.

Is there any difference between ordinary electrolytic capacitor and audio frequency electrodeless bi-polarized and non-polarized capacitor?
Can the capacitance of loudspeaker treble be replaced by ordinary electrolytic capacitor? Is it different from that of audio frequency electrodeless capacitor?
The difference is that ordinary electrolytic capacitors have positive and negative polarity requirements, and can only work at lower frequencies.
However, the electrodeless bi-polarized and non-polarized capacitors of loudspeakers have no polarity requirements and can work at relatively high frequencies, such as 1KHz or 100Hz.
If you need them in emergency, you can connect the two same electrodes of two common electrolytic capacitors together, and the other two terminals are used as the two poles of the combined capacitor
