Most customers do not know how to screen
when choosing a car soprano. Are they selected according to size or material?
In fact, these are important factors to consider in the selection process, but
the key point is "power". Here we will introduce how to filter.
First of all, we should consider the power
and make clear the two indexes of the normally nominal power: the maximum power
and the continuous output power (RMS). Some customers are accustomed to using
the maximum power to judge the good and bad of a car soprano, which is a very
unscientific method of judging. The nominal value of the maximum power is the
power value which does not occur in physical damage or electrical damage in a
very short time (usually only a few milliseconds) without considering the
distortion. The continuous output power (RMS) is the power that can continue to
work steadily without distortion. Only this value can truly reflect the working
state of the horn.

Next, we should pay attention to the
selection of power. The continuous output power of the power amplifier is
smaller than that of the tweeter, which will easily cause the damage of the
car's tweeter. Because if the power output of the amplifier is 100W, when the
system is connected, once the volume knob is adjusted, the output power is
about 100W, and the power amplifier is at full load. The tweeter has a lot of
allowance. Once the user continues to increase the volume, the output power
exceeds the continuous output power of the power amplifier, that is the time
when distortion starts to happen. This distortion is known as "clipping distortion".
Even if the power is very small, such a distorted signal can generate electric
signals similar to DC, and it can easily destroy the voice coil.
So in order to ensure that the car
loudspeakers can be used normally, everyone in the purchase, will the power
factor in the first place, according to your actual needs to select the right
power, of course, but also in the process of the size, material and other
factors to consider in this to buy the most suitable car tweeter.
