The tweeter of a two-way speaker bears the important work of the entire high-frequency band. Its tweeter part of the speaker to bear all the power of the high-frequency part, in order to make this tweeter is not overloaded, so you can not choose a tweeter with a low crossover point, if you choose a low crossover point will lead to the tweeter on the tweeter will be through the very large power, which will lead to the tweeter is burned, under normal circumstances, the tweeter’s crossover point will not be more than 2,000 hertz!

The tweeter should also be used in conjunction with the woofer. At the same time, we also need to consider the tweeter’s low-frequency limit, otherwise, there will be a poor articulation of the two frequencies. 6.5-inch speaker’s high-frequency limit is generally not higher than 5,000 Hz, when we design the crossover point, if we leave a doubling of the frequency, then this crossover point of the reasonable take the value of about 2.5000 Hz, similarly, the low-frequency limit of the tweeter, if also according to the same leave a doubling of frequency to calculate, then it should be lower than 1.2500 Hz. Double the frequency to calculate, it should be lower than 1.2500 Hz.

For the requirements of the tweeter, first of all, the resonant frequency F0 can not be higher than half of the frequency of the crossover point, otherwise, it will lead to the crossover point in the position of the frequency response will be a problem, a reasonable range should be the resonant frequency of the speaker is not higher than 1.2500 Hz. If the supporting woofer size is less than 6.5 inches, at this point, the tweeter’s low-frequency limit will be slightly higher, because at this point the woofer’s high-frequency capability will be enhanced, the crossover point will be lifted, this is based on the characteristics of the woofer to decide!

When choosing the tweeter, we also need to pay attention to is the sensitivity, in principle the tweeter sensitivity can not be lower than the woofer sensitivity. If it is lower than it, it will be difficult to reduce the sensitivity of the speaker through some ordinary speaker attenuation, if the electronic crossover, this is not important, when the tweeter sensitivity is higher than the sensitivity of the bass speakers, we can through the tweeter on the series of some resistors consisting of some inhibitory facilities to reduce the two to achieve a perfect blend of treble and bass.

The last thing to point out is that the characteristics of the tweeter itself have a very big impact on the whole system, so we must go and pick the tweeter with lower distortion and good performance!
