Professional audio technicians teach you how to choose high-quality speaker equipment.Bar audio bran

　　For the initial understanding of the speaker, it can be identified by the steps of "viewing, weighing, knocking, and recognizing": that is, first view the craftsmanship, secondly weigh the weight, thirdly knock the box body, and fourthly recognize the nameplate. Viewing the craftsmanship is to judge the quality from the first impression of the appearance of the speaker: the speaker made of natural logs is of course the best, but because of the high cost, it is often not recommended by the mainstream.

　　As mentioned above, there is usually a technical label on the back of the finished speaker: the content is nothing more than the frequency range, sensitivity, carrying power and impedance of the speaker. Among them, the sensitivity rate is an important indicator of the speaker box, which largely determines what kind of power amplifier should be selected for the box, how much power is needed to push it, and so on.

　　Another most important indicator is the frequency range. For example, the frequency range of the AE-10 two-way speaker is 50Hz to 20KHz, and 60Hz represents the extension value of the speaker in the low frequency direction. The lower the number, the better the speaker's low-frequency response: 20KHz represents the high-frequency extension that the speaker can achieve. The higher the number, the better the audio characteristics. Some speakers do not indicate this indicator, and the frequency extension range will become very wide.

　　First, listen to the characteristics. Generally speaking, good speakers will have their own unique sound characteristics. For example, the IQ-10 two-way speaker system under the GAEPro audio brand uses RCF units, and the sound field has a strong sense of surround. Compared with other ordinary speakers, this is beyond the reach of ordinary speakers.

　　A good speaker must have high hearing resistance. When listening to many speakers, the first listening will make the listener very happy, the sound is clean and the texture is good, but this does not necessarily mean that it is a good speaker. In the next period of time, perhaps the listener will find that its sound gradually loses its original color and becomes dry and tasteless. One of the experiences that GAEPro audio has concluded is that about speakers, it must be durable to be called a good speaker.
