How to choose home audio?

There are many things we can't live without, including relatives, air, water and sound. From the singing of birds to the noise of sirens, to the tinkling of pots and pans at home, to the chirping of babies. Of course, the family seems to be inseparable from the sound. From the combination home theater to the popular computer multimedia audio, to today's home background music and portable Bluetooth audio and so on. The form of sound is changeable, but it can not change the indispensable position of sound in home life. How should we choose our home stereo? Today I'll talk to you.

Check the shape, color and size of the speaker

Choose the speaker generally from the shape. A multimedia active sound, if the shape is smooth and smooth, the color is delicate and uniform, it will first give people a feeling of heartbeat. Then, on this basis, carefully check whether the joints of the speaker box are uniform and tight, and whether the shape, adjustment knobs, function keys and Jack positions are reasonably distributed. When observing, you can't miss any nuances, including the marks or patterns on the speaker. Only when it is exquisite, correct and clear can it show that this speaker is of high workmanship and first-class quality. Or open the speaker with the consent of the seller to check whether its internal parts and wiring are concise and reasonable.

Estimate the maximum output power of the speaker

If you select a pair of speakers from the process and shape, you can take it up and see how heavy it is, in order to estimate the maximum output power of the speaker. Generally speaking, the undistorted power of the speaker should be at least 20W + 20W, that is, 20W per channel. At present, the maximum output power of multimedia active speakers in the market is PMPO music power, which is an indicator of pure advertising effect. In fact, it should be marked with the maximum undistorted power, which is only 1 / 8 of the PMPO power value. We can estimate the actual maximum output power of the speaker according to the weight of the transformer and amplifier in the box.

Test the quality of low frequency

The low frequency produced by poor quality speakers can be deafening, but it is completely bloated, loose and thick, lacking a sense of hierarchy and firmness. A good low-frequency instrument should be clean, lively, well-organized and will not be muddy. Even various low-frequency instruments such as big and small drums, bass guitar and Piano bass can be easily distinguished. So don't be easily deceived by the sense of low frequency. Low quality low frequency is not as natural and comfortable as clean sound.

Test if vocals

Human voice is the most commonly heard voice, and its advantages and disadvantages are not difficult to detect. Pay attention to whether the human voice has an unusual nasal sound or the feeling of being pursed. The mid-range loudspeaker will make a lot of noise in this frequency band. The intermediate frequency noise is more serious than other frequencies, because most of the audible sound frequencies or music frequencies are concentrated in the intermediate frequency range, which will become an obstacle to replay for almost all kinds of music.
