Although any speaker has its strengths and weaknesses, especially on a limited budget, how to choose a value for the speaker is a great knowledge, because you want the horse and eat it too in case you want to make it strong and fat is really pains, but no matter for any speaker price and level for all there is a certain reference standards or guidance.

First, testing the quality of low frequency

The low frequency can be generated by the inferior speaker was deafening, but completely is the kind of bloated thick loose level feeling and strong sense of lack. The low frequency should be clean and crisp, clear, not muddy death dreams like, even though a variety of musical instruments such as the size of the low frequency bass guitar and Piano drums, bass, can easily distinguish. So don't be deceived by the feeling of low frequency, low frequency sound to the inferior as clean natural comfortable. Bookshelf type AV horn two sound road some heavy weight advertised, many buyers will think it is very value, because we will first choose horn weight, whether horn more the value of this statement is actually not, according to the speaker the heavier, dense plate of a box body (MDF or HDF) is thick, thick wood is not easy to produce resonance; another speaker is heavier, bass single magnet is bigger, so the bass is deep. But the average estimate of the speaker shelf type 38 cm high, the general weight of six or seven kg in weight should be even, if more than the weight of many, even as high as three, forty kilograms of weight, it may be a gimmick, the overall quality is not much help.

Two, test if the voice

The voice is the most commonly heard voice quality is not difficult to detect, pay attention to whether there is an unusual voice or sound a Minzui feeling. Some speakers of the "box" will also greatly interfere with the frequency, so that the voice of this band blurred. If colourations compared to other frequency noise pollution is more serious, because the most audible sound frequency, or frequency of music are concentrated in the intermediate frequency range, which is almost all kinds of music, will become the obstacle to play.

Three, test the high frequency of flexibility

Poor quality of the high frequency is ear piercing shriek, hear head headache, extreme case of the bel canto violin or soprano into sharp brake noise. Similarly, the high-frequency sound of different instruments have different texture, good high frequency sound can be resolved. The pros and cons of the high frequency can even make a difference from the two different years, different from the sound of the music played by the wood. The key is easy to grasp the high frequency sound is not good people listen and intimidating, pores erect, would not be heard the more tired, and should be soft and tough and elastic, smooth and high level to the highest point can easily hear no sound (of course not to tune the singer's for reference)

Four, test the high volume and sound field image

Some speakers were stable at low volumes, but the volume increase to a certain level will be distorted, or "shot", the emergence of various non recording music signal (of course with 12 points but volume as the test standard of safety). Specifically, if the string is one of the favorite types of music, you must pass this. To a certain extent, the speaker is in a certain extent, so that the sound is out of the box, create a clear sound field and the image, showing the location of the different musical instruments and texture. There are plenty of diffusion that can satisfy the existing listening space, piano and tail should be clearly heard, and in large volume and "bursting" without distortion, vocal and instrumental sound is not entangled. High quality playback can show the rich music sense and sense of air and the notes of spring, like clouds and see the blue sky, showing the detailed ordered video. More directly in long ears listen to not be tired.
