How to buy a Brand Speaker Guide in 2023

Speakers are actually relatively unpopular digital products, unlike mobile phones and tablets that are common in daily life. Even if you are not a professional, you still know a little bit about them. direction of purchase.

As for the purchase of speakers, most users are often confused, and the parameters on the official website are not very clear, and even if the parameters are similar, the timbre may not be the same.

Today’s article will simply popularize how to choose speakers, and which parameters of speakers are more important? Which brands of speakers are better? Which ones are good for desktop, living room, or home theater use? Which ones are more turbulent? Which ones are more prominent in human voice and more delicate and soft in tone?

Speaker selection direction and skills

1 In terms of material, it mainly depends on the speaker unit and the cabinet

The speaker, the most important core “processor” of the speaker, can be simply and roughly understood as the larger the size, the better

The cabinet, most of the cabinets are made of wood and plastic, and the low-end and high-end speakers are generally better with wooden cabinets

There are also some high-density plastics in the mid-range, which are not inferior to wood;

The common good speakers are mostly made of 18-25mm high-quality MDF particle boards, and the high-end ones are made of super-heavy solid wood such as red sandalwood and yellow pomelo or multi-layer composite rubber boards. Theoretically, the thicker the better, the denser the board. higher the better

2 In terms of parameters, focus on frequency response range, sensitivity, signal-to-noise ratio, distortion, rated power and impedance

Frequency response range: refers to the frequency range that the sound system can reproduce within the range allowed by the amplitude, and the amount of signal change within this range;

The flatter the frequency response curve, the better, and the higher the degree of reduction; the lower the lower limit, the better, preferably not lower than 20HZ; the higher the upper limit, the better, preferably not lower than 20KHZ

Sensitivity: The standard value is 89/90db, the higher the sensitivity, the better, the louder the output sound under the same power source

Signal-to-noise ratio: the difference between signal and noise frequency, the higher the value, the smaller the noise, the unit is db, the requirement of HiFi audio is ≥70db, most of the audio can meet

Distortion: The exact coefficient of music restoration, usually around 3%, of course, the lower the value, the better

Rated power: Theoretically, the bigger the better, but it should not be too big, too high power will also cause burnout, avoid using amplifiers with more than 200 watts for full power output,

That is, don’t let the speaker output at the highest volume for a long time; usually the main channel output reaches 120-150 watts to have better performance

Impedance: refers to the ratio of the signal voltage U input by the speaker to the signal current, in ohm Ω, the standard impedance of the speaker is 8Ω, usually the larger the value, the better

3 About sound channels, what do 2.0, 2.1, 5.1, 7.1 sound channels mean?

2.0 channel refers to two-channel stereo speakers, which are generally divided into: separate type and conjoined type in terms of form and structure. The separate type is a combination of two independent boxes, which are left channel and right channel speakers;

The conjoined type is that the left and right channels are placed in different positions on the same box to meet the stereo effect. This structure is generally a multi-functional portable stereo speaker; it is generally used in daily listening to songs, watching movies, and games.

2.1 channel is composed of a subwoofer and a pair of full-range speakers (satellite boxes) with weaker bass. There are also a few satellite boxes that can be made into two-way frequency. The effect of the bass depends on the size of the speaker; it is also used For everyday music, games

5.1-channel, refers to front and rear four surround + a center surround + a subwoofer, the entry level of stereo surround, suitable for home theater

7.1 channel, on the basis of 5.1 channel, add two side surrounds, high-end level stereo surround, for home theater

4 About monitoring and home multimedia speakers

Multimedia active speakers are common speakers on the market. They have relatively better sound saturation and more atmosphere. They are the sound after the sound has been modified, which is equivalent to “beautifying” the sound.
The monitor speaker is to retain the original sound to the greatest extent, without any modification or rendering, faithfully restore the audio signal, and restore the idea of the music producer. It is equivalent to full fidelity, more professional, and suitable for users who have extremely high requirements for sound restoration.
PS: It should be noted that monitoring is the same as HiFi, and most of the publicity does not match the reality. It is just marked with the word “monitor” and then the price is raised. In reality, the effect of monitoring cannot be achieved, so don’t pursue it blindly.
