What exactly does a computer speaker 2 1 or 2 5 mean? Thank you!

The crossover design of the speaker, if the speaker unit of the main speaker and the satellite speaker is designed as a full-band speaker, then because there is only one speaker, the theoretical playback frequency range is 20Hz 20kHz, but it is difficult to do in practical applications, which may lead to insufficient midrange. However, the appearance of satellite speakers with this design is mostly small and beautiful. There is also a crossover design that uses a tweeter and a mid-bass speaker on the speakers of the main speaker and the satellite speaker, which can make the low, medium and high parts have better performance, but the appearance of this kind of speaker is generally not good-looking.

The channel design of the speaker. The speaker has two independent power amplifier modules, one is a module responsible for satellite speakers for stereo, one is a module for subwoofers dedicated to subwoofers, stereo modules are independent left (L) and right (R) channel power amplifier blocks, and the subwoofer is a slightly high-power power amplifier block after the combined filtering of the left and right channels. Because the heavy low sound is a joint filter,So there is a line disconnected in the left and right channels of the input,Another corresponding speaker will also emit a slight sound,This can be used to test the quality of the speaker,You can only connect a left or right audio input line,Listen to the volume of another satellite speaker is relatively large or small,The smaller the better,The change of heavy bass between one and two inputs,The smaller the better。

The pair of floor-standing speakers with wooden bases are not tall in walnut veneer, and the bass reflex hole is located in the middle of the back, and there are two sets of high-end bi-wire speaker terminals. The front baffle has only two units, and the treble is a Seas-specific 3 4-inch tweeter that many ProACs speakers use, and the unit is surrounded by soft sound-absorbing material that minimizes round-firing interference. The seven-inch low-midrange unit is amazing, and Proac says their speakers never used such a unit.

There are two amazing things, one is that its rubber suspension edge is well designed, and when the diaphragm is in long-distance motion, it can maintain a high degree of stability. The second is that the surface of this single surface is painted and furnished, which looks like some kind of paper texture, with very high hardness, and at the same time can emit a lot of energy. The monolithic arrangement is still Proac's consistent mirror symmetry, with the treble unit tilted inward, making it easy to achieve precise positioning.

As you can see from the reflex holes at the back, there is no much separation in the response's speakers, and the bass unit backwaves are projected almost immediately through the reflex holes. The sound-absorbing material is common glass wool, and I couldn't find a place where the Studio series used to fill sandbags or chalms. The structure is really simple, but the sound it sings is so good!

In the large space, I suspect that the frequency indicated by the response should be 20Hz-30kHz, and even in the six-ping-large listening room, its low frequency below 40Hz is no longer felt, and I think the Proac original factory probably underwrote a few negative DBs. The larger response, the low frequency specification is also not as low as 20Hz, which I guess is a label error.

It's two small speakers + 1 host,In fact, it's 2 speakers and a subwoofer It's 5 speakers and a subwoofer,But you need the motherboard to support the channel。

Two satellite speakers plus a subwoofer Other refers to x number of satellite speakers plus one subwoofer Like to listen to ** Buy Like to play games Buy.

Remember.

Wrong should be and two satellite speakers + one subwoofer Five satellite speakers + one subwoofer.

It's 2 stereos + 1 subwoofer, I don't know.

There are two types of speakers: a small bookshelf box and a large floor-standing speaker.

The characteristics of the bookshelf box are that the middle and high tones are better, and the bass frequency is not low enough (the speaker is small, and the small bass of the speaker is not deep), so the bookshelf box is suitable for listening to the bass frequency is not low, such as violin, erhu, guitar, pipa, guzheng and other string music, and listening to the human voice can also be.

For example, the frequency range of a 6-inch bookshelf box is 50-20,000 Hz, and 50 Hz is the lowest frequency of the bookshelf box (lack of subwoofer below 50Hz).

Floorstanding speakers due to the large volume of the speaker,The bass can dive to the lowest frequency of the speaker,So,Floor speaker appreciation**It's better,There are not many defects in frequency,Appreciation**Distortion is relatively small,The sound quality is better。

For example, the frequency range of the 8-inch floorstanding speaker is 40-20000 Hz, 40 Hz is subwoofer, and the subwoofer parameter is a wideband speaker, which is the best to enjoy.

The system is to take into account the bass and the middle and high tones are relatively rich--- the subwoofer increases the amount of bass a lot, if you don't know how to use it, the bass is turned on too much to suppress the middle and high tones, just listen to the bass, there is no middle and high tones (the middle and high tones are eaten by the bass - audio characteristics).

Cheap speakers are not low in bass frequencies, because the speakers are small, the speakers are small (bass above 50 Hz), the bass is relatively hard, and the ears don't like it.

Only**more expensive,Bass frequencies are better,For example, Huiwei M50W,**1280 yuan,Frequency range 38-20000 Hz (better broadband sound system)。

There is actually not a lot of mid and high tones in the speaker, but too much bass can disrupt the sound balance --- the consequences of improper operation.

Listen to the audio**, the correct way to use it is: medium volume, bass can only be turned on 1 4, large volume, bass can only be 1 5, only listen in the dead of night**, turn on the volume to the minimum (the sound next door can not be heard), the bass can be turned on all, because the volume is the smallest, the bass is very small, at this time can 100% open the bass - match with the middle and high tones.

The channel is two satellite boxes, a subwoofer, plus an external power amplifier, the function is the same, but the power amplifier is independent external, easy to adjust.

The channels are two satellite boxes, two subwoofers. With one more subwoofer, the panning ratio is more accurate, which is suitable for more demanding listening occasions.

Speaker channel function: It has two independent power amplifier modules, one is a module responsible for satellite speakers for stereo, one is a module for subwoofer speakers, and the stereo module is an independent left (L) and right (R) channel power amplifier block, and the heavy bass is a slightly higher power amplifier block after the combined filtering of the left and right channels.

The channel is two satellite boxes, a subwoofer, and an external amplifier.

The channel is two satellite cabinets and two subwoofers.

I know it's not a collection.,Reply to the collection.。

1. Different frequency divisions:

Speakers: two-way frequency, which are high and low mid frequencies.

Speaker: two-way, the small speaker is mainly high-frequency, the subwoofer is mainly bass-based, and there is no separate midrange.

2. The composition is different.

Speakers: Two identical cubes on the left and right, one main speaker and one sub speaker.

Speaker: 1 independent subwoofer and 2 satellite units.

3. The difference between the vocal channels:

Speaker: Only two channels, left and right.

Speakers: On the basis of the left and right channels, there are also subwoofer channels.

The differences between speakers and speakers are as follows:

First, the composition is different.

1. A speaker is a speaker with only two channels, left and right, and a speaker combination without an accent.

2. The speaker is composed of a subwoofer (generally called a subwoofer) and a pair of full-range speakers with weak bass (generally called a satellite box).

Second, the materials are different.

1. The speaker is generally made of wooden cabinets, with medium and high-density fiber boards, and high-end products are made of solid wood boards, and even beech, oak, mahogany and even pear, sandalwood and other precious woods are made into cabinets through deep processing, so as to obtain more perfect sound quality and highlight the dignity.

2. In order to control the cost, only the center subwoofer (commonly known as the subwoofer) is made of wood, and the middle and high speakers of the main channel are made of plastic.

Third, the scope of application is different.

1. Each speaker has a tweeter and a mid-woofer unit, which is extremely expressive. Especially in the midrange.

2. The speaker is usually composed of an independent subwoofer (commonly known as the subwoofer) and two satellite units, although the bass of the speaker is very good, but the performance of the midrange is not as good as the speaker. Therefore, it is more suitable for application in movies and games.

Fourth, ** different.

1. The materials of the speaker are exquisite, and the requirements for workmanship are relatively high, so it is also more expensive.

2. The speaker center subwoofer is made of wood, and the main channel middle and high speaker is made of plastic, which is relatively cheap.

When we understand the system, we must realize that all the channels work together to build the surround sound, and the folk often call the rear speakers "surround speakers", as if the surround sound is made from a pair of speakers at the back, which is not the right name and understanding.

There is also a misunderstanding that the concept is now applied, and the so-called "speaker" has appeared

That is, two medium and high frequency left and right channels, plus a subwoofer, to form a two-channel system. 2.

1 is not a standard, let alone a scientific statement, it is a creation.

Its prototype is a patent of American Dr. Audio, called the "Middle Bass Stereo System".

or "satellite sound system". The principle of this system is that the low frequency below 120 Hz has no obvious directionality, and has little effect on the stereo sense of orientation (note that it is not large, not none), and a low frequency unit can be omitted in the middle bass method.

In a large number of cheap computer active speaker products in China, the principle of sharing the woofer is used to reduce costs. So such a so-called 2

1 speaker, the woofer in the middle is a "shared woofer", not a 5

1 Subwoofer channel in the system.

High-end speaker manufacturers, only do.
