Two-way and three-way car speakers: A fundamental choice

What type of speakers to choose in a car - two-way with a low purchase price and very high-quality sound in the cramped conditions of the car interior, or three-way speakers “with full coverage of acoustic frequencies” offered by many acoustic manufacturers from China today? Such a choice today is becoming very relevant and in demand for car owners who already have cars and are planning to soon acquire a comfortable means of transportation on modern city streets and suburban highways.

Let’s try to systematize the scattered and scattered information on the Internet in this small information and reference material, which will help motorists quickly and profitably solve the issue of installing car audio in a car - choose the car speakers ideologically correct and relevant to personalized requests, covering all the interests of a particular owner a / m of sound frequencies. And, importantly, without loss of quality and meetings with frankly fraudulent offers preferring to deceive buyers of unscrupulous sellers and manufacturers of acoustic devices.

Acoustic "strip"

What is the "lane" dynamics in the human language? The number of acoustic bands in a column means the number of independent sound speakers mounted in one enclosure. If it’s simpler, this is the number of “mini-speakers” inside one large speaker, designed to reproduce “their” frequency spectrum.

In a two-way column 2 speakers. In a three-way column there are 3. It is almost impossible to make a mistake.

Why column "strip"

The answer to this question is in the technical plane. The number of speakers mounted in one enclosure, characterized by the "band" of the acoustics, corresponds to the spectrum of frequencies reproduced when listening to music.

Two-way speakers have separate bands for playing sounds of different frequencies, as are three-way speakers. The need for such a separation is due to the peculiarities of human hearing - a person is able to perceive sounds from many sources at the same time, "isolating" individual instruments and vocals (voice playback) from different people from the general acoustic picture. The “universal” speakers in single-band systems cannot physically divide sound in different frequency ranges - a single membrane is forced to emulate different frequencies with a constant loss in the quality of perception of sound “information”.

It is precisely for the qualitative "division" of reproduced sound tracks with automatic division into frequencies of the corresponding ranges that the independent speakers in the "multiband" speakers are responsible for.

Two-way speakers

The most popular two-way speakers on the market today have separate channels for reproducing the following frequencies:

  • MF and LF;
  • HF.

In rare cases, a two-way speaker is not able to reproduce low frequencies, which negatively affects the capabilities of the sound system - some music genres cease to sound in accordance with the idea of ​​the authors of the work. In such cases, you have to think about installing a separate sound reproducing device for low and ultra-low frequencies, called the “subwoofer”. For this reason, motorists who are not well versed in acoustics recommend looking in the direction of more “strip” speakers, which will be discussed below. Here's where you can find more info: 2 way vs 3 way speakers

Three-speaker acoustics

The three-way speakers possessing three “bands” favorably differ from the two-way “brothers” in a more clear and explicit division of frequencies into:

  • LF;
  • midrange;
  • HF.

That is, in a three-way system it will be possible to distinguish sounds in each frequency range due to their better and more explicit division. Each "mini-speaker" in such a device is responsible for its "own" frequency, providing the best sound quality of the desired frequency range due to:

  • mathematically selected membrane size;
  • component base for the desired frequency;
  • resonator size.

On the one hand, the advantages acquired by the owner of such a sound system are obvious - separate sounding of frequencies with a pronounced acoustic picture, however, this separation has a significant drawback that applies only to car audio.
