Coaxial acoustics are most commonly used in automobiles. It is a system that is divided into three bands of high, medium and low frequency. Additional speakers, if necessary, are placed on the same axis with the main speaker, which, as a rule, operates at low or medium audio frequencies.
Principle of operation
Coaxial acoustics is realized through a capacitor, which acts as a frequency filter, separating the sound into high-frequency and low-frequency ranges. Using a capacitor instead of other filters allows you to achieve a lower cost for such devices, while maintaining a decent sound quality. As a rule, coaxial acoustics are two-frequency, but sometimes three-frequency devices are used if there is a speaker that reproduces sound at a medium frequency.
Pros of coaxial speakers
When installing an inexpensive audio system for a car, it is better to install coaxial acoustics, since in quality it does not lose to similar standard component systems, but coaxial speakers are much lower in cost. Also, the sound quality of music can be determined by the location of the coaxial speakers and the location of the sound source in the car. In combination with component acoustics, coaxial speakers are also installed to provide sound for the rear seat passengers.
Such speakers are installed in the doors and on the rear shelf of the car trunk.
Another advantage of coaxial acoustics is its ease of installation. Component systems require adherence to a number of rules during installation, since each of the sound sources is self-contained and must be placed in accordance with special rules and using acoustic zones. Most often, it is required to make special shelves for speakers and create additional noise isolation, as well as purchase additional equipment to amplify sound. Coaxial speakers do not require a reinforced radio, which can also be quite expensive. Connecting a strong component audio system to a weak radio tape recorder will be useless and will not give the desired improvement in sound quality.
Coaxial acoustics are often used in small cars as well.
Cons of coaxial systems
Among the disadvantages of coaxial systems is their relatively low sound quality compared to full-fledged component systems. This is due to the fact that the sound of different frequencies comes from the same speaker - in the process of sounding the frequencies are mixed, which has a negative effect on the sound. This distortion is not observed in a component system, since it uses several speakers of different frequencies, which are connected to different channels of the amplifier or radio.
