If you already have an acoustic system in a car, then for complete happiness you lack only a subwoofer. But in order to purchase it, you need to get acquainted with its classifications for a start.
First of all, let’s figure out what a subwoofer is. The subwoofer is an inseparable part of the sound system. It allows you to reproduce low sound frequencies. A person, thanks to her, can hear a sound with a frequency of 20 to 200 Hz.
The subwoofers are classified according to different parameters. For example, hull and freer. Corps subwoofers have a case (box). They are also divided into three most common types: closed, phase -inverter and bypass. Closed are a closed box with a speaker and there are no holes in them. In the phase -inverter subwoofers there is a port for air movement. In the bypass buildings, the speaker is inside the box. To choose one of the three types of subwoofers, you must first decide what kind of music you prefer to listen. If this is classic or instrumental music, then a closed subwoofer is suitable for you, since it is able to most clearly transmit low -frequency components of sound. For lovers of club and rock music, where the volume is most important, a phase-inverter subwoofer is suitable, since it has a power ratio and sound pressure is much higher than that of a closed body. Well, bypass are suitable for those who are more interested in the beauty of the system than in the sound. The corps of the subwoofer can be made transparent (glass), install the backlight in it and much more.
But the peculiarity of the Freeric subwoofer is that it is designed for work in free space. For him, the main thing is to separate the back of the subwoofer from the front. Installed in the rear shelf of the car, mainly in a body type sedan. With all other types of bodies, the installation is more complicated. Suitable for those who like to listen to classical and instrumental music.
Also, subwoofers are divided into active and passive. Active has a built -in amplifier, and, as a rule, this is a factory design design. It provides ease of installation and convenience of setting. Used in entry -level systems. In a passive subwoofer, the sound signal is supplied from an external amplifier, which allows you to improve the system, and as a result, complicates the installation. That is why it is used in advanced level systems.
One more classification of subwoofers can be distinguished – by the size of the speakers: 8, 10, 12 and 15 inches. The most common of them are 12 inch, as they more accurately meet the requirements for the price, compactness and reproduced sound pressure. 15 inch subwoofers have a big plus-this is power, and there is also a big minus-it requires a very large volume in the car.
So, we found out that lovers of acoustic and instrumental music should give preference to closed buildings of 10, 12 inches, and lovers of club and rock music-phase-inverter buildings of 12, 15 inches. Those who have chosen Freeric subwoofers can limit themselves to 10 inches.
After you have decided on the selection of a subwoofer, you must also prepare for its installation. First of all, it is necessary to do vibration isolation of the body, otherwise the result after installing the subwoofer may not be provided as you expect. Success!
