Watch your favorite movie or listen to music is always nicer with high-quality sound. How to choose an audio system for your needs and preferences and not to overpay if there are a huge amount of them on the market? In the article we will talk about the main characteristics that need attention.
Purpose
First and foremost, determine what you plan to acquire it for:
- personal computer;
- home theater systems;
- music player.
Estimate the volume of the room where it will be installed. From these two factors will depend on the required power, size, and, accordingly, the budget.
System selection
Under the range of reproduced frequencies, speakers are divided into the number of bands. If you are not a music lover, you do not have special quality requirements, then a single-band system will do for you - one speaker works for all sounds. This is the easiest, budget option. But the most common - two and three-way. In the first case on one speaker there will be one medium and low frequencies, on the second high. In the three-band - each band has its own speaker. The more bands the system has, the better the sound quality.
Power
Immediately determine - the volume and power - two completely different parameters. In fact, power - determines the mechanical reliability of the system. Above this figure - columns will last longer.
IMPORTANT: When choosing a speaker system, make sure that the power of the speakers and the amplifier is equal. The speakers will soon fail if the power of the amplifier is greater.
Sensitivity, frequency range
Sensitivity is the parameter that really determines the volume. It is measured in dB and shows how strongly the sound affects the surrounding space. Higher sensitivity - louder, more powerful sound is obtained. It is measured at a distance of a meter from the speaker with a 1 kHz sound supply, 1 W power.
The device of a human ear distinguishes a sound signal in the range of 20 Hz - 20 kHz. At the same time, low frequencies are in the range of 20-150 Hz, medium - 100-7 kHz, high - 5 kHz-20 kHz. If you are looking for home theater acoustics, then there are enough frequencies in the range of 100-20 kHz. For universal use is worth the attention acoustics with an extended range - 20-35 kHz.
Important: After 30 years, a person perceives frequencies that are higher than 16 kHz, below 30 Hz.
How the output level depends on the frequency change, shows the amplitude-frequency characteristic (AFC). The ideal form of graphics - direct, passing at the level of nominal power. But in practice this does not happen. The closer the frequency response to the straight line, the better. Any sharp jumps show that the acoustics distort the sound
The material from which the speakers are made affects the sound quality. It can be plastic, wood, chipboard. Each material has its own advantages and disadvantages. For example, plastic is a cheap, lightweight material. Even speakers with an unusual design, distort the sound at high volume. Usually, they are connected to a computer.
Their cost is one of the lowest. If you plan to listen to music, it is better to do this through acoustics with a wooden or body of chipboard. It will be a good option. Such speakers do not rattle, they have almost no distortion of sound, they provide decent sound quality. But this should not be the main argument for the purchase.
Now you know that when choosing a speaker system you cannot limit yourself solely to price, exterior design and color. We hope that this article will help you choose an option for your requests and dismiss unnecessary options.
