When installing serious audio equipment, there are many parameters to be observed. In particular, the power of the speakers should not exceed the power of the amplifier. At the same time, in order to get the maximum effect from the acoustics, it is important to accurately calculate the power of the speakers so that it is not much lower than the corresponding parameter of the amplifier.
Instructions
Step 1
First, decide on the power parameter, the lack of which affects the volume and the dynamics of playback. The output power of the amplifier cannot be more than the power of the entire acoustics. Otherwise, the amplifier may damage the speakers. For example, for a room of 20 square meters, 80W acoustics are enough, and for a room with a total area of 40m2, a power of 150W is suitable.
Step 2
Pay attention to the sensitivity of the equipment. The higher it is, the better, because in this case you do not have to select a very powerful amplifier.
Step 3
Determine the frequency range within which the speakers are capable of reproducing audio. Acoustics should reproduce the entire sound range (from 2 to 40,000 Hz). Although, if a subwoofer is installed in the system, then some low frequencies can be neglected.
Step 4
Also look at the speaker type. If the speakers are active, then each frequency is additionally processed by a separate amplifier. As a result, the speakers are connected directly to the amplifiers, which improves sound quality and gives a wider range of reproduction. A passive system requires the mandatory installation of an external amplifier, but does not need to connect a line signal to each speaker separately, which is necessary in active acoustics.
Step 5
An important parameter is the type of housing. The most commonly used design with a bass reflex. The transient characteristics of acoustics are well improved by a closed-type housing, but degrades the transmission of low frequencies.
