Buy Cheap Stereo Power Amplifiers by Rick Lee

As we all know, amplifier power is measured in watts. If not understood properly, this is commonly a confusing subject. There is a misconception that wattage is directly correlated to the loudness and the volume.

Some people even think that by making the power output than normal results to the maximum volume. But the truth is, the stereo power amplifiers have little to do when it comes to the loudness.

However, power output is relevant to the two main issues - which are the ability of the stereo power amplifiers to handle the volume peaks and the speaker efficiency.

A music lover knows that music is dynamic, It constantly changes in frequency and level. He prefers stereo power amplifiers in his car because it allows him to understand the dynamic nature of the music he´s listening to at its best.

Whether the music be performed live with instruments or in an acoustic setting, the stereo power amplifiers provide the listener with the range that he is looking for. The quiet passages and the loud crescendos are clear.

There are also the in-between quiet moments then the loud highlights. The stereo power amplifiers accentuate the dynamic range of the music currently being listened to.

When the same music is reproduced through the cars system, the stereo power amplifiers reproduce the similar range in loudness. Whenever this is played back at the normal volume level, the medium and the soft passages of the music need minimal power.

If the receiver had 100 watts of power per channel, like what the stereo power amplifiers have, then the music would be heard better. For example, a cymbal´s clink is heard better in stereo power amplifiers.

The receiver uses only a small portion of the maximum output most of the time. This is another reason why music lovers invest in stereo power amplifiers.

Finally, speaker efficiency or the speaker sensitivity is measured by the speaker´s output that is ranged in the decibels. A specified amount of the stereo power amplifiers utilize this for the listener.

For example, the speaker efficiency is measured alongside the microphone. This is placed a meter from the speaker. When one watt of the power is delivered to the speaker and the level meter then measures the volume in decibels.

The output level then results to measure the efficiency of the stereo power amplifiers. This makes for good listening which is the main purpose of the music lover for upgrading his car´s amplifiers in the first place.
