What sound quality is good to see how much output power is

What is the sound quality is good? This is what we often ask the question, in fact, what sound beats by dr dre quality sound a good sound on the sound, but many times the key sound quality is a good factor with the output power has a great relationship. There is no direct relationship between sound quality and power. Power is determined by the speaker can issue the maximum sound intensity, the feeling is the sound of the speaker can have much of the shock. According to international standards, power has two labeling methods: rated power and instantaneous peak power. The former is within the rated range to drive an 8 speaker to specify the waveform continuous analog signal, after a certain interval and repeat a certain number of times, the speaker does not produce any damage to the maximum power; the latter refers to the speaker can withstand a short time the maximum power The The United States Federal Trade Commission in 1974, the provisions of the power calibration standard: two-channel drive Beats By Dre Sale an 8 speaker load, 20 ~ 20000Hz range of harmonic distortion is less than 1% measured when the effective wattage, that is, the amplifier Output power, the marked power is the rated output power.

The power of the speaker is mainly determined by the power of the power amplifier chip and the power of the power transformer. Considering some other factors, it can be calculated that if the rated power of the transformer is 100W, beats by dre studio it can actually drive the power of the amplifier chip below 45W , So by the sound box transformer and power amplifier power relationship can also verify the actual rated power of the speaker can reach the nominal value. The power of the speaker is not the bigger the better, the application is the best, for ordinary home users about 20 square meters of the room, the true sense of the 60W power is enough, but the power amplifier reserve the greater the better, The actual output power of more than beats earphones 2 times. Such as the speaker output is 30W, the power amplifier is better than 60W, for the HiFi system, drive the amplifier power amplifier is very large.
