Many audio whites like to look at the frequency response when buying speakers, and think that the lower the number means the better the low frequency (bass), especially some 6.5-inch two-way bookshelf boxes, the low frequency response can be nominal to 35Hz, do you believe it? What is the truth?
Suppose there are four pairs of 6.5-inch mid-bass two-way bookshelf speakers, the frequency response is 35Hz-25KHz, 32Hz-25kHz (-15dB), 35Hz-25KHz (-10dB), 56Hz-25kHz (±3dB), judging only from the parameters, which pair will you choose?
Many small bookshelf boxes look at the frequency response is very scary, 6.5-inch mid-bass two-way can reach 35Hz-25KHz, understand a little parameter of a look, yo, awesome, low frequency dive so deep! In fact, this is a trap, the business deliberately does not standard the frequency characteristic parameter decibel value behind the frequency response, because it is very unideal, when the low frequency down to 35Hz, the sound pressure is likely to have been greatly attenuated -10dB or even -15dB, which means that the low frequency at this moment has been faintly basically inaudible, is meaningless. 35-25KHz remove the reference decibel value behind, to put it bluntly, that is a lie. In fact, the three parameter values of 35Hz-25KHz, 32Hz-25kHz (-15dB), 35Hz-25KHz (-10dB) are basically the same speaker or similar standards. The decibel value ±3dB after the frequency response is the minimum standard for HIFI, and the lower the value, the flatter the frequency response curve and the lower the distortion. Completely unlabeled, that kind of data is worthless, it is completely deceptive.
The above is the data of the ATC100 professional studio active box, 12-inch bass three-way frequency, frequency response curve 65Hz-17kHz (±2dB), which is the standard of professional monitoring, but also the standard of hiend, and even more bullish is ±1dB. Why does the 12-inch bass dive only to 65Hz, because of this frequency band, its sound pressure has almost no attenuation, if a pair of small boxes can be marked to 30 hertz, because the sound pressure has been attenuated to almost inaudible, it is meaningless, this is actually deceiving people.
It is the reason why those so-called small bookshelf boxes have innate divine power. [White Eyes]
Let's take a look at whether the frequency response labels of some brand speakers on a certain treasure are standardized:
1. The picture above is the advertising picture of Payon 4 speaker, the frequency is not marked "±dB", which is not standardized enough, but its low frequency is 50Hz should not be too exaggerated.
2. The picture above is the advertising data of the Dynaudio BM series, you can see the frequency response specification of the frequency signal, and the larger the speaker size, the smaller the response number of low-frequency diving, which is really an inch bigger and one inch stronger.
3. The picture above is the advertising data of Zenith active speakers, marking specifications, and it is also an inch larger and an inch strong low-frequency dive.
4. The picture above is the advertising indication of our domestic wind sound box, which is also very standardized and worthy of praise (Wind Voice No. 2 is very good to eat, push well to fully play its low frequency, indeed overwhelming, I personally test, not advertising ha, pure science).
Of course, the data is only a reference, whether the real sound (low frequency) meets your needs, in addition to the quality of the speaker and the speaker itself, it also depends on the matching of your sound source, power amplifier, cable and even power supply; Everything should be based on your listening sensation, try to listen to it live, and choose the sound you are most satisfied with within a limited budget, after all, there are a thousand Hamlets in a thousand listeners, and your sound is your choice [croak]
