The main points of sound audition
This section is dedicated to hearing if part of the human voice is contaminated by the speaker tones, which is an easy flaw in general speakers.
Low frequency/medium and low frequency disorders:
It is easier to hear that the usual sign is a sound buzzing or a floated sound.
The fullness of the low-frequency:
Whether the sound of a stringed instrument is abnormally sharp or dry or excessively sweet. Also listen to a few more discs to ensure that the poor sound quality is not caused by the record itself.
High frequency clear:
In most music there is little more than 13,000 khz, and if you do hear the sound of this frequency, it is only a flash, not a musical sound. Listen to each of these instant treble to see if it's dark, too sharp, and vague.
In short, the good speaker of the test should be: High frequency slender compliant, if full and bright, low frequency solid clean rich elasticity and a sense of full.
