The ear of people directly listens to so one mission critical, and it wants the direct audition with people to come into contacts with, and the audition of people is the cleverest
Quick, and the tone color of complex sound is had the strongest resolving ability.Owing to the subjective feeling of sound is evaluated by human ear just
The most important standard of one sound system tonequality quality, accordingly, it is believed that the performance height of audio amplifier is to a sound system
Playing quality be to play pivotal role.
Two divided-frequency audio amplifier typically has more than two unit, voice unit and middle bass unit composition, has labyrinth type, airtight
Formula, inverted phase type etc., box house have frequency divider, frequency divider separate high pitch and middle bass respectively signal send into high pitch loudspeaker and
Medium and low spectrum loudspeaker, due to middle bass be mix in order to show woofer it is necessary to have certain amplitude thus
Can be more inferior than three-way speakers during performance middle pitch, existing two divided-frequency subwoofer speaker weak effect, noise is big.
