Ultra one system is a three frequency division technology, which converts the built-in frequency divider of the traditional speaker into the digital frequency division output of the DSP power amplifier, so as to accurately restore the sound. Three speakers are used alone to perform their respective functions, representing bass, mid bass and treble respectively. The sound is perfectly restored and truly reaches the hifi level.

The bass adopts the reverse airflow loading design technology, which shows amazing elasticity and diving fullness, low-frequency compactness, authenticity, and fast recovery speed. A single mid bass speaker unit can better restore the whole vocal basic frequency band (100hz-3kz), which makes the singing feeling of singers very easy, smooth and smooth, and has good phase consistency. 

The active phase correction technology is adopted, which is a realm that can not be reached by traditional two frequency audio.
