Dream come true
Someone said subwoofer is the most important in an audio set. A good subwoofer should be able to give both quality and quantity of bass. Just a quantity of bass without good quality will make you dull and fatigue after long listening. 4 criteria for a good subwoofer :
Low frequency response to cover movie audio spectrum
Sound bars subwoofers usually have low bass response at 40-50Hz, which is not enough to play a movie with bass concentrated at 35Hz. Our compact size subwoofers can play deep bass at 30Hz bass, fully covering the whole movie audio spectrum.
Flat frequency response to represent different layers of bass
Sound bar subwoofer is ported enclosure design. It uses reflection tube to amplify a single frequency loudness which will create a sharp peak on resonant point. Sharp peak repeats on multiple of resonant frequency to form a ripple.
Graph to show ported subwoofer frequency response 20-200Hz, with many harmonic form ripple
Our subwoofer is sealed enclosure design. Frequency response is flat so that you can hear many layers of bass on each frequency band.
Wide frequency response to have fast and punching bass
Punching bass means fast rising time and fast falling time. From principle of sound engineering, fast rising means sound signal has high frequency component, i.e. a fast 35Hz signal has 70Hz, 105Hz … 350Hz… component. Subwoofer needs to have wide frequency response to reproduce fast bass. Sound bar subwoofer is narrow in frequency response 45-200Hz, while our subwoofer is 4 times wider 32-500Hz.
Powerful bass & DSP equalizing
Our subwoofer is twin drivers design, 2 drivers give 2 times of power. Size is compact, power is great, surpassing a conventional single driver subwoofer.
The subwoofer is full digital design, with DSP filter for equalizing, eliminate analogue circuit noise pick up and minimize microphonic effect. Input is digital wireless, output is 2 digital Class D amplifier direct connect to driver, those design is usually used in modern high end subwoofer.
