The subwoofer adopts a Dynamic Bass System in which port, duct and air
cavity (A) compose an acoustic bandpass filter in front of air cavity (B).
By virtue of this structure, the bass reproduction limit is extended and sounds
higher than middle range frequencies are reduced. This makes it possible
for the unit to reproduce powerful bass sound.
