Commentary
A woofer system developed for low-frequency enhancement in small speakers.
A 30 cm cone type woofer is installed in the low range.
The voice coil of this unit uses a dual voice coil system, and by winding separate coils for the left and right channels on the voice coil bobbin, it is possible to reproduce the low range of both the left and right channels with one unit.
The main speaker has a low-cut ON/OFF switch that allows you to switch between low frequencies and low frequencies according to your preference for efficiency and sound quality.
You can switch between the 3D method, which reproduces the low range of both left and right channels, and the normal stereo method, which uses one DS-W30 for each channel.
The enclosure is sealed and designed to have a minimum resonance frequency of approximately 30 Hz.
In addition, the internal structure is a dispersion resonance type, and by dispersing the resonance mode, box sound is suppressed and low sound reproduction capability is improved.
