The dual voice coil which carried out the winding wire of the coil according to right-and-left channel to the voice coil bobbin of the Woofer is adopted.
It is possible to reproduce the low-pitched sound region of the channel of both of right and left by 301 DS-W by this.

The low cut ON-OFF switch of a main speaker is carried.
