Abstract
A speaker system which comprises two speakers and a switch for selectively connecting one of the speakers to an input through a volume controller. The other of the speakers is always connected to the input, so that in response to switching action of the switch, two speakers may operate as twin-drive woofers or the former one of the speakers may operate as a passive radiator. The volume controller is used for attenuation adjustment of the twin-drive woofers and damping adjustment of the passive radiator.
