Yamaha YST-SW90 Passive Subwoofer +

Like new, no marks. scratches, tears, used to give my 7.1 surround sound system a decent bass, can be used with any amplifier, probably best subwoofer around for the money, here is the specs... Product Information The Yamaha subwoofer is a floor-standing amplifier/speaker system that is a great complement to a home-theatre system with its 100 watts of peak power. The Yamaha YST-SW90 is a one-way and magnetically shielded subwoofer that responds to frequencies anywhere between 50 Hz and 150 Hz. This 100-watt subwoofer provides powerful bass for both music and video, which gives the user an enhanced listening and viewing experience. This effect is possible thanks to the presence of a 20.32-cm (eight-inch) spruce cone driver in the Yamaha subwoofer. With the Yamaha YST-SW90 it is easy to match the output from the subwoofer and the other speakers in the system for a seamless sound effect. The volume can be adjusted on the 100-watt subwoofer so as to match the volume coming from the rest of the speaker system. The convenient signal-sensing capability of the Yamaha subwoofer enables it to switch itself on if it detects a signal, or alternately to switch itself off if after several minutes there is no incoming signal.
