RE: Yamaha sub-woofer SW-100

Maintained in very good condition, just exchange two new bass unit from Yamaha, so as like brand new performance!
The SW-100 use two 5" bass unit, so response much faster that the sub-woofer use
single 8" to 12" unit, perfect to use with book-shelf speaker.

Very good conditon, cheap sell at HKD850.00 only (orginal buy at 2,000)

Yamaha YST system is the best powerful bass control system than most
other brand sub-woofer.
