Yamaha KS-SW100 Subwoofer

I needed a subwoofer for home use to use with a Yamaha SX900 keyboard. I did not want anything fancy or expensive and this ticked all the boxes for me. The Yamaha subwoofer has added a pleasant fullness when added to the keyboard's built in speakers. It's a very basic unit but does the job perfectly. It was just too bad it came with a European mains plug that would not work in the U.K. DV247 had forgotten to include a UK adaptor which a bad oversight and meant I had to waste time phoning them up to acquire a UK adaptor to be able to use the unit.
