Cheapest posted on Ozbargain AFAIK. Seems to be only 110v though
Price drop on the Jamo 210 sub (cheapest price, check Camelx3), and stock is in. Since this is from the UK, voltage is 240V.
Same woofer as previously posted here: http://www.ozbargain.com.au/node/87342 though $50 cheaper this time.
Just bought the Yamaha HTR-6056 and Jamo S426 speakers. And found this subwoofer on Amazon to go with them. But it's temporarily out of stock. Hope they can re-stock before x'mas.
