The price on this sub has been dropping quite a bit lately; Sears.com has it for $150, and my local Best Buy has put it on clearance for $157. I'm in the market for an inexpensive sub, so this is nice to see. It looks like the smaller SA-WM20 has already been replaced. (The local Best Buy has also put the SA-WM20 on clearance for $81.) CircuitCity.com was carrying it for $100, but it's been replaced with the SA-WM200, another 8" subwoofer with an entirely new look and upgraded amplifier (75w instead of 50w) at the same price. Is there an SA-WM400 in the works?
