Acoustic Sound Design via Amazon offers the Bic Acoustech Platinum Series 12" 250-watt Powered Subwoofer in Black for $249 with free shipping. That's tied with our mention from last September and the lowest price we could find by $80. It features a 250-watt RMS continuous output (1,000 watts peak), 12" long-throw woofer, and 22Hz to 200Hz frequency response.
