Newegg offers the Definitive Technology Bipolar Floorstanding Speaker, model no. BP8B, for $199.99 with free shipping. That's $299 off list price and the lowest total price we could find, although we saw it for $20 less last summer. It features two 5.25" bass/mid drivers and two 1" dome tweeters with 91dB sensitivity and 22Hz to 30kHz frequency response.
