Get these Pioneer Bookshelf Speakers (model SP-BS21-LR) for $59.99 at Newegg after you send in this $30 mail-in rebate. Plus, shipping is free. We saw these for $10 less a month ago, but this is the lowest price we found by $20 and a nice price for a set of brand-name bookshelf speakers. These 6 ohm speaker have a curved cabinet construction for reducing vibration and a frequency response of 60Hz-20kHz. There is no sales tax (except in CA, NJ, TN).
