Fry's offers a pair of Polk Audio R150 Bookshelf Speakers for $69 with free shipping. That's a buck under our April mention and the best price we've seen this year. (It's a current low by $29.) These speakers feature a frequency response of 60Hz to 24kHz, 8 ohms impedance, 5.25" midrange woofer, and 0.75" tweeter.
