Adorama offers a pair of Klipsch R-26PF 260-watt Powered Floorstanding Bluetooth Speakers for $499.99 with free shipping. That's tied with our mention from two weeks ago and the lowest price we could find by $99, although most sellers charge double this price. They feature a 38Hz to 20KHz frequency response, dual 6.5" woofers, and a remote control.
