Best Buy has the Polk Audio - 6-1/2" Coaxial Loudspeakers with Poly-Mica Cones (Pair) for $29.99 (shipped free), $70 off the regular price. A great steal if you're needing some nicely-rated loudspeakers.

From Best Buy: "These loudspeakers feature poly-mica composite woofer cones that are stiff, yet lightweight for big sound and minimal distortion. The swivel-mount soft dome tweeter allows for precise aiming of sound. "
