Polk Takes New Approach to Surround Channels

The Polk FX Wireless Surround ($399) assigns surround-channel duty to a single speaker that sits on the floor behind the sofa. We heard it and it worked, though it worked better when we weren't standing over it with a camera. If surround aversion is a disease, this may be the cure, and quite an audacious one. Please note that the foot isn't ours. We wear Hush Puppies.
