Harman Kardon offers the refurbished Harman Kardon Aura Bluetooth Speaker in Black for $129.99 with free shipping. That's tied with our November mention as the lowest price we've seen. (It's $29 less than we found for a new model.) This omni-directional system features a 50Hz to 20kHz frequency response, six 1.5" high- and mid-range drivers, and a 4.5" subwoofer.

Note: A 1-year Harman Kardon warranty is provided.
