For a subwoofer that handles both exceptionally, well, look to the Definitive Technology SuperCube 4000. With an 8 active driver pushed by an efficient 1200W amp and 2 passive radiators, the bass is plentiful, but the included remote, built-in display, and numerous options let you tune this puppy to perfection.
