Canton's SUB 12 is an active front-firing subwoofer. Able to handle up to 350 watts, each enclosure houses a 10-inch aluminum wave surround woofer. The SUB 10 features Canton's SC technology, which uses individual filter switches to extend the subwoofer's transmission range by an octave or more, with a consistent, clear sound. The SUB 12 conforms with Europe's green standard and consumes less than one watt of power in standby mode.
