Speakers come in tweeters to handle the treble notes and woofers to handle the bass notes. Subwoofers are those speakers that these youngsters put in the trunk of their car so that they shake the whole street as they drive past.
Sub is short for submarines, an underwater boat.
A submarine is a watercraft capable of independent operation underwater.
From your neck of the woods:
The submarine became a potentially viable weapon with the development of the Whitehead torpedo, the first practical self-propelled or 'locomotive' torpedo. The spar torpedo that had been developed earlier by the Confederate navy was considered to be impracticable, as it was believed to have sunk both its intended target, and probably the H. L. Hunley, the submarine that deployed it.
