It refers to the frequency it produces. Generally, subs go up to 60-80Hz. Huge ones can produce infrasonic sound (below 20Hz), if the source can provide it. Woofers handle frequencies from ~40Hz to 1kHz, although they start around 80 or so if there is a sub in the system, as well. It tends to be the bigger the better with subs, as it's hard for small speakers to produce long waves, as the excursion of the cone isn't long enough. For me, the hugest sound came from the quad-12", 2000W system a friend had in the trunk of his Monte Carlo. Turned halfway up I could hear him coming from 3 blocks away. The inside rear-view mirror was useless, and it rattled loose every fastener that wasn't Loc-Tite'd into its hole. But the sound it produced was like a sustained, full-body orgasm when he broke out the g-funk.

A little generalized to clarify for others, with traditional speakers that have a woofer and a tweeter, you try and cut the woofer and the tweeters frequency range so that they meld together. Sometimes you might have your woofer go all the way up to 5-6khz. This goes for integrating a subwoofer into a system as well. Your cut off points will always vary depending on your components, room, and desired sound.

In regards to 6.5" not being adequate for subwoofers. They do just fine.
