They're not about deeper bass.
Most people add a subwoofer to get more bass or extend their speakers' low-frequency range. But that's backwards. The real reason to use subwoofers in a high-quality system is to decouple bass reproduction from speaker placement. Your main speakers need to go where they image best. Your subwoofers need to go where the room's bass response is smoothest. These are almost never the same location.
Think about it—you've spent hours positioning your speakers for perfect imaging, depth, and soundstage. They're probably four or five feet from the front wall, precisely toed-in, positioned to create that magical disappearing act. But this placement, optimized for imaging, might put the speakers in a bass null where certain low frequencies simply cancel out. Or it might excite room modes that make the bass boomy and uneven.
Subwoofers let you solve both problems independently. Set up your main speakers for the best possible midrange, treble, and imaging. Then place your subwoofers where they interact best with the room's bass modes—often in corners or along walls, anywhere but where your main speakers sit. Run your mains full-range and use the subs to fill in what the room is taking away.
I've seen this transformation countless times. The system suddenly sounds more coherent, not because there's more bass, but because the bass is finally even and natural across all frequencies. The deep notes that were missing appear. The boomy notes that were excessive smooth out.
Subwoofers are room correction devices that happen to make sound.*
