One would be surprised how even bass proficient speakers can become more or less anemic in particularly (bass-)problematic rooms, which hereby becomes detrimental to the overall sonic performance. A friend of mine uses a pair of S.P. Tech Revelations (on of the later iterations), not by any means a meager performer in regards to bass, but his living room has necessitated, or rather given room to a pair of Electro Voice cinema sub's (2x18" per side), and though this approach may initially seem like shooting sparrows with ship cannons the result is immensely impressive. There's really nothing like BIG bass units (15"+) in large inclosures to handle the lower frequencues.

Myself I'm also thinking of adding not only one but a pair of subs to assist my main speakers, especially in light of what is also mentioned above on what a well-integrated pair of subs can do to enhance the rest of the frequency spectrum. DIY solutions are considered as well as some pre-manufactured dittos.
Which brings me to address the OP in suggesting a pair of Earthquake's MiniMe FP10. This is relatively fast sub with subjevtively very little overhang, and moreover there's power to spare + they are relatively affordable.
