@Mcanaday According to my Radio Shack SPL meter and a Stereophile test CD, I'm about -2db down at 63hz with the Silverline Minuets which incidentally measure flatter (at the listening chair) overall than both the Harbeth P3ESR and Kef LS50 in the same room which both have slight boosts in the upper bass range.
Depending on your music and bass requirements, it'd be hard to say whether or not you would want a subwoofer. In a room your size, and with most of the music I listen to, I'd be fine with the Minuets sans subwoofer.
As I've said in other posts, the Minuet is a small speaker and while it certainly can sound bigger than its size, both the (higher priced) Harbeth and Kef as well as an Omega Super 3XRS single driver speaker I use all sound larger and than the Minuet and compose themselves better in my room (just a little larger than yours) when the music gets complicated.
