In your circumstances, I'd spend my first $1k on a $350 bass buster and a $600 Velodyne SMS 1 sub controller (room analyzer, PEq and active x-over) which will allow you to optimize your REL for your room and acheive a smooth blend with the main speakers of your choice. IME, once you get it right below 150hz in your room (and the SMS-1 with Bass Buster is IMHO your best shot at that, particularly in a smallish room like yours), the rest is a relative piece of cake! You will have a ton of good choices at the remaining budget of $2-$4K.
Actually, many of the recommendations above sound like pretty good ideas to me. The smaller Ohm omnis (model 100 at app $2K or Micro Tall at $1K) would also work well in your space and are appropriate for your taste. However, IMHO, my 100s (paired with Velodyne subs via SMS as per my recommendation) sound best when played north of 90db. Ohm provides a money back offer with purchase so your risk is hedged.
Good Luck
