There are two pair of speakers currently for sale on this site that I would recommend. One is the Ridge Street Audio Sasons at about $5500. The buyer is requiring pickup only on those. The other is the Intuitive Design Summit for about $5000. That buyer will ship. Both are stand mounted monitors but play solidly down to 40 hz or slightly lower. You could get by without a sub, and many owners of both do. I have had a good audition of the Sason and own the Summits. Both are incredibly good sounding speakers. I know I've spent many hours listening to the Summits at low to mid volume and they are mesmerizing. Check the user reviews of both on this site, they pretty much sum up my opinions of both. Good luck.
