Save a little cash -- a couple thousand. Zu Druid V meets all your requirements, including real, articulate bass down to 35Hz. Perfect for your size room and the relatively near field listening layout. I migrated to Zu from Silverline eight years ago. You'll have a smooth transition, at once in-the-realm and clearly an advancement over the conventional crossover-intensive speaker. Druid V is all you need and leaves some money for more music.
