Need some help choosing speakers.......

I hope some of you experienced audiophiles can help me with a choice of speakers. I intend to move my electronics from ourt summer mountain house, which we winterize, downto a Florida condo for the winter. My B & W 804's are too large for the condo, so I would like a pair of monitors perhaps, which do not have to be placed far from the back wall. Even better would be a pair that would work in a very heavy, 2" MDF bookcase system. Electronics are: Audible Illusions L-1 pre-amp, Pass Aleph 3 power amp, Magnum Etude fm, Sony SACD player. Speaker sensitivity should be about 89 db or higher. Thanks for your input.
