Obviously, you don't want a speaker that has a rear port.
Two speakers whose manufacturers' web sites show them on shelves are the Thiel SCS3 and the Wilson Duette. I haven't heard either of them, sorry, but both manufacturers have good reputations (if slightly controversial in Wilson's case). I would urge you to consider auditioning them yourself. Good luck.
