Smallest Bookshelf Speaker Worth Listening To


Does anyone have any opinions on the smallest bookshelf speaker worth listening to> I found the Kans to be quite good in a bookshelf system, but wonder if there are others that are even smaller in size. I remember some years back being taken by the small size of the Acarian Alon Petites and they sounded great in a full blown setup. So what is out there today?

Unbelievable speaker. Great image and powerful bass with good Class A SS. In a small room they simply sound huge and transparent. Not bad to look at,either.
I own both the ProAc Tablette 50 Signatures and Response 1SCs and think they're magnificent. Much more refined and bigger sound than I thought possible from such little boxes. I usually run them with a sub, but often turn it off to enjoy the purity of these monitors.
