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?

There a quite a few companies that make smaller bookshelf speakers. Off the top of my head:

Pro Ac Tablet
Paradigm Mini Monitor
Linn Tukan
Dynaduio (I forget which model)
B&W DM303

Just to name a few.
After listening to numerous small monitors I can say with confidence that the the ProAc 1SC is in indeed world class....especially w/ tubes particularly Audio Research.
The Realistic Minimus 7 is smaller than all of the above and sounds angelic driven by a Krell FPB-600. You just have to get speaker cables that have pins on the speaker ends.
New B&W DM600 series 3. About $300-$350. They can be mounted to a wall.

I really like the Samadhi Acoustics Magic Cube, designed by Dick Olsher with WAF consulting provided by Lesley. The Cube is 7.75" on a side, and it is worth listening to. Whether it's the smallest speaker "worth listening to", I dunno. I don't sell it, but I do recommend it.
