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.
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?
