Roth Audio OLi1. Small, inexpensive and with good sound all around except of course deep bass. They benefit from close boundary location like a bookshelf. And yes, that review is mine, as well as this one.
Budget bookshelf speakers FOR a bookshelf...
am looking for a set (under $600) of bookshelf speakers that will actually sound good in a bookshelf. not on top, but on a shelf with a shelf of books above and below them. max of 10" wide by 14" high. i like all kinds of music, from abba to metallica, the planets to rammstein, al dimeola to joe bonamassa. used of course is just fine :)
