One should listen to Bose Companion 20. It is as good as a 2.1 system. ( That is why I asked the OP to give it a hearing.)
".......the Companion 20 has knocked our socks off. The sheer volume and drive produced by these 2.0 speakers is astonishing and bass, if anything, is fractionally more prominent than it would be in a typical 2.1 arrangement."
