Bookshelf, On-Wall/In-Wall, In-Wall, On-Wall and In-Cabinet. I've read several 'professional' reviews and many 'amateur' reviews of the Bookshelf M22, but nothing solid on any of the others - either as stand-alone tests or as a comparison to the Bookshelves. Can anyone point me to tests like that? With so many variations some kind of comparison would be helpful.
