I am brand new to anything to deal with speakers so I apologize if this sounds infantile or redundant. I am looking to upgrade my old kenwood bookshelf speakers right now. I have read that it won't it is plausible to send my bookshelves I use as fronts right now, to the rears and they will work fine....is this true? Now, I am not sure if I should get floorstanding for my new fronts or stick with bookshelves. I have a good bass so the bass is not important so is it worth the extra to get the floorstandings? I saw the deals on the Polk R40's earlier but unfortunately I don't have a Fry's around here. I am also looking at the Home Theater Direct Level Three towers and Center. Are these a good buy at about $600 for them all or is there better speakers to be had out there. Thanks for any help or speaker recs.
