I am considering replacing my bookshelf (PMC DB1) speakers with tower speakers. I have the room for towers and my room size is ample, but with so much discussion about bookshelf speakers here and products like Buchardt, I'm really wondering exactly what the upside of tower speakers are. I do not play music loud and have a sub. Is tower vs bookshelf still a quality of sound issue? Are people now tending to go with bookshelves for almost all situations that do not involve loud music?
