Are there any advantages to floorstanding speakers over bookshelf ones?
Floorstanding speakers thanks to their size can produce more volume and therefore move more air which in turn will produce a bigger sound and undoubtedly better bass. There are of course exceptions to the rule where a bookshelf speaker can produce stunning sound such as the PMC DB1. But do remember that by the time you put the speakers on a set of speaker stands they take up about the same amount of room.
