No monitor is really going to be able to give you a "full-range" response but can be very satisfying musically nonetheless. Are you really going to put them on a bookshelf? If so, there are other considerations, such as porting configuration. Any monitor that goes very low is going to be ported, and many/most will be rear-ported - NOT what you want on a shelf. While many of these choices are capable of producing some satisfying low-end, they need to be positioned to do so. How you plan to position and support them will also influence your choices. What are you thinking?
