Im fairly new to the HT scene, but am learning a lot. Im thinking about buying some Wharfedale Monitor speakers, except for the fact that I dont know what the "Monitor" in Wharfedale Monitors means. It seems to be categorized in a "bookshelf" category. Am I wrong? I know theyre floorstanding. Do these make good mains? Not the Wharfedaled specifically, but monitors in general. Could someone explain the difference?
