The floorstanding fronts offer this for bi-amping. Basically one set of connections goes to the woofers internally, and the other set to the midranges and tweeters. You could drive them with separate amp channels if wanted. Most don't do this and just use the metal strap that connects both inputs together. But it's there as a feature to offer it, as other high end speakers do.
