I can't comment on the Wharfedales, as I haven't heard them, but in my 17x17 room, (sort of, as there is an adjoining alcove & another hallway) I have Axiom M22ti fronts, VP150 center, and a SVS PC Ultra sub. Couldn't be happier. I'm amazed at the Axioms when I turn the sub off. Reasonable bass extension, and just really nice midrange and clear highs. The sub will rock the house with movie and game explosions, etc., yet when playing music is it absolutely not localizeable. I have never had a subwoofer that blends as well. Like so many things now in our time of advanced technology, you have several excellent choices for all of the components and probably will be happy with any of them.
