Kefs are great speakers. They have some wicked imaging
i think you will have alot of fun with that setup
Those KEFs are considered full range, heck, even thier KEF Q1's hit the 45hz level, but you will probably want a subwoofer.
My Definitive Technologys ProSub-200 worked great with my KEF Q1s, and at $550.00 its not a wallet buster either.
