KEF isn't a name most are familiar with in the US but should be. KEF differs from the competition in that they use a coaxial midrange/tweeter design. The advantage is mostly in coherency and imaging. The low range drivers flesh things out and blend seamlessly. Regardless, a sub is definitely recommended. They're capable of filling a large room without distorting. When they do reach their limit, the bass drivers chuff a little. They're very smooth and comparable to a pair of speakers I use with ribbon tweeters. In the world of higher end speakers, these are definitely a bargain. The fit and finish is excellent with a unique cabinet design. Two pairs of banana plugs are available for those that want to bi-amp or bi-wire. Note that the 600 price Amazon lists is for one speaker. You'll pay 1200 for a pair. If you're shopping product in this price range from B&W, Paradigm and others, KEF should be on your list.
