"Summing Up
I very much enjoyed my time with the KEF Reference 5. It may not be a more affordable, less visually idiosyncratic Blade Two—that speaker stands alone in KEF's line—but it offers its own balance of strengths: a neutral, uncolored midrange; weighty but well-defined lows; sweet, smooth highs; and superbly secure, stable soundstaging. The Reference 5s might sound too mellow in a large, overdamped space, but in my somewhat irregularly shaped room (18.5' long by 14' wide by 8' high), the immaculately finished KEFs gave me all I need for musical and sonic satisfaction.
