Whereas most dynamic speakers struggle to integrate their driver outputs into a semicoherent blend in the far field, the 107 is seamless. What struck me immediately about the 107s, when I heard them first under show conditions, was their wonderfully cohesive and effortless sound. That impression has not diminished in the comfort of my own home. The transition from the bass to the mids is magically integrated, and the conviction with which I perceive instrumental space and focus across the soundstage is heightened considerably.
Music emerges from the 107 like ripples in a clear mountain lake. There is no sense of strain or stress, even on very loud passages. The vocal-range magic of the Spendor BC1 and SP1 is present here in full force. Voice is reproduced very naturally, without any coloration. Neither are instrumental timbres slighted in any way, and harmonic accuracy is preserved up and down the audio bandwidth. String fundamentals and overtones are convincingly reproduced, and woodwinds possess excellent clarity and detail, while brass has its proper bite, without gratuitous brightness or harshness. With the right electronics, musical textures are fleshed out with a convincing mixture of soft and hard, sweet and brash. ...
There are two other prize-winning aspects to the 107. First, the bass. The quality and quantity of the bass octaves are exceptional—the best I've heard from a conventional full-range system. Bass power, impact, and clarity leave one breathless on orchestral spectaculars. Second, headroom is sufficient to duplicate, at a typical listening position (even in a large room), the full dynamic range of any orchestral work—even a Respighi. The 107 gracefully complies with the dynamic demands of the music—it's capable of blooming from soft to very loud without a trace of compression or distortion.
