The first thing you notice about the Reference One is its rounded, graceful shapes. The direct descendent of the Model One, this new loudspeaker is based on the same fundamental principles of a stiff cabinet along with a concentric beryllium midrange/tweeter. This background brings us to the subject of this review, the TAD Reference One. When Jones did a patent search while researching prior art in preparation for filing his own patent application for a concentric driver, guess who owned the late-1970s patents on concentric technology? That’s right-Pioneer and TAD. But TAD was no stranger to concentric designs. Jones had long worked with concentric drivers, specifically KEF’s Uni-Q concept. One advantage is perfect coherence between the drivers no matter what the listening position in relation to the loudspeaker. In a concentric driver, a tweeter is mounted at the center of the midrange cone. Many of the best loudspeaker companies design stiff cabinets, but a concentric midrange/tweeter driver is quite rare. The Model One was notable not only for its heroic enclosure, but for its concentric midrange/tweeter, both made from beryllium. Cordesman bought a pair), but the enclosure turned out to be just too difficult and expensive to manufacture. The Model One was a sonic success (our Anthony H. This construction was revived a few years later by Magico in the Mini, scaled down in size by an order of magnitude. Jones’ first product for TAD was the Model One, an audacious ground-up design whose massive cabinet was built from horizontally stacked birch ply. They hired the talented loudspeaker designer Andrew Jones, who had spent much of his career at KEF working with legends of British loudspeaker design including Raymond Cooke, Laurie Fincham, and Peter Baxandal. In 2000, TAD decided to create a division that would bring to the consumer market some of the technologies the company had developed for the professional audio world. In fact, the techniques they employ today remain unique. But 35 years before this renaissance in beryllium, TAD developed proprietary processes for working this notoriously difficult metal into the specialized shapes of loudspeaker cones and domes. Rockport, Magico, and Focal are among the ultra-high-end loudspeaker companies now using beryllium tweeters. It is extremely light and stiff, making it the ideal material for driver diaphragms. Beryllium is the hot buzzword today-and for good reason. One of the innovations that arose from this development effort was driver diaphragms made from beryllium. This division’s very name speaks volumes about their charter no flowery language or marketing spin, just the words “technical,” “audio,” and “devices.” The combination of solid funding, contributions from some of audio’s brightest thinkers, and a mandate to create products that broke new ground resulted in several patents, Audio Engineering Society papers, and some remarkable inventions. This division, called Technical Audio Devices (TAD), operated much like a completely independent research laboratory. Most audiophiles don’t know this, but in 1975 Pioneer Electronics created a kind of “skunk works” to develop highly advanced, cutting-edge loudspeaker technologies for the professional audio market.
