Sound Investment
TAD’s new loudspeaker will blow your mind (and eardrums, perhaps)—for $150k less than the brand’s flagship model.
As with certain elite brands from watches to wine, Technical Audio Devices (TAD) is coveted by the cognoscenti while remaining off the radar for the mass-market audience. Launched in 1975 by Tokyo-based Pioneer Corporation to develop loudspeakers for professional use, the Japanese boutique manufacturer spun off in 2007, guided by the ethos “artistic intent, intact”. When its magisterial Reference One was subsequently adopted by recording studios and engineers obsessed with the most accurate reproduction, the audiophile community took note.
At around $255,000 per pair, TAD’s top loudspeaker, the Reference One TX, is among the finest available at any price. But the more recent Evolution Series shares the same DNA while incorporating new materials and manufacturing techniques that make the atelier’s elevated audio reproduction available at an easier investment. Case in point: the new Grand Evolution One (GE1), priced at around $103,000 for the two.
We recently listened to TAD’s GE1 alongside its six-figure flagship and found a remarkably similar sound signature between the two—proof that trickle-down technology is alive and well. Just like its costlier counterpart, the GE1 is about precision, built by hand to micron tolerances in laboratory-like conditions; standing more than 1.2 m tall and weighing 64 kg, its three-way design uses a bass-reflex enclosure with two 18 cm cone woofers and a Coherent Source Transducer (CST) combining a midrange and a tweeter. The heart and soul of every TAD loudspeaker, the CST is the primary reason for the level of sound parity between the disparately priced models. Its 14 cm magnesium cone crosses over at 1.8 kHz to a 3.5 cm beryllium dome, which is produced using a complicated vapour deposition technique.
The incredible coherency and speed come courtesy of the transducers’ concentric configuration, which allows frequencies from 250 Hz to 100 kHz (well beyond audibility) to be delivered from a single-point source. The result isa holographic sonic image without the diffraction and phase anomalies that occur when multiple transducers are arrayed across a front baffle. As for the woofers, each one uses TAD’s custom aramid fibre diaphragm and goes down to 27 Hz. These speakers are easygoing about room placement and, at 88 dB, are moderately sensitive. They present a four-ohm load, meaning a powerful, solid-state amplifier is an ideal match.
While there’s a lot of competition in the $80,000 to $110,000 range, the Grand Evolution One is for critical listeners who want to hear every acoustic nuance without the fatigue that often accompanies the etched and overanalytical detail found in some of the most popular top-end speakers. But the GE1 isn’t warm, romantic or rose-coloured, either—TAD developed its CST transducer to keep the music “intact”, after all, and that accurate, engrossing sonic signature is the embodiment of authenticity.
