Düsseldorf (Germany), June 28, 2019 – Originating from the uncompromising craftsmanship of Technical Audio Devices Laboratories, Inc., we are proud to introduce a new generation of Reference Series Speaker Systems.

Building on the TAD-R1 and the TAD-R1MK2, which have received excellent ratings on the audiophile market as flagship models of the Reference Series since their original release, we are launching the pinnacle of floor speaker systems, the new TAD-R1TX, as the next generation. We have pursued sound quality to its utmost limits by pooling the skills of technical experts”, says Jürgen Timm, Marketing Director Europe of TAD.

Following the concept of using highest expertise available, the enclosure was produced collaboratively with the luxury furniture maker Tendo Mokko in Yamagata. As a result, TAD has achieved both improved sound quality as well as a visual with a feel and beautiful aesthetic worthy of the name “Reference” through the use of the SILENT enclosure, that has evolved further through the artisanal techniques of Tendo Mokko, the creator of numerous masterpieces, in response to orders from renowned creators all over the world.

A CST (Coherent Source Transducer) driver that embodies the ideal single point sound source concept TAD uses a CST driver for coaxial speakers that controls the phase and directivity of the drive unit across a wide frequency range. The use of a midrange cone controls the directional characteristics of the concentric mounted tweeter, thereby unifying the acoustic center of the tweeter and the midrange as well as reconciling the phase and directional characteristics through the crossover range.

This enables both ultra-wide range reproduction of 250Hz–100kHz and a direct-radiation pattern that neatly dampens uniformly across all bands. The result is extremely clear and stable imaging, a wide frequency response, and incredibly rich and natural sounding reproduction. Beryllium diaphragm processed with unique vapor deposition technique for tweeter and midrange The R1TX uses a beryllium diaphragm for the tweeter dome and midrange cone.

A vapor deposition technique uniquely developed by TAD and refined over many years, provides superior material strength and uniformity as well as high-frequency resonance damping. The midrange features a maximum-size 16 cm-diameter cone for the beryllium diaphragm to realize transparent sound across a wide frequency range. Moreover, TAD used their original computer-analysis optimization method HSDOM (Harmonized Synthetic Diaphragm Optimum Method) to design the tweeter’s shape, achieving accurate control of differential vibration and ultra-wide range reproduction up to 100 kHz.

Newly developed Woofers with a TLCC (Tri-Laminate Composite Cone) diaphragm The new R1TX woofers incorporate a “TLCC diaphragm” that achieves fast-response, clear, and rich reproduction with no coloration through a structure of lightweight, high-rigidity foamed acrylamide, which is used in aircrafts, sandwiched by aramid fibers, and resulting in improved strength and stiffness. The TAD engineering team reduced minor resonances in axisymmetric modes by molding the foamed acrylamide and aramid fibers separately as well as processing them with a lamination method that utilizes the anisotropy of woven fabric.

Furthermore, we have applied acoustic tuning creating a natural sound timbre in association with the CST driver. Woofers with OFGMS (Optimized Field Geometry Magnet Structure) circuit In order to always correctly reproduce audio waveforms, we use our original magnet-circuit short voice coil OFGMS circuit, which linearizes the magnetic flux density along the 33 mm long gap. This stabilizes operation during wide range amplitude and realizes high movement linearity.

Moreover, high linearity is maintained as we also use our original corrugation edge in the suspension components. A port system that applies TAD horn fluid design Air noise is effectively reduced by using a flare-shaped port system that is superbly aerodynamic. The unit operates stress-free even during large input and amplitude, producing clear bass with good S/N. SILENT (Structurally Inert Laminated Enclosure Technology) enclosure with high damper effect and strength The enclosure is made of a laminate structure that combines different materials, and its static and dynamic strength as well as damper effect is maximized by utilizing the merits of its frame and monocoque structure, for example by making the side walls a frame surrounded by strong panels.

The enclosure consists of a strong framework of 21 mm-thick birch plywood and a transverse bulkhead that is glued to 50 mm-thick side panels produced with high-frequency hot press forming. Moreover, by building on the teardrop form and rounding the shape of the speaker head, we increase strength, reduce sound diffraction anomalies, and eliminate unwanted resonance and standing waves inside the enclosure. Collaborating with luxury furniture maker Tendo Mokko to make the enclosure TAD designed and constructed the enclosure in collaboration with one of Japan’s most famous luxury furniture makers Tendo Mokko, which was founded in Tendo City, Yamagata in 1940.

The SILENT enclosure has become even stronger by utilizing Japanese traditional artisanal techniques during molding and processing. The new TAD-R1TX line-up now features two exterior colours derived from the rare mineral beryl, which is the raw material of the beryllium used for the diaphragm: “emerald black,” which is suggestive of a deep-green gem, and “beryl red,” which is suggestive of a red gem made of beryllium. Both are color tones replete with deep luster and elegance, and make the most of the beautiful feel of the natural wood, worthy of the name “Reference.”
