Reference One TX Speakers
TECHNOLOGICAL PROWESS AND ART COMBINED
Since its inception, the TAD Reference One has quickly become the established reference point for speaker systems in the new era of high definition audio. This ultra high end speaker system is based on highly advanced technology developed by TAD (Technical Audio Devices), creators of studio monitors favored by leading sound studios around the world. It employs carefully selected materials and parts, and benefits from scrupulous, even relentless, attention to detail, backed by our design theory and testing ability. The result is a sound field of flawless purity that achieves unprecedented professional audio artistry. The TAD Reference One realizes richly resonant sound of which has never been heard before.

|Special Features||CST* (Coherent Source Transducer)
The CST (Coherent Source Transducer) enables us to achieve our goal for the TAD Reference One: "Reproduction with controlled directivity over a wide frequency range from a single point with uniform phase". The design of the midrange cone is based on detailed calculations that result in the unique shape that produces superior acoustic characteristics and precise control of the directivity of the concentric mounted tweeter.
This configuration unifies the acoustic center of the tweeter and midrange and reconciles the phase and directional characteristics through the crossover range. The CST Driver is thus a large step forward for coaxial speakers, enabling ultra wide range reproduction of 250Hz to 100kHz, accompanied by a directivity pattern which neatly dampens without disruption across all bands. The result is extremely clear and stable imaging, a wide frequency response and incredibly rich and natural sounding reproduction. CST technology allows unprecedented wide-range reproduction and directivity control.
BEryllium - unique vapor deposition technique
BERYLLIUM - UNIQUE VAPOR DEPOSITION TECHNIQUE
The tweeter dome and midrange cone are made of beryllium, the lightest and most rigid of metals, which makes it a superior diaphragm material and boasts a history of more than 40 years of TAD achievements. The diaphragm is produced using a vapor deposition technique developed by TAD and refined over several decades. Providing strength and uniformity combined with high internal loss, the result is smooth, superior performance. The tweeter diaphragm shape is derived using an advanced optimization method based on HSDOM (Harmonized Synthetic Diaphragm Optimum Method) computer analysis. It accurately controls differential vibration produced by the diaphragm and shifts it out of the audible band, providing uniform response to as high as 100kHz. The large midrange cone features a direct radiation, vapor deposition beryllium diaphragm. The resulting sound is astonishingly transparent, direct and precise across a wide frequency range.
The beryllium used in Reference One is manufactured using vapor deposition, a unique technology of TAD. The advantage of vapor deposition is that the particles are bonded while maintaining their molecular composition, so that it has both high rigidity and internal loss that cannot be imagined as a metal. Furthermore, the production of beryllium by vapor deposition is the only in the world.
TLCC* (Tri-Laminate Composite Cone)
The TAD Reference One bass driver is driven by an oversized, 100mm diameter voice coil and large neodymium magnet. To handle the force generated by this motor, the diaphragm must be very strong and stiff. We were able to achieve ideal physical properties including structural body strength, by using a TLCC (Tri-Laminate Composite Cone) diaphragm that has a unique triple laminated construction: a core of foamed acrylamide sandwiched front and rear by direction-oriented aramid fibers. To eliminate drive loss for more efficient power handling, the dust cap uses the same material. Furthermore, by joining the cone, dust cap and voice coil at a single point, the voice coil drive is transmitted directly to the cone. The result is not only fast response and clear bass, but low coloration sound extending through to the midrange.
OFGMS* (*Optimized Field Geometry Magnet Structure)
OFGMS MAGNETIC CIRCUIT
In order to match the high speed response and power linearity of the beryllium diaphragm CST Driver, we sought to improve the low-bass reproduction linearity of the bass driver. In order to correctly reproduce signal waveforms, especially at high excursions, we developed the short voice coil OFGMS (Optimized Field Geometry Magnet Structure) magnetic circuit.
In a conventional magnetic circuit, the magnetic resistance of the pole piece impacts the magnetic flux density distribution within the gap. To avoid this compromise, the OFGMS magnetic circuit has a unique slit in the top plate that equalizes the flux path distribution and linearizes the magnetic flux density along 33mm (1.29 in.) long gap. In this way, the 25cm (10 in.) woofer unit achieves excellent drive capability and linear drive characteristics over its entire 26mm (1.02 in.) range of motion.
SILENT* Enclosure (*Structurally Inert Laminated Enclosure Technology)
SILENT ENCLOSURE - UNIQUE STRUCTURE
The TAD Reference One features our new SILENT (Structurally Inert Laminated Enclosure Technology) cabinet: the ultimate in elegant curves and immense stability. It is constructed from carefully selected materials to resonances, in order that the superior performance of the drive unit is maintained to the maximum degree. The basis of our efforts to eliminate resonance is the strong enclosure design, inspired by the structural theory of aircraft wings and ships. The structure consists of a strong framework with a skeleton having a 21mm (0.9 in.) thick birch plywood transverse bulkhead. It is clad with a hybrid of materials that combine 50mm (2 in.) thick side panels made by high frequency hot press forming glued to CNC machined plywood panels with a maximum thickness of 137mm (5.7 in.). Use of the teardrop form, a design incorporating the concept of hydrodynamics in acoustic engineering, minimizes sound diffraction anomalies. Finally, by applying ABD technology, a technique whereby the dual bass drivers are located so as to eliminate the formation of higher frequency standing waves inside the enclosure that negatively impact sound quality, we achieved a revolutionary enclosure.
Aerodynamic Port System
AERODYNAMIC PORT SYSTEM
The bass reflex port, utilizes the design concept of the compression driver and horn seen in the TAD systems used by professionals. It features an aerodynamic port system based on the theory of precise fluid design. Its performance is such that that it produces absolutely no air noise, even when the woofer unit is driven at the limit of its excursion range. Superb control of air flow and pressure inside the port greatly contributes to the realization of deep bass reproduction with unprecedented clarity.
