TAD'S POINT-SOURCE SOUND PHILOSOPHY. RE-DEFINED.
With the flagship TAD Reference One, TAD gained the wholehearted trust and respect of many of the world’s top artists and engineers. As the final goal of the point-source sound idea, it was created by merging advanced technologies with our engineers’ experience in order to achieve the ideal sound in a dwelling space. Now, TAD have reached a new zenith with the TAD Compact Reference, which takes advantage of all of the top-level technologies that went into the flagship models. Our objective was to achieve, in a compact size, point-source sound of such high quality that listeners will forget about the existence of the speaker. Its extraordinarily resonant sound will surely exceed your expectations.
The CST (Coherent Source Transducer) has enabled us to achieve our goal for the TAD Compact Reference: reproduction with controlled directivity over a wide range from a single point with uniform phase. The design of the midrange cone is based on detailed calculations, so not only does it have superior acoustic characteristics, but it also controls the directivity performance of the tweeter due to the concentric configuration. This 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.
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 one which boasts a history of more than 30 years of TAD achievements. The diaphragm is produced using a vapor deposition technique developed by TAD and refined over many years. It provides strength and uniformity, combined with high internal loss, for smooth superior performance. The tweeter diaphragm shape is derived by 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 moves it out of the audible band, providing 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 CST Driver is mounted into a high-stiffness enclosure that is precisely shaped to minimize the diffraction of the radiated sound. In order to maximize the capability of the CST driver, we developed new ISO (isolation) technology. This involves including a mechanism to block vibration from the driver unit entering the enclosure, thus structurally separating the CST Driver from the enclosure. The CST Driver, with its powerful drive capability, is prevented from exciting the enclosure, thus reducing the radiation of secondary sound. It also limits the influence of the energy from the powerful bass drivers. Delivering only sound radiated from the CST Driver diaphragm improves resolution to convey accurate detail, allowing, for example, the differences in tone color that vary subtly according to how the performers play or sing, to be heard with unmatched clarity.
LOW LOSS, HIGH LINEARITY
The bass driver was designed to achieve total linearity of the magnetic circuit, diaphragm and suspension. The magnetic circuit features our unique short voice coil OFGMS (Optimized Field Geometry Magnet Structure). With a long gap of 20mm (0.8 in.), it linearizes the magnetic flux density along the gap. This stabilizes drive performance from small to large amplitudes, achieving high linearity and consistently accurate waveform reproduction.
The TLCC (Tri-Laminate Composite Cone) aramid diaphragm has a triple-laminated construction that provides near ideal physical properties. It delivers rich and clear low-bass with a mid-bass free of coloration. The suspension system employs TAD’s traditional corrugated edge, further contributing to the high linearity.
SILENT ENCLOSURE - ULTIMATE STRENGTH
The SILENT (Structurally Inert Laminated Enclosure Technology) cabinet, inherited from the TAD Reference One, is a compact 63cm (25 in.) in height. It has a strong internal framework formed by 21mm (0.9 in.) thick CNC machined birch plywood clad with high frequency hot press formed laminated MDF panels, resulting in extremely high strength. The 27.5mm (1.1 in.) thick aluminum base lowers the center of gravity and stabilizes the cabinet against the forces generated by the powerful bass driver motor system. Combining differing materials in this way both distributes and minimizes the enclosure resonances and achieves high vibration control. Its flowing teardrop shape minimizes sound diffraction and unwanted resonance from internal standing waves. With a beautiful piano-like finish of natural Pommele Sapele wood, the cabinet imparts an air of elegant craftsmanship.
AERODYNAMIC PORT SYSTEM
In order to make the most of the linear performance of the 20cm (8.0 in.) bass driver and its suspension, the bass reflex port is aerodynamically optimized based on precise fluid design technology refined by TAD professionals. This flare-shaped port produces absolutely no air noise or rectification effects, even when the bass driver unit is driven at the limit of its excursion range, achieving deep, clear bass.
The enclosure is beautifully finished with natural Pommele Sapele wood that imparts an artistic air of elegance.
