The design of the midrange cone is based on detailed calculations that result in a unique shape that produces superior acoustic characteristics and precise control of the directivity of the concentric mounted tweeter.\u003cbr\u003eThis configuration unifies the acoustic centre of the tweeter and midrange and reconciles phase and directional characteristics through the crossover range. The CST Driver is a major step forward for coaxial speakers, enabling ultra wide range reproduction from 250 Hz to 100 kHz, accompanied by a directivity pattern that dampens smoothly without disruption across all bands. The result is extremely clear and stable imaging, wide frequency response, and natural reproduction. CST technology enables wide-range reproduction and directivity control.\u003c\/p\u003e\n\u003ch3\u003eBeryllium – Unique Vapour Deposition Technique\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eTo realize unmatched quality and precision.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe tweeter dome and midrange cone are made of beryllium, the lightest and most rigid of metals, making it a superior diaphragm material with over 40 years of TAD development. The diaphragm is produced using a vapour deposition technique developed and refined over decades. This provides strength and uniformity combined with high internal loss, resulting in smooth performance. The tweeter diaphragm shape is derived using an optimisation method based on HSDOM (Harmonised Synthetic Diaphragm Optimum Method) computer analysis. It controls differential vibration and shifts it out of the audible band, providing uniform response up to 100 kHz. The midrange cone features a direct radiation vapour deposition beryllium diaphragm, producing transparent and precise sound.\u003c\/p\u003e\n\u003cp\u003eThe beryllium used in Reference One is manufactured using vapour deposition, a unique TAD technology. The advantage is that particles are bonded while maintaining molecular composition, achieving both high rigidity and internal loss.

ISO (isolation) drive technology prevents vibration from entering the enclosure by structurally separating the driver from the cabinet. This reduces secondary radiation and limits the influence of energy from the bass drivers.

The TLCC (Tri-Laminate Composite Cone) diaphragm uses a triple-layer construction: foamed acrylamide core sandwiched by aramid fibres. The dust cap uses the same material, and the cone, dust cap, and voice coil are joined at a single point for direct transmission. The result is fast response, clear bass, and low coloration into the midrange.\u003c\/p\u003e\n\u003ch3\u003eSilent Enclosure – Unique Structure\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eTo raise strength to the ultimate level.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe SILENT (Structurally Inert Laminated Enclosure Technology) cabinet uses a rigid curved structure designed to minimise resonance.

First, we have chosen the BTL (bridged transformerless) configuration as a basis for achieving total symmetry. Second, we have meticulously examined and optimised every aspect of amplifier design—from input through to output—which led to the fully symmetrical design, right down to the circuit topology and PCB boards, including the twin power transformers and the parallel-positioned electrolytic capacitors. All these elements are designed to be symmetric with regard to the effects of temperature changes, magnetic fields, and subtle vibration inside the case.\u003c\/p\u003e\n\u003ch3\u003eElaborate Vibration-Suppressing Technology\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThe newly designed cast-aluminium chassis suppresses even the slightest vibrations.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe M700 and M700S employ a newly designed cast-aluminium chassis that boasts a high internal loss factor for vibration, eliminating inherent sympathetic vibration at unwanted frequencies. Components are laid out optimally inside the chassis to stubbornly resist vibrations induced by sound pressure from a loudspeaker system. The low-impedance aluminium chassis demonstrates high electrical stability. Moreover, these amplifiers are supported by four height-adjustable spike feet, each having a single point of contact with the surface on which it stands. This ingenious design keeps vibration transmitted through the floor from affecting the components inside the case and ensures delicate audio signals are not masked by vibration-induced distortion. The result is more condensed and energetic audio reproduction while retaining the spatial nuance of the music.\u003c\/p\u003e\n\u003ch3\u003eLower Centre of Gravity\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRedesigned wide-stance construction provides a solid base that suppresses resonance vibration.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe wide-stance chassis construction, inherited from the TAD-M600 power amplifier, was upgraded to lower the already low centre of gravity of the whole unit by optimising the slant angle of the four feet at the corners.
