TAD Labs Mirco Evolution One ME-1Tx

Further perfecting TAD’s sound delivery concepts of high-dimensional sound imaging and sound-field immersion coupled with an innate sense of musical cohesion and involvement.

Inheriting the design concept of TAD’s Evolution series, the TAD-ME-1 is equipped with a new 16-cm woofer and 9-cm CST1 Driver to achieve even more outstanding sound quality throughout an entire room and extremely sharp imaging.

It also incorporates TAD’s Bi-Directional ADS2 port, enabling the reproduction of natural, deep bass sound despite its compact size.

The TAD-ME1TX boasts TAD’s proprietary CST* driver, which controls the directivity of the concentrically mounted midrange and tweeter over an extended frequency range from the point of matching phase. TAD-ME1TX’s 9 cm CST driver achieves clear and solid imaging, as well as natural sound-field reproduction. The midrange cone controls the directional characteristic of the concentrically mounted tweeter to bring the phase and directivity of their output in line in the crossover region. The result is wide-range sound reproduction from 420 Hz to 60 kHz by the CST driver alone, while achieving a natural attenuation characteristic and directivity pattern across all bands.

The TAD-ME1TX uses a newly developed, light yet rigid 25 mm beryllium diaphragm for its tweeter, manufactured with our proprietary vapor deposition technique. We have applied our computer-analyzed optimization technique called Harmonized Synthetic Diaphragm Optimum Method (HSDOM) in designing the form of the diaphragm. This technique enables the precise control of the diaphragm’s divided vibrations and piston motions, which makes possible wide-range sound reproduction of up to 60 kHz.

The TAD-ME1TX comes in a SILENT (Structurally Inert Laminated Enclosure Technology) enclosure, which combines sturdy birch-plywood braces with medium-density fiberboard (MDF) panels having a high internal loss to provide superb structural strength and an outstanding low-resonance characteristic. The addition of 5 mm-thick steel panels to the right and left sides of the enclosure further reduces the vibration of the cabinet down to a minimum. Moreover, acoustic absorbent chosen and placed carefully inside the enclosure, based on meticulous analyses of internal standing waves, helps eliminate standing waves that would adversely affect the sound field and imaging performance of the speaker.

The midrange’s diaphragm made of magnesium alloy achieves lightweight and high internal loss properties. The combination of anodization and coating applied to the surface of the diaphragm gives it additional hardness and a yet greater internal loss. Combined with the suppression of even the smallest resonance arising from where a leading wire is connected to the voice coil, the result is clear, distortion-free reproduction in the midrange. In addition, the arm of the frame basket that houses a magnetic circuit has been redesigned to achieve much greater structural strength and allow smoother propagation of sound waves behind the midrange diaphragm.

As its predecessor, the TAD-ME1TX employs the Bidirectional Aero-Dynamic Slot (ADS) port design, which places slit-shaped ports (ducts) inside the right and left side-panels of the enclosure with flared openings to the front and rear to allow a smoother airflow through them.
This design helps reduce port noise generated at high amplitude levels and keeps internal standing waves from escaping from the ports, resulting in a rich, responsive bass. The symmetrically placed port openings, both laterally and along the front-rear axis, cancel out vibrations from the port movement to deliver a natural-sounding bass response.
