Technics SB-MX100D

Commentary

A 2-way speaker system with high resolution and natural sound.

A 18 cm cone type woofer is installed in the low range.
This unit uses a composite mica diaphragm. By mixing pulp and aramid with mica, which is a material with high rigidity and high internal loss, the natural resonance of the material is suppressed, and excellent resolution, transparency and speed in the middle and low range are obtained. In addition, by coating the diaphragm with lacquer, high specific elastic modulus and internal loss are obtained.
In addition, Kynol fiber with excellent linearity of expansion and contraction is used for the damper material, and reproducibility of minute signals is improved by improving linearity.

A 2.5 cm dome type tweeter is installed in the high range.
The diaphragm has an over Le Dome shape with an elliptical cross section, which improves the upper limit frequencies by about 10% compared to the normal circular dome type. In addition, the pure mica used for the diaphragm is coated with diamond, which provides stable operation and extremely high resolution.

The front baffle is rounded to reduce response disturbance due to sound diffraction at the corner of the enclosure, and a separate baffle structure with a rubber gasket around the tweeter and slits at the top and bottom of the woofer is adopted to reduce resonance and incidental sound.
In addition, the exterior is finished with natural oak veneer, and by applying 5 layers of glossy coating, it is tuned so that the resonance of the cabinet itself does not muddy the music signal.

A convex pin type is adopted for the net cap to which the speaker net is attached to suppress the incidental sound caused by cavity resonance and reflection.

It uses a large network for bi-wiring.

Special speaker stand is sold separately.
This stand is designed to reduce unnecessary radiation, and the resonance of the stand itself is reduced by the four point support structure on the bottom.
