It is the speaker system which raised Haar Beth's original beautiful sound further, and also aimed at thorough reexamination in pursuit of realism and a clear feeling.

The 20cm corn type Woofer which adopted the original diaphragm of the establishment meter is carried in low-pass.
This corn is adopting the diaphragm process which blends three kinds of polymer and is arranged from the central part to a circumference part, and has solved the problem on the surface of a corn which is different near the central part and in a circumference part.
Furthermore, a voice coil is also made into an original structure which considered breathability, and the stabilization of temperature characteristics over a long period of time is attained.

The 2.5cm dome shape tweeter is carried in the high region.
This unit serves as a hard dome shape vapor-deposited to original T type yoke. moreover, ferrofluid cooling is adopted and the thermal diffusion nature of a voice coil is improved by the application of magnetic oil.

Original STS (Super Tuned Structure) is introduced into the enclosure design. An unnecessary vibration is dumped employing sound efficiently with weight, or not rigidity but the physical properties of the material itself and combination between MDF material with high hardness by considering it as the special sandwich construction which makes several materials from which Resonance and a stiffness differ stratify.
The bass-reflex port of enclosure is made into square form based on the repeated audition. Furthermore, the key point inside enclosure is dumped for the tar system material.

The Frameless Frame system is adopted as a net grill, different jersey materials from the former are used, the frame of a grill is inserted in the slot on the baffle, and the one disposition top with enclosure is planned. This is suppressing the influence on a high region to the minimum.

There was a stand for exclusive use as an option.
