Features

Pure magnesium diaphragm

The diaphragm is made of pure magnesium (99.9% purity), a lightweight material with high internal loss and excellent acoustics, molded into a ridge-dome shape. The diaphragm provides clear and extended sound reproduction with a rich amount of information.

Alnico internal magnetic circuit

Alnico magnets are used in the magnetic circuit. Copper caps are placed on the pole piece to reduce current distortion while possessing high magnetic flux density for premium treble reproduction.

Uniquely developed foam drabber on the edge

The same UDRT-shaped foam drabber edge as the woofer is used. The woofer and tweeter tones are aligned to improve the sense of unity.

Equipped with diffuser

It is equipped with a stainless steel diffuser that improves the diffusion of high frequencies. It also features a beautiful appearance that also protects the diaphragm.
