MIROAK-B(Brass)
The silver color of the aluminum and the gold from the brass are very cool.
The brass is not coated so you can enjoy the aging of brass.
It has thicker and heavier mid-low range than MIROAK-Wood.
It is less sharp than MIROAK-S but mild and glossy sound. The mid-high range in particular has a gorgeous sound.
It is a very rich sound.
