The 3 way speaker system which adopted the multicellar horn as the high region.
The 30cm unit which adopted FB cone by an original process is adopted as low-pass.
The ferrite magnet is used for the magnetic circuit.
The 12cm unit which adopted FB cone like low-pass is adopted as the mid range.
As for this unit, the ferrite magnet is adopted as the magnetic circuit.
Furthermore, the cone rear is used as perfect closed mold in order to prevent the back pressure from a Woofer.
The multicellar horn is adopted as a high region.
The level control is carried in the front convenient to operate it.
Moreover, a switchpoint change on the back can also use the multi-amplifier scheme of two channels and three channels.
The enclosure serves as oil finish finish of the walnut which employed the beauty of native wood efficiently.
