A speaker system developed as a monitor speaker for professional use.

A 9 cm cone type woofer is installed in the low range.
This unit uses a ribbon-shaped aluminum alloy Mugi the Cat that looks like a string wound around a spinning top, and a sandwiched cone that covers both sides with thin sheets that have undergone electrolytic coating treatment. This structure provides excellent heat conduction characteristics and effectively reduces harmful split resonance through internal losses. The cone and dust cap are assembled with a thermally conductive bonding agent so that the heat generated in the voice coil is effectively dissipated. This greatly reduces the temperature rise coefficient and eliminates the power linearity degradation caused by the increased resistance of the coil copper wire.

A 2.5 cm dome type tweeter is installed in the high range.
The unit features a copper-plated aluminum voice coil, heat-sealed to a magnesium alloy dome, and a magnetic fluid filled between the magnet and voice coil to provide effective damping and cooling for sharp playback sound.

Silver solder is used for the network part.

The enclosure uses a bass reflex system.
There are multiple finishes and there are 3 variations of black texture, rose wood and piano black.

There was a speaker stand sold separately.
This stand is a heavy weight design with a ball-sized steel ball filled in the hollow of the column.
