B&W Nautilus 803
¥ 400,000 (1 unit, released in 1998)
Nautilus series of Middle Class toll-boy speaker systems.
Two 18 cm cone type woofers are installed in the lower range.
Paper / Kevlar composite cone is used for the diaphragm.
The mid-range features an edgeless 15 cm cone mid-range.
The diaphragm uses a Kevlar cone the diaphragm. The unique FST improves the response time of the cone and the completeness of sound transmission to maximize the effect of Kevlar. The frame is designed to minimize the impedance to airflow from the rear of the driver.
A 2.5 cm metal dome type tweeter is installed in the high range.
The enclosure has a curved cabinet structure and uses a bass reflex system.
In addition, a matrix structure is adopted inside, and the cabinet is reinforced from the inside by a three dimensional honeycomb structure to suppress the coloring.

A speaker terminal made by WBT is used for the speaker terminal.
