Commentary
This is a tall boy type speaker system that combines the richless of N805 and the sharpness of N803 while keeping the footprint as small as N805.
Two 16.5 cm cone type woofers are installed in the low range.
Paper / Kevlar composite cone is used for the diaphragm.
It has a 15 cm cone type mid-range in the 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.
There are 3 variations of the finish of the exterior, black ash, red cherry and cherry.
