Commentary

A bookshelf type speaker system of the CDM NT series which is the successor of the CDM SE series.

A 16.5 cm cone type woofer is installed in the low range.
The diaphragm of this unit uses a Kevlar cone to reduce the standing wave generated in the cone. In addition, the center cap is equipped with a bullet-shaped fading plug to improve the diffusivity in the middle and high regions, making the connection between drive units smoother.
A copper sheath is also added to the magnetic circuit.

A 2.5 cm metal dome type tweeter is installed in the high range.
This unit is a tube-loading tweeter used in the Nautilus 800 series, which effectively absorbs unwanted sound radiation from behind the diaphragm, enabling higher-quality high-frequency playback.

In the network section, the filters for woofer and tweeter are separated into separate boards to eliminate mutual interference between each circuit.
Air-core choke coils and polypropylene film capacitors are used for the circuit elements.

The enclosure uses a bass reflex system.
The CDM NT series enhances the exposure of the tweeter by exposure of the tweeter, enhances the sound spread and the sense of freedom, and improves the total system performance by aligning the time with the woofer.
The bass reflex port has a number of small depressions in the opening that act like the surface of a golf ball and, in combination with hydrodynamically studied shapes, improve air turbulence in the port.

The exterior has a natural veneer finish and comes in three variations : black ash, red cherry and cherry.

There was a special speaker stand FS-CDM as an option sold separately.
This stand can be filled with silica sand in the legs to increase stability and damping and improve sound quality.
There are 2 color variations, black and silver.
