Commentary

The Chorus series speaker system supports both portrait and landscape orientation.

Two 16.5 cm cone type woofers are installed in the low range.
These units use poly-glass diaphragms, which have been used only in high-end models. The surface of cellulose fiber cone with excellent resolution is coated with hollow fine particles of extremely hard silica glass resin with a special adhesive. The combination of cellulose with high internal loss and light weight and a highly synthetic silica glass layer enables smoother and more accurate sound wave propagation.
Butyl edge is used for the edge part.

A newly designed 2.6 cm inverted dome type tweeter called TPC is installed in the high range.
In this TPC, the voice coil is rigidly fixed to the center of the dome to improve energy propagation while maintaining mechanical coupling between moving parts. In addition, the diaphragm is made of titanium monoblock and is damped with 5 μ m thick polymer. In particular, linearity in the 15 kHz to 22 kHz band is taken into consideration. In addition, a foam ring is installed between the MAG top of the net plate and face plate to eliminate unnecessary vibration.
A phase plug is installed on the front of the unit to make sound wave diffusion uniform.

The enclosure is designed with a bass-reflex port called a laminar flow.
The front baffle is designed with a dark gray finish of highly rigid MDF material combined with a cherry finish cabinet.

Bi-wiring is supported.

It is compatible with the Chorus series common speaker stand sold separately.
