HLS series speaker system.

A 16.5 cm cone type woofer is installed in the low range.
Polypropylene cone is used for the diaphragm, and newly developed co-injection molding technology is introduced. By fusing and integrating the cone and rubber edge, the acoustic loss generated at the joint with the edge is reduced.

A combination of a 1 cm dome tweeter and a constant directivity horn is installed in the high range.
A polycarbonate dome is used for the vibration plate of the tweeter, and a ferrofluid cooling mechanism with magnetic fluid injected into the voice coil gap improves cooling efficiency and ensures high input resistance that can withstand high-power drives.
The constant directivity horn is designed to solve the problem that high frequency characteristics are degraded at off-axis positions. It accurately controls the high frequency range radiated from the tweeter with a horn with constant directivity. Even at off-axis positions, it can listen with the same frequency balance as on the axis. In addition, since the sound does not wrap around or reflect on the ceiling or wall outside the listening area, the original sound of the source can be heard more accurately. It also contributes to improving the efficiency of the tweeter.

It has a magnetic shield design.

The enclosure uses a rear bass reflex system.
It adopts a rear bass reflex system with a bass reflex port on the back, and the sound is optimized at a position where the speaker is at least 5 cm away from the rear wall surface.
In addition, in order to eliminate the effect of resonance on sound, precision reinforcement and assembly are carried out using original simulation analysis capable of cutting to 1 micron precision, and panel vibration is reduced to 1 / 10 compared with conventional products, eliminating the occurrence of colorization.

The speaker terminal uses a binding post type corresponding to a banana plug.
