LS-11
Commentary

This small speaker system was developed with advanced technology based on the concept of digital compact high-performance.

A 19 cm cone type woofer is installed in the low range.
The diaphragm uses New HR Carbon, which is reinforced by three dimensional cross-linking of carbon fibers.
In addition, the voice coil is designed to be highly resistant to input by combining materials with excellent heat resistance. In addition, a strong resonance dispersion high rigidity aluminum die-cast frame is used to eliminate noise turbidity due to unwanted resonance.
The edge is also a dual structure of different materials to realize linear motion of the diaphragm over a long period of time.

The mid-range is equipped with an 8 cm semi-boom coker.
An ultra-lightweight cone is used for the base of the diaphragm, and the chamber is a sandwich structure with both sides of an aluminum substrate treated with hard ceramics.
In addition, a magnetic circuit using a cancel magnet is adopted.

A 1.6 cm hard dome tweeter is installed in the high range.
A plasma diamond diaphragm using Kenwood's proprietary technology is used for the diaphragm. This diaphragm made of a composite material of titanium and diamond has features such as high rigidity, light weight, no resonance point, and high heat radiation effect.
In addition, the diaphragm ring and edge ring are attached to the diaphragm with ultra-hard resin with high heat resistance, and the diaphragm and edge part are integrated, and strontium magnet and cancel magnet are used for the magnet.

Equipped with continuously variable acoustic level control, it can be adjusted according to the condition of the room.

The enclosure is a round baffle to reduce diffraction effects.
In addition, the opening of the bass reflex duct is rounded with a special kaboo to prevent unnecessary noise caused by air coming and going.

The network section takes into consideration the details such as a printed circuit board with band separation 1-point earth and Ritz pattern, and a coil arrangement of three band complete separation to eliminate network crosstalk.

There was a special speaker stand sold separately.
