KENWOOD LS-11EX

Commentary

This speaker system is designed to acquire a wide frequency band and rich expressive power by allowing each unit to have room for its desired breath.

A 19 cm cone type woofer is installed in the low range.
The diaphragm is made of Dyneema fiber, which is lighter than water and has the same sound velocity as carbon and has the same internal loss as paper, and Cloth-dyneema made of flat fiber and plastic made of carbon fiber with high elastic modulus arranged in longitudinal and transverse order.
In addition, the main magnet is φ 90 and the sub magnet is φ 75.

The mid-range is equipped with an 8 cm semi-dome type squaker, and the high-range is equipped with a 1.6 cm titanium dome type tweeter.
Each unit uses a spherical wave horn baffle to reduce the reflection, interference, and diffraction of sound waves from the diaphragm and improve directional characteristics in the high frequency band, which tends to be more palatable.
In addition, a new cycloid curve has been adopted for the dome part of the Scoker, and excellent rising characteristics have been obtained while maintaining good directivity. In addition, the smooth vibration plate amplitude has been realized by the smooth release of back pressure by the adoption of an air bleed yoke.

Aluminum die-cast frame is used for the frame of each unit.

Although the enclosure is 3-way, it is compact and round baffle to make it closer to the point sound source and improve orientation. In addition, the depth is sufficient to confirm the content volume of 14.2L and the rear duct is adopted to improve low-frequency reproduction.
The baffle plate thickness is 30 mm, and the plate thickness of the main body and the plate thickness of the back are 18 mm.

The network is distributed with three network circuits for low, middle, and high frequencies to minimize signal interference caused by magnetic reciprocal induction between coils and capacitors of network parts.
We have also adopted Ritz pattern printed circuit boards and German-made film capacitors.

Gold plated input terminal corresponding to banana terminal is adopted.

There was a special speaker stand sold separately.
