KENWOOD LS-880D

Commentary

A speaker system developed using Kenwood's technologies such as plasma diamond diaphragm and direct inner Class A suspension.

A 27 cm cone type woofer is installed in the low range.
The diaphragm is reinforced with New HR carbon and rib, and has a 3-layer structure sandwiched between pulp layers and high-quality resin layers. This increases rigidity and reduces the noise inherent in the material.
The drive system employs a voice coil composed of a magnet with a total magnetic flux of 92000 maxwell and a highly rigid aluminum bobbin.
In addition, it uses Kenwood's original Class A suspension with two suspensions. The two suspensions cancel each other's non-linear strain and realize linear motion of the diaphragm.

A 7.5 cm semi-dome type skoker is mounted in the middle area.
Ion-plated titanium is used for the diaphragm, and it is a semi-dome type that combines the characteristics of dome type and cone type. In addition, a high magnetic flux density magnetic circuit with a total magnetic flux of 46000 maxwell and a thermosetting adhesive aluminum wire voice coil are used for weight reduction and high efficiency.

A 2.5 cm dome type tweeter made of plasma diamond titanium is mounted in the high range.
This diaphragm is composed of a titanium base material with a diamond thin film ion-plated, and has high rigidity, no resonance point, and excellent heat radiation effect.
In addition, the edge part is placed inside the magnetic circuit, and a direct inner Class A suspension with bias added between upper and lower elastic bodies is adopted. Since there is no unnecessary radiation from the edge part, it has excellent transient characteristics and improves the linearity of low-level.

The enclosure has round baffles rounded on both sides to reduce diffraction effects and reduce distortion due to sound interference.

Equipped with an acoustic level control that can be adjusted according to the characteristics of the listening area.
