SANSUI SP-65

Commentary

This speaker system uses a DL cone, which was created through repeated testing and development and listening test.

A 20 cm cone type unit is used for the low range.
The cone part uses a DL (double layer) cone with a special coating agent applied to pulp cone, which suppresses split vibration, expands the piston motion band, and reduces distortion.
Low-Q-up roll edge with dump material applied on both sides is used to lower the lowest resonance frequency.
In addition, a series 4-layer voice coil is used to smooth the attenuation in the high-frequency range and to eliminate exposure at high frequencies.

A 3.5 cm soft dome unit is used for the high-frequency band.
The diaphragm is made of vegetable fiber. It is braked by special damping agent and glass wool of micron fiber on the rear surface to prevent deformation of the diaphragm due to vibration and to reduce strain.
The voice coil is made of C. C. A. W. (copper coated aluminum wire).
In addition, strong aluminum die-cast is used for the frame.

The network employs an LC-type network with excellent transient characteristics and is equipped with 3 Klix/Klukš top continuous variable level control.

The enclosure is fully enclosed, with sufficient internal reinforcement and two types of sound absorbing materials for a crisp low sound.
A unique non-interference baffle plate is used for the baffle plate to eliminate interference caused by the radiation acoustic wave of the tweeter and improve phase characteristics.
