Pioneer S-LH5a
¥ 68,000 (1 unit, released in 1998)
Commentary
Based on the S-LH5, all parts were thoroughly reviewed and improved to complete the speaker system.
A 22 cm diameter linear power unit is used for the low-frequency unit.
This unit is made of the same material as TAD corn paper, is resistant to flexural vibration, and is treated with special treatment. In addition, by reviewing the ring material of the outermost circumference of corn paper and the foaming ratio, it contributes to lighter weight, higher sensitivity, and flatter frequency characteristics.
The voice coil uses an edge-wise voice coil with increased density and magnetic efficiency, and the frame uses a high-strength aluminum die-cast frame.
A horn type is used for the high range.
For the driver, we have further improved the high-efficiency rear compression driver with TAD design know-how, and by placing magnetic fluid in the magnetic gap, cavity resonance in the lower part of the voice coil.
The AFAST-SZ horn has a round opening for uniform directivity in all directions, and an acoustic tube is installed on the horn wall to absorb resonance.
By making the opening diameters of the high and low area units uniform, the connection between directivity, energy and phase is improved.
Equipped with an attenuator that can be selected from 3 positions of Clear & Rich, Clear and Rich according to the setting.
Light-colored wood-grain 6-side finish, fine tuning enclosure is adopted.
It is equipped with a gold plated input terminal that can be connected by biwiring.
Two speaker cables for bi-wiring of OFC structure with core wires of special twist structure are included.
