Pioneer S-1000twin
220,000yen(one set, the 1989 release)

The speaker system which followed the technology cultivated by the studio monitor for pros, the development of EXCLUSIVE S5, etc., and was developed making full use of the still more original technology or the wave-front control technology.

The vertical twin which has arranged two Woofers up and down focusing on a tweeter is adopted.
Since the sound of the whole region from low-pass to a high region is emitted focusing on a tweeter by this, a rich feeling of sound field and a clear image lateralization are obtained.
This technology was developed further, and a new wave-front control technology is developed and introduced.
This is what solved scientifically how the wave of the sound from a speaker would spread and would reach to a listener's ear,"The energy time of a Woofer and a tweeter is controlled on a time base,"The enhancement is carried out to the point in the point of "controlling the directivity of a Woofer and a tweeter", "controlling electric phases, such as a network,", and "being control す about a wave-front diffraction by baffle form."

A 20cm cone type Woofer is adopted as low-pass.
The magnetic circuit by the AlNiCo-Magnet made to raise about 12% by an S-99twin ratio is adopted as a magnetic circuit.
Moreover, the diaphragm adopted what laminated the high polymer film as the pulp cone currently used in the TAD unit, and has given CRA (Cap Resonance Absorber) to the center cap like S5.
Since zinc die-casting is adopted as a frame and it has the specific gravity of 2.6 times of aluminum in it, high rigidity has been acquired.

the W.F. (wave front) director caused for the same quality of the material as EXCLUSIVE S5 to carry out acer-mono laminate shaving appearance to a 3cm dome shape tweeter is employed as a high region.
The wave front in a listener's listening location is coincided by performing a control of the time base which adjusts spatial relationship with a Woofer, and the directive control by horn form.
Moreover, the ceramic graphite diaphragm of 99.9% of a carbon purity is adopted as a diaphragm, and the AlNiCo-Magnet is used for a magnetic circuit.

Each unit is fixed to the interior of an enclosure, in order that each unit may have adopted the mid ship mounting scheme and may not tell an oscillation of a unit to a baffle.
Furthermore, the shielding frame which suppresses the floating top who suppresses an unnecessary oscillation of a top plate, and the unnecessary oscillation which gets across to a frame is putting into practice and pursuing no vibrating and absent-resonance-ization over a systemwide.

The network made the Woofer circuitry and the tweeter circuitry become independent, and especially the interconnection with a tweeter is direct connected with a calking sticking-by-pressure product line.
Moreover, mounting of each element also performs a vibration proof treatment, and it is arranged so that it may not be influenced by a crosstalk.

The enclosure used the real wood of the walnut and has given oil stainless steel finish.
Furthermore, a saran network is formed into flat surface with a baffle side, and since sound is tuned up in the status that it equipped with the saran network, he can enjoy himself, with a network attached.
Moreover, the unnecessary radiation sound (mid-range component) from a duct was avoided, and the backplane duct is adopted.
Furthermore, the interference of an opening is prevented by attaching sound-absorption felt to an opening.

The terminal in which a bi-wiring interconnection is possible is adopted as an input terminal.

A spike and felt are attached in order to correspond to floors, such as a flooring and a carpet.

The name plate is made from maple.
