What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Sansui SP-200

 Creative Speaker Design Based on Repeated Hearing Tests as Well as on Laboratory Test
Speaker performance may be well measured by laboratory instrumentation. But "live" sound must be proved by human ears or hearing test. Thus, Sansui's speaker system is designed on the basis of a wide variety of data obtained from repeated actual test as well as from laboratory tests. These tests have been made not only in our modern laboratory  and test rooms made of different construction materials. That's why Sansui's SP series system can reproduce lifelike stereo sound wherever it may be installed.

3-way 5-speaker system
The SP-200 is a full range 3-way 5-speaker system consisting of a 12-inch woofer, two 5-inch midrange speakers and two 2-inch horn type tweeters. It can faithfully reproduce deep, rich lows, and clean, transparent highs, and all the tones in between.
Woofer - Designed to match the "pipe-ducted" bass reflex type enclosure. Its edge, paper cone, damper and other components are all designed to give the best linearity even at any big amplitudes, assuring good damping characteristic at low frequencies. Equipped with specially designed level control.

Midrange - It is  often said that the quality of midrange determines the value of a speaker system. Generally many speaker systems tend to neglect the midrange, giving too much care to hig and low frequency ranges. The Sp-200 is provided with two 5" rear-sealed hgih-performance midranges whose powerful magnetic circuit prevents any interference with the woofer. They can reproduce a live sound of strongly attacked percussion instruments as if they were played just before you.

Tweeters - the clear, clean, transparent highs are a measure of a performance of a speaker system. The SP-200 posesses two horn type speakers whose frequency response is more than 20,000 Hz  and whose transient response is excelent, too. You can enjoy romantic mood of strings as it is.
 Faithful Reproduction of Bass Tones by Pipe-Ducted Bass Reflex
The Sansui's exclusice "pipe-ducted" bass reflex enclosure helps reproduce original bass tones faithfully. The bass sounds that are boomy or exaggerated in a limited bass range never deserve the name of Hi-Fi. In order to match the pipe-duct characteristics, the woofer is designed to lower "f₀" greatly by the cross edge, assuring the faithfull reproduction of the lowest

Transformer Type 12 dB Crossover Network
Here's the Sansui's exclusive knowhow of the transformer. The transformer type network is designed to let each of woofer, midranges and tweeters function in its most suitable frequency range, assuring clear sound even at the crossover points.

Specially Designed Level Control
The Sansui's exclusive transformer-type crossover network changed the level control from the conventional volume-type attenuator to the latest tap-type control whose operation does not influence the damping characteristics at all. This level control has three positions to adjust clear, natural and soft. The "natural" position is for the average rooms; "clear" for the rooms where the highs are swallowed up and the lows are exaggerated and "soft" for rooms where the lows are swallowed up and the highs are  exaggerated.
 25 mm Thick Glass Wool Used as Sound Absorbment
25 mm thick glass wool with the highest sound absorbing coefficient possible prevents the standing wave from occuring in the enclosure. As a result, the mutual interference of the speakers is completely eliminated.

Beautifully Finished Walnut Enclosure
The enclosure is meda of high-density tip boards of 21 mm in thickness and beautifully finished in walnut. Due to its structural design and select materials it has unsurpassed durability.

Deluxe hand-Carved Speaker Grill
The speaker grill is a fruit of an exquisite combination of Japanese traditional craftsmanship and European elegant color and design. It will enhance the beauty of your living room. What's more, it helps produce better quality of sounds.

Interference-Free Positioning of Speaker
Although the installation of two or more speakers in one box often leads to the mutualinterference between them, the Sp series system splved such a problem through years of our researches on the positioning of the speakers.
