Sansui has three good things (and one bad thing) to tell you about the SP-20000 three-way, floorstanding speaker system introduced in 1973. First, the bad thing: if you play bad music through it, you hear bad music from it. What could be more fair ? The SP-20000 is a full-bodied speaker system entirely without a "personality" of it's own. That's good. The sound waves it puts out are exact conversions of the electrical impulses it receives from your amplifier or receiver. Thus, good or bad, the material you feed it is reproduced accurately and objectively as the medium of high fidelity can achieve. When you hear the results you'll definitely agree that this is good thing number one. Good thing number two is the fact that two of its three active speaker drivers employ a revolutionary Sansui development called the Direct-Drive Ring Diaphragm - or DDRD for short - to improve phase response, transient response and frequency response. The tweeter and midrange units in the SP-20000 are the first commercially available speakers to use this unique system where the voice coil is the diaphragm, and vice versa. Good thing number three is that the total design of the SP-20000 is integrated right down to the most minute detail. A precision-engineered "passive radiator" woofer is included to smooth and enrich the lows. The crossover and level control system is accurate and extremely flexible. The long-excursion, free-surround woofer is capable of very flat (linear) response at all input levels with reduced intermodulation distortion. And to wrap it up, the SP-20000's sensitivity (93dB/m/W, which is high but not too high) means that inputs from the exceptionally big peak of 100 watts clear down to low-power signals are handled efficiently at any listening level.
The clean and linear musical reproduction of the SP-20000 goes for any kind of music, from bubblegum to Bartok and from jug bands to symphonies. Sansui markets the SP-20000 by the pair, the right-channel unit is a mirror-image of the left-channel unit in terms of speaker placement. Each matched pair of SP-20000 comes with a pair of two-way speaker stands of attractive and strong aluminum tubing. Speakers may be positioned flat or on a slght angle.
