In Sansui's continuing search for the "absolute" in audio reproduction, this handsome 4-way ,6-speaker system represents nothing less than a major triumph. It combines a powerful 70 watt handling ability with the finest in components and internal engineering for a totally new dimension in high fidelity purity and realism. Each of the SP-2000's six speakers is unique, yet all are designed and positioned in close relationship to the characteristics of Sansui's exclusive pipe-duct enclosure, 12dB/oct crossover network and 3-position level controls. The result is uncompromised lifelike stereo reproduction throughout a wide 30 to 20,000 Hz frequency response range. Every bit indicative of the SP-2000's rich performance and internal engineering is its specially selected walnut cabinetry. This wood has been precision-mitered, hand-crafted and finished in oil to blend in with the finest furniture.
The SP-2000 is the most brilliant 4-way speaker system we've made to date. Intended for audio perfectionists only, it incorporates a 12-inch woofer, 6-1/2 and 5-inch mid-ranges, two 2-inch horn tweeters and a 1-3/8-inch horn super tweeter.
Woofer
The massive magnet assembly, precision-made voice coil, specially selected cone materials and unique cloth-edge suspension assures the best possible linearity at the deepest bass levels. Built into Sansui's pipe-ducted bass reflex enclosure, this woofer deliveres full, solid bas at all amplitudes.
Mid-ranges
It is often said that the sound quality of mid-range speakers determines the value of a speaker system. Most speaker systems tend to neglect the mid-frequency range, giving too much care to both high and low ranges. The SP-2000 houses two rear-sealed mid-ranges with aluminum radiators for the faithful reproduction of sound, from that of strongly attacked percussion instruments to that of soft vocal music.
Tweeters
The two horn tweeters and one super tweeter give smooth, peak-free response beyond the upper limit of audibility, without coloration.
Speaker Designed for Natural sound
Speaker performance may be mechanically measured by laboratory instruments, but "live" sound must be proved by human ears and actual listening tests. Sansui speaker systems are designed on the basis of a wide variety of data obtained from repeated actual listening tests, as well as from laboratory tests. These tests are made in rooms of different dimensions, decors and construction materials. That's why Sansui speaker systems reproduce natural sound wherever they are installed.
Pipe-ducted Bass Reflex
The secret to the SP-2000's powerful bass reproduction can be traced to Sansui's exclusive pipe-duct. Generally, a bass reflex enclosure is said to generate "boomy" bass. But the SP-2000 assures outstanding low-frequency characteristics because the pip-duct system has been designed in close relation to the performance of the cloth-edge suspension woofer.
12 dB/oct Crossover Network
Sansui's exclusive 12 dB/oct crossover network with a large ferrite core transformer divides the woofer, mid-range, tweeter and super tweeter response perfectly and prevents interaction between the speakers at the crossover points.
3-position level Controls for Mid and High Ranges
These 3-position level controls enable you to tailor the response to the acoustics of your room without affecting the damping characteristics of the speakers.
Enclosure
One of the design guidas followed in building the SP-2000 was the assumption that the performance of a speaker system depends more on the enclosure than on the speakers themselves. Accordingly, the SP-2000 enclosure has been carefully constructed of hard chipboard for distortion-free reproduction at the highest power levels.
Acoustic Material
The SP-2000 is baffled, enclosed and damped with 1-inch thick corrugated fibre glass to prevent the harmful standing wave from occuring in the enclosure. Mutual interference between speakers is completely eliminated for clear sound reproduction.
Grille
The fine furniture quality of the SP-2000's hand-craved fretwork grille will enhance the beauty of your listening room. The enclosure is finished on all four sides for horizontal or vertical placement.
