Sansui XL-900C (1983) | Digital Acoustic

 

Sansui XL-900C (1983) | Digital Acoustic

With the advent of Compact Discs and other digital programs, conventional speaker diaphragms were found to be not up to the task. Response was not fast enough, and they couldn't handle the powerful transients and extra wide dynamic range. What was needed was a diaphragm material that was light yet rigid, anti-resonant, and able to absorb vibrations - properties that were thought to be mutually exclusive. Sansui's research efforts led to the development of two radically new diaphragm designs that provide nearly ideal proper-ties. They are TCCF (Tri-Composite Carbon Fiber) and PM-C (Polypropylene, Mica and Carbon). Enter the XL-900C TCCF 3-Way Speaker System. Thanks to the light yet rigid TCCF (Tri-Composite Carbon Fiber) woofer diaphragm, this speaker system is ideal for new digital program material. Transients and presence are both superb, making listening an exciting new sonic experience. Bass thunders when it is asked to, and treble is sparklingly clean. It is equipped with a 320mm TCCF cone woofer, Low-mass 60mm ceramic hard dome midrange and a 25mm Super Titanium hard dome tweeter for flat response, wide frequency range and wide dispersion. Rounded cornered front baffle for low diffraction and better sound definition. Low-loss, low-coloration network. Maximum input, 180 watts.
