Cyrus is the name given to the higher-priced line of loudspeakers made by England's Mission Electronics. The entire Mission loudspeaker line includes six products under the Mission label and three under Cyrus. Mission also manufactures a wide range of electronics and CD players. The company has a long history of audio innovations, both in loudspeaker and electronic design. Among Mission's claimed "firsts" are the first polypropylene-cone drive-unit used in a product (1978), first widespread use of MDF loudspeaker enclosures (1981), and first CD player from a specialist manufacturer. Interestingly, Mission also makes IBM-compatible personal computers.
The $900/pair Cyrus 782 is a two-way design employing dual 7" (175mm) polypropylene-cone woofers and a single ¾" (19mm) fabric-dome tweeter. The drivers are arranged in a D'Appolito configuration to simulate point-source radiation characteristics. Both woofer and tweeter were designed from scratch by Mission. The polypropylene woofer cones include a "mineral loading" that reportedly increases cone rigidity, thus decreasing cone breakup. Additional woofer design features include a shaped pole piece to increase linearity during high cone excursions, rigid steel chassis to reduce driver resonances, and a tight tolerance between the voice-coil and magnet to increase sensitivity.
