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.

Tannoy E11 loudspeaker

The Tannoy E11 ($349/pair) is the company's least-expensive model in a wide range of consumer loudspeakers. Tannoy is most often known for its professional models, especially their nearfield, dual-concentric monitors that have become de rigueur on the top of recording consoles. The E11 is a two-way, ported design with a 6.5" woofer and 1" dome tweeter. Both drivers are manufactured by Tannoy, instead of being sourced from a driver manufacturer. The woofer is made from a polyolefin co-polymer, a plastic material with high rigidity and good self-damping properties. To improve power handling and increase sensitivity, the voice-coil is edge-wound on a Kapton former. The surround appears to be made of butyl rubber.

NHT Model 1.3 loudspeaker

Now Hear This (NHT) was founded to produce low-cost loudspeakers a breed apart from the mass-market variety often found at the lower price points. Co-founder Ken Kantor has a long history in the hi-fi business as a designer at Acoustic Research, NAD, and as a design consultant to some large Japanese manufacturers. NHT's line ranges from the $180/pair Model Zero to the $1200 Model 100.

At $480/pair, the Model 1.3 is midway in NHT's product line. Finished in a gloss-black high-pressure laminate, the 1.3 is elegant, even beautiful, and is distinguished by its unusual angled front baffle. This design means that the rear baffle is nonparallel to the driver, thus reducing the amount of internal cabinet energy reflected back toward the woofer. This is said to improve imaging and midrange purity by reducing comb filtering. In addition, the angled baffle puts the listener directly on-axis with the loudspeakers pointing straight ahead. This increases the ratio of direct-to-reflected sound reaching the listener and further improves imaging.

The philosophy promoted by many mainstream stereo magazines (and thus often the belief of the general public) is that one should spend a minimum amount of one's hi-fi budget on electronics and front ends, and a maximum amount on loudspeakers. Since all electronics sound alike and it's the loudspeaker that really produces the sound, the highest overall performance is obtained by putting expensive loudspeakers at the end of a chain of inexpensive electronics. Cables? Don't waste your money.

As an equipment reviewer, I find it helpful to talk to audiophiles and music lovers about their systems and upgrade plans. Fortunately, Stereophile's computer supplier and troubleshooter, Michael Mandel, also happens to be an avid audiophile. I say "fortunately" because I rarely get a chance to talk to people who put down their hard-earned money for hi-fi components. Instead, I usually converse with equipment designers, technicians, and marketing types, hardly people who reflect the buying public. It is thus a valuable education to get feedback from real-world consumers to find out what kind of products they want, their priorities, and how much they're willing to spend for certain levels of performance. They have a view distinctly different from that of the often jaded reviewer who is used to enjoying the best (albeit temporarily) without agonizing over its cost.

During an Audio Engineering Society meeting where a former colleague of mine was giving an arcane technical discussion of the optical considerations of data retrieval from a Compact Disc, a longtime AES member whispered to me: "What happened to the good old days of AES meetings when we talked about things like tape bias and saturation?"

When a loudspeaker designer produces a world-class product, it is usually the result of years, perhaps decades, of experience gained from designing less ambitious products. To review a particular designer's product history is to witness the learning curve in action as both his skill and technology advance. Successfully battling the laws of physics to produce a truly exceptional loudspeaker is thus thought of as the domain of the seasoned veteran whose vast knowledge and experience culminate in the pinnacle of his career—a world-class loudspeaker. Moreover, it is just these designers, working their way up to their masterpiece, who are the most successful at getting an ambitious design right. The high-end loudspeaker business is littered with the remains of companies that attempted to build a first product far too lofty for their skills.

As a card-carrying member of the Audio Engineering Society and an avid audiophile, I was particularly disturbed by the ideas expressed at the 1990 AES Conference entitled "The Sound of Audio." (A report on the papers presented appears in this month's "Industry Update" column.) The tone of the three-day session in May was set during the Conference Chairman's opening remarks. He said that an AES conference on the sound of audio was "unusual" and "out of the mainstream." Further, he expressed a common underlying attitude among the AES that "audiophile claims" (of musical differences between components) have been "nagging us" and are "an annoyance."

The promise of "perfect sound forever," successfully foisted on an unwitting public by the Compact Disc's promoters, at first seemed to put an end to the audiophile's inexorable need to tweak a playback system's front end at the point of information retrieval. Several factors contributed to the demise of tweaking during the period when CD players began replacing turntables as the primary front-end signal source. First, the binary nature (ones and zeros) of digital audio would apparently preclude variations in playback sound quality due to imperfections in the recording medium. Second, if CD's sound was indeed "perfect," how could digital tweaking improve on perfection? Finally, CD players and discs presented an enigma to audiophiles accustomed to the more easily understood concept of a stylus wiggling in a phonograph groove. These conditions created a climate in which it was assumed that nothing in the optical and mechanical systems of a CD player could affect digital playback's musicality.
