Three-Way, Floorstanding Speaker

Never before has entry-level performance been this high. The Primus 360's twin 6.50" woofers, 4.00" midrange, and 0.75" tweeter all benefit from a proprietary transducer technology evolved from Infinity's top-of-the-line speakers to bring you dramatically reduced distortion and more natural, detailed sound.

Top of the Primus Line

With the Primus 360, Infinity's engineers have accomplished the ideal synthesis of technology, performance, design, and affordability destined to transport your home entertainment experience to a higher level. When you listen to the sound produced by this top of the Primus line's twin 6.50" woofers, 4.00" midrange, and 0.75" tweeter, you'll encounter a level of realism and subtly beyond what you've ever known before--even in music and movie soundtracks you know by heart. Then look at the Primus 360. You'll be struck by the modesty of a purely functional design that's also pleasing to the eye. All of this, allied with Infinity's tradition of excellence in sound reproduction, makes the cost of this speaker all the more amazing.

High Technology Derived From Premium Speakers

Infinity's Metal Matrix Diaphragm (MMD) technology permits you to hear recordings--perhaps for the first time--exactly the way the artist or director intended. What can prevent this from happening are resonances, unwanted colorations, or distortions, of the sound reproduced by a speaker; and every transducer has its own unavoidable set of reasonances based on its physical characteristics. The trick is to build a transducer where the natural resonances are either above or below its audible range. To get this done, Infinity engineers developed Metal Matrix Diaphragm (MMD) transducer material, a sandwich made up of layers of ceramic alumina (5% of the total thickness top and bottom) anodized to a metallic aluminum core (the remaining 90% of total thickness). Among the stiffest materials known, alumina and aluminum were chosen because sound moves through them faster than through conventional transducer materials and the MMD sandwich responds to electrical signals very rapidly without coloring the sound at all. MMD technology is derivative of a similar patented sandwich material used on Infinity's premium speakers. At Infinity, elimination of resonances is paramount, whether at the top of the line or at the entry level. When other manufacturers claim that their transducers are ceramically coated, it's merely a cosmetic surface treatment. The Primus 360 incorporates MMD transducer material because Infinity knows the listener will be able to hear the difference.

Performance and Quality Assured

Before ever putting a speaker into production, Infinity engineers analyze a number of critical parameters, including: frequency response, spatial averages, phase response, and nonlinear distortion. Also analyzed are: sound quality (timbre and bandwidth), spatial quality (how well the speakers spread out the sound), stereo imaging, the multichannel soundstage (how strong the sound image is in front, behind, and to the sides), and dynamic capabilities (sound quality for very loud and very quiet inputs). The Primus Series speaker you bring into your home has been subjected to some of the most rigorous analysis and testing in the industry, all to assure you superb performance and superior quality.

Decide For Yourself

In the final analysis only you, the listener, can judge the performance of any speaker. Infinity does all it can to make certain that your verdict will be a good one. They employ listeners with naturally acute hearing and then train them to express what they hear in ways that help engineers identify what's right and wrong about the speaker. Only after the Primus 360 was rated best-in-class against other manufacturer's comparable products, was it ready for production. Infinity's dedication to creating good sound in any room, anywhere in the room, is a benchmark in the loudspeaker industry. Invisible, uncolored, unchanged, natural sound, exactly as the musician or director meant for you to hear it--that's Infinity.
