Affordable Technology, Performance, And Style

With the newly restyled Primus Series, 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. First, listen to the sound produced by the Primus P152's 5.25" woofer 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 P152. You'll be struck by the modesty of a purely functional design with refined, contemporary styling that imparts an elegant, understated appearance. Their rich black-ash-finish enclosures are accented by attractive light-silver grilles that have gracefully curved and tapered top surfaces. With the grilles off, the speakers present a striking, high-tech look, with metallic-silver drivers mounted in matching bezels. All of this, allied with Infinity's tradition of excellence in sound reproduction, makes the cost of this speaker all the more amazing.

The MMD Performance Payoff

All Primus Series loudspeakers incorporate Infinity's proven MMD (Metal Matrix Diaphragm) technology to provide superlative sound quality. MMD driver cones are manufactured by anodizing both sides of an aluminum core to a controlled thickness, producing low-mass, highly rigid driver diaphragms that operate with greatly reduced distortion, and deliver extraordinary transient response, resolution, and smoothness throughout their entire frequency range. Each tweeter, midrange, and woofer is optimized for its particular application, with internal resonances virtually eliminated within each driver's frequency range to achieve maximum sonic clarity. The result is richly detailed, expansive, and dynamic sound, with articulate bass, musically accurate midrange, extended high frequencies, and exceptionally realistic vocal and instrumental reproduction.

Hear What You've Been Missing--How MMD Works

Infinity's 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 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 P152 incorporates MMD transducer material because Infinity knows you'll be able to hear the difference.

More Tests Than A High School Math Class

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 testing and analysis in the industry, all to assure you superb performance and superior quality.

No Matter Your Lifestyle, The Primus Series Will Fit

In common with all Infinity loudspeakers, Primus Series models are designed utilizing the company's room-friendly design principles, which ensure they will provide sonically accurate performance in the widest variety of listening environments and placement positions. All tweeters are mounted in a specially shaped, recessed waveguide that provides precise imaging, even frequency response and controlled directivity over a wide listening area, creating an immersive multichannel or stereo listening environment. All models feature high sensitivity to deliver satisfying volume levels and wide dynamic range even when using lower-powered receivers. All are built to Infinity's high quality standards featuring rigidly braced enclosures for minimizing unwanted internal resonances, crossover components selected for best sound quality; magnetic shielding, and many additional refinements. Primus Series loudspeakers are ideal for a wide variety of home entertainment requirements, from compact home theater and music systems to larger home entertainment installations where expansive, authoritative, large scale playback of movie soundtracks and music is desired.
