Music and Movies as they were meant to be heard.

Patented MMD transducer technology improves sonic accuracy

Derived from our patented CMMD technology, the Metal Matrix Diaphragm (MMD) approach continues the Infinity tradition of using advanced materials to improve sonic accuracy. These diaphragms are much stiffer than standard metal ones – by anodizing both sides of an aluminum core, we’re able to significantly improve cone performance and outperform cones made of paper, polypropylene or Kevlar material.

Acoustical waveguides deliver wide high-frequency response

Where you sit in a room as you listen to speakers can have just as great an effect on their sound quality as the speakers themselves.

To make sure listening to the Primus P143 s truly a great experience everywhere in the room, they use a proprietary “waveguide” around the tweeter. This waveguide ensures a wide dispersion of the high frequencies throughout the room while keeping them both accurate and natural-sounding. The result is an enveloping, realistic sound experience throughout the entire room, making the P143 perfect for critical music and movie reproduction.

Low-Resonance enclosures do not change or alter the sound

A great sounding loudspeaker should play just what it’s told to without changing or altering the sound. One way that a poorly designed loudspeaker can change the sound is when the enclosure resonates or vibrates. Resonance can change a speaker’s overall tonal balance and totally alter the sound of the recording that it plays. To eliminate any enclosure resonance from the P143 bookshelf speakers, Infinity engineers the enclosure using pinpoint internal bracing that increases rigidity so it does not vibrate or resonate. Bass sounds tight and accurate while the soundstage is smooth and precise. Plus there’s the added advantage of a sleek, narrow enclosure that’s at home in nearly any room decor.

Superior Infinity engineering delivers sound perfection

Many loudspeaker manufacturers are actually loudspeaker assemblers, buying parts off the shelf from different companies with the goal of assembling them into a final product. While this might help keep costs down, it gives very little guarantee about how the speakers are going to sound. The Infinity Primus P143 speaker drivers, baffles, cabinets and waveguides are all designed and engineered by Infinity to work seamlessly together as an integrated system, fitting together like pieces of a jigsaw puzzle. And since Infinity has engineered each piece for the best possible sound quality, the result is a loudspeaker that we can guarantee will dazzle you no matter what you happen to be listening to.

Infinity – Legendary reputation. Uncompromising craftsmanship and sound.

With the Infinity Primus P143, you not only experience the cutting edge in high-performance transducer technology and sound reproduction, you experience the cutting edge from the makers of Infinity products – some of the world’s most innovative, high-quality audio equipment. The road to the Infinity Primus series is a road lined with dozens of audio milestones: The Infinity Servo Statik 1a – the world’s first powered subwoofer. The EMIT (Electromagnetic Induction Tweeter) device. The revolutionary IRS speaker – the world’s first “reference” loudspeaker. The Prelude MTS speaker – the world’s first powered tower speaker. Since 1968, innovative Infinity technologies, materials and manufacturing techniques have advanced the science of sound, and have set new standards in loudspeaker technology and performance. Infinity Primus Series speakers benefit from every Infinity innovation that has come before. This is where Infinity sound begins, and it’s well within your reach.
