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.

By virtue of its extreme rigidity and resistance to resonance, the MMD material is far more than just another diaphragm substance. It is an ideal diaphragm material for the ultimate listening experience. Sound propagates at a higher velocity in metals than in materials such as polymers and papers. Sound will travel through MMD material nearly twice as fast as it will through any other cone material – thus, moving unwanted resonances outside the audible range.

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 P253 is 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 P253 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 P253 tower loudspeakers, 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

With the Infinity Primus P253, 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.
