Product Description ------------------- Infinity Primus Two-way dual 5-1/4" floorstanding speaker Black (Each) From the Manufacturer --------------------- Incredible sound. Incredible price. ----------------------------------- Prepare to raise your expectations. Experience home entertainment at a new level of clarity and realism. From unobtrusive bookshelf systems to dazzlingly powerful home theaters, there's an Infinity Primus system that's right for every purpose and room in your home. Most other speaker systems in the Primus price range sound as if they are spraying their sound at you - tinny, hollow and reproduced - a copy of a copy. With its MMD transducer technology and seamless component architecture working in unison to eliminate unwanted resonance modes, the Primus P253BK doesn't spray - it immerses, rolling over the listener with warm, rich sound the way live music does. Pair it with any one of our powerful MMD-equipped floorstanding loudspeakers, subwoofers, and center-channel speakers, and the Infinity Primus P253BK will fill any room with dramatic and well-defined sound. This is where Infinity sound begins, and it's well within your reach. * Two-way floorstanding loudspeaker * Dual 5-1/4" (133mm) MMD low-frequency drivers * 3/4" (19mm) MMD high-frequency driver * Five-way binding posts * Legendary Infinity engineering - speaker components seamlessly work together as an integrated system * Extremely low resonance enclosures - hear music exactly as it was recorded * Tweeter waveguides improve on-and-off-axis high-frequency response * Precision crossover networks * Patented MMD transducers significantly improve cone performance, providing ideal rigidity and resistance to precision sound across the entire spectrum The P253BK's tweeter delivers crystal clear high frequencies. 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. The patented MMD material's sandwich design makes the driver incredibly strong and lightweight.

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. By using an acoustical waveguide, high frequencies have a wide dispersion throughout the room. To make sure listening to the Primus P253BK 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 P253BK 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 that it plays. To eliminate any enclosure resonance from the P253BK 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 P253BK, 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.
