Infinity Primus PC351

Three-way center-channel loudspeaker, Dual 5.25", 80 Hz - 20 kHz, 8 Ω, 91 dB, 11.4 kg, Black wood-grain The Infinity Primus® Series – Where Infinity sound begins.
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 Infinity Primus PC351BK doesn’t spray – it immerses, rolling over the listener with warm, rich sound – the way live music does. Combine the Primus PC351BK with any one of our powerful MMD-equipped floorstanding loudspeakers, subwoofers, and bookshelf speakers, and the Primus PC351BK will fill any room with dramatic and well-defined sound. This is where Infinity sound begins, and it’s well within your reach.

The Infinity Primus® PC351BK - A solid center.
A well-designed center-channel speaker ensures a listener can clearly hear song lyrics or dialogue above the bombast and bassy low frequencies. The Primus PC351BK splits audio signals from the receiver among five different loudspeakers. Low frequencies are sent to dual 5.25-inch Metal Matrix Diaphragm™ (MMD) woofers. Dual 3-inch MMD® midrange drivers handle the middle frequencies, allowing the tweeter and the woofer to produce sparkle in the high frequencies and boom in the low frequencies, without interruption or interference. Boasting a high crossover frequency of 2,800Hz and a low crossover of 650Hz, the Primus PC351BK reduces strain on the respective speaker drivers, allowing them to independently focus on their respective ranges.

Incredible sound. Incredible price.
With their excellent midrange clarity and three-way capabilities, the Infinity Primus® PC351BK is the perfect home theater companion. Dialogue and foley tracks are articulated exceptionally well and seem to hang in the air - even amidst the most cacophonic battle or chase scene (or Hans Zimmer score). The Primus PC351BK brings long-term, plug-and-play, trouble-free enjoyment to home theater, unheard of at this price point - and it is the perfect complement to any 5.1 or 7.1 channel home theater system.

Patented MMD® transducer technology.
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, 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.

Superior Infinity® engineering.
The Infinity Primus® PC351BK's speaker drivers, baffles, cabinets and waveguides are designed to work seamlessly together as an integrated system - fitting together like pieces of a jigsaw puzzle. It begins with our ultra-precise transducers - the beating heart of the Primus PC351BK. MMD® technology doesn't change, color or distort audio signal sound the way diaphragms made of other materials do. This combines with the Primus speaker's low resonance enclosures to compound the precision qualities of the transducer, further eliminating mechanical distortion.

Infinity - Legendary reputation. Uncompromising craftsmanship and sound.
With the Infinity Primus® PC351BK, 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.
