Product Description

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 speaker 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 P163BK 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 P163BK 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 bookshelf loudspeaker high frequency response
  • 6 1/2" (165mm) MMD low-frequency driver
  • 3/4" (19mm) MMD high-frequency driver
  • 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 P163BK'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.

    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.

    By using an acoustical waveguide, high frequencies have a wide dispersion throughout the room.
    To make sure listening to the Primus P163BK 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 P163BK 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 P163BK 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 P163BK's 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 P163BK, 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.

    I purchased a set of these speakers about a year ago to supplement my Cambridge Soundworks Movie Works surround speakers. I moved my old front speakers to the 7.1 top fronts and used the Infinity Primus as my new fronts. So far, I have been very impressed. The quality of sound has been superb. Since these are part of my existing system, I've already got a nice powered sub that takes care of the lows but these seem to do a great job through the whole octave range.

    I purchased the 6-1/2" but be aware that they are large and heavy and will take up a lot of real estate for front speakers - especially if you're used to satellite style speakers. They look very nice though - the front covers are nicely styled and the speakers really look nice with or without the screens.

    Compared to other fronts I've owned:

    * Bose 201's - Primus sound is superior in my opinion (muuch better range). Size and style of the Bose slightly superior.
    * Cambridge Soundworks MovieWorks 5.1 - Here again, Primus sound is cleaner and has better range. 3 x smaller than the Primus so there is a space sacrifice when owning this set.

    Overall, the build quality is great and the sound is great too. I'd highly recommend these for the price.

    I purchased the entire Infinity Primus series--2 front, 2 rear, and 12' sub--and am very pleased with the sound quality. It's amazing the difference rear speakers will make in the total sound image. These provide excellent mid-range and highs for viewing movies and TV. My only complaint is they're made in China...

    Build quality
    Dynamic range
    Overall sound quality
    Very good efficiency

    Extremely long break-in (mechanical run-in) period

    If there has ever been a speaker that needed a long break-in this is it (there is a very good article on mechanical run-in on the Wikipedia). Prospective buyers should be aware that these speakers do not sound particularly good out of the box. The drivers are made of metal (like your car) and ceramic (like your dishes) so much like the sound of dropping your dishes or crashing your car, they can be downright unpleasant at first.

    First, let's talk about the elephant in the room. Although largely ignored, the Primus speaker line has a 5 year warranty against manufacturer defects. Think about that for a second. Pretty much everyone else wants to sell you an extended warranty and most of those will only get you to three years. This product comes with a very long warranty and does so with a product that is already at bargain basement prices. I own both the Primus 150's and P152's and they have been trouble free for ten and eight years (respectively) although I did break the grill mounts on the P152's during a move. Clearly not a manufacturer defect but I digress. The enjoyment of music is not about warranties, so let's get to it.

    I got my Primus 150's back in 2004 and they have been my reference speaker ever since (not to say they are my best speakers but they are my baseline for comparing other speakers for sound quality). In 2006, I decided to get a second pair but they had been discontinued by that time and replaced by the Primus P152. Unfortunately, it turned out that newer was not better.

    I bought these speakers from Fry's at 59.99 each! I try to buy everything I can at Amazon but sometimes the prices just aren't right. Amazon prices fluctuate quickly sometimes.

    I added these speakers as my surround sound speakers, and wow what a difference! My fronts are the Infinity Primus 363, Polk sub, BIC America Center. I know it's a mish mash of speakers but does it ever sound great. The power comes from my Onkyo 809 bought at Amazon.

    I'm also using 2 Bose 301's for height. If these new speakers require a break in period, I can't imagine this will get better.

    I grew up in a time where great sound meant big tower speakers. Don't get me wrong I do love my towers. However, my wife is remodeling the room, and asked after all these years if we can finally move the hulking beasts out. Music should be heard, but the equipment shouldn't be an eyesore.
    I listened to a variety of bookshelf and built in speakers and these are the best in my opinion. The comparable Klipsch have a great high end (sizzling cymbals) but weren't as clear in the midrange. The comparable Polks were very warm and rich in the midrange, but lacking some at the high end. Both are great brands and have really excellent speakers. Do listen for yourself and decide which of these three fine brands you prefer. But for me, these Infinity's are ideal. They have great range from high to low, and are are so clear throughout the spectrum, that I only hear pure, uncolored music. Paired with a subwoofer, these are even better than my big tower speakers.
    I use these for my left and right speakers - for music and home theater. Visually, they blend right in, sitting on shelves on either side of the flat screen TV. My Infinity subwoofer is tucked away on the floor, near the screen too. Gone are the big ugly towers. These reproduce music wonderfully.
    Frankly, these sound better, or equivalent, to other "high end" brands that cost hundreds or even thousands more. If those others sounded superior, I would have bought them. These relatively inexpensive Infinity's are the way to go. They reproduce sound amazingly and are a steal at this price. I am very happy with my purchase.
