Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Our take on the Infinity Primus P163

by Kristen Schaub

With Infinity's Primus P163, you get the real deal — rich, detailed sound and a price tag that won't leave your wallet empty. It's all thanks to a combination of Metal Matrix Diaphragm® driver technology and a low-resonance enclosure. You'll hear sparkling high frequencies and detailed midrange from any type of music, at any volume level. And for a compact bookshelf speaker, the bass might just surprise you. So sit back, relax, and enjoy the lifelike vocals and robust instrumentals that this speaker has to offer.

Exclusive Infinity Metal Matrix Diaphragm drivers
The Primus P163 features Infinity's exclusive Metal Matrix Diaphragm ("MMD" for short) driver technology in both the 3/4" tweeter and 6-1/2" woofer. These MMD drivers consist of a stiff aluminum core, anodized on both sides for increased strength and rigidity. The result is extremely fast, extremely accurate response, so you'll hear distinctly cleaner, more realistic sound, even at higher volume levels.

Build a complete Primus® system
The Infinity Primus P163 will fill just about any room with dramatic and well-defined sound. Use a pair to create a high-quality stereo system, or add it to Infinity's P363 floor-standing speaker and PC351 center channel speaker to create a stunning Primus home theater system. And don't forget to add the perfectly matched PS38 powered subwoofer to get deep, accurate bass in the mix.

    Driver Technology

    Metal Matrix Diaphragm (M.M.D.): Derived from the C.M.M.D. material used in Infinity's flagship Cascade series, M.M.D. features a stiff aluminum core, anodized on both sides for increased strength and rigidity. M.M.D. transducers conduct sound faster than paper, polypropylene, and Kevlar, pushing unwanted resonances beyond the operating range of the transducer. M.M.D. drivers deliver crystal-clear, distortion-free sound from dynamic digital sources, even at high listening levels.

    6-1/2" Woofer: The 6-1/2" M.M.D. cone woofer offers extremely accurate midrange response for cleaner, more realistic sound. For a smoother response and improved durability, the woofer uses rubber surrounds.

    3/4" Tweeter: The speaker has a 3/4" M.M.D. dome tweeter that offers superior stiffness and damping compared to traditional metal domes.

    Acoustical Waveguide: The P163's tweeter utilizes an acoustical waveguide to deliver, more even high frequency response, no matter what part of the room you're in.

    Precision Crossover Network: The speaker features a 2-way crossover system with crossover frequency at 3000Hz. The crossover has a 24dB/octave slope.

    Voice-Matched: The P163 is voice-matched to all the speakers in the Primus line, so a complete matching system can be built.

    Magnetically Shielded: The Infinity Primus bookshelf loudspeaker is magnetically shielded for safe placement adjacent to your television.

    Enclosure Design

    Wood Grain Vinyl Cabinet: The Infinity P163 features a black wood grain vinyl cabinet that matches almost any decor.

    Bass Reflex Design: The Infinity Primus bookshelf loudspeaker utilizes a bass reflex enclosure with a front-firing port for greater efficiency and bigger bass response.

    Low Resonance Enclosure: The P163 employs a extremely low resonance enclosure, so you hear the music exactly as it was recorded.

    Grille: The speaker comes with a removable black cloth grille with a rigid plastic frame.

    Connections

    5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.

    Color-Coded: The speaker's binding posts are color-coded (red/black) for easy identification between positive and negative.

    Mounting Options

    Rubber Feet: The speakers come with 4 rubber self-adhesive feet for each speaker to help secure them in place to prevent slippage and vibration.

    Wall Mounting: The optional PinPoint heavy duty side-grip wall-mounting bracket (121AM40B, sold separately) can be used to wall mount the speakers.

    Sound as they sould, like speakers. I have not "let'um loose" to see what they can handle, but work very well as my front surrounds. Hoped for a richer bass, but as others say they will soften up and pitch down a bit.
    Pros:
    great size, great sound

    Infinity Primus P163 "Best bang for the buck!"

    Written By majog, Northern NY on Thursday, May 30, 2013
    Crutchfield Customer Review (What's this?)
     
    These speakers are amazing. Crisp clear tones from both lesser receivers and higher end amps. I had an older blown speaker that was pretty middle of the road. What a difference they made when I replaced them. Even when the amp is cranked up there is only minimal distortion and when I am out in the yard can enjoy music from my living room with the windows open. On my upstairs surround receiver they rock a movie. Liked them so well I bought 2 more.
    Pros:
    small, crisp clear sound, easy to connect, excellent value
    Cons:
    a bit heavy for their size (could be a plus), need to be off the floor for maximum effect and sound quality.

    Primus P163's

    Written By Beastn, St Louis, MO on Saturday, May 11, 2013
    Crutchfield Customer Review (What's this?)
     
    I have a 7.2 setup consisting of all Primus speakers. I recently replaced the P163's with the P363's towers as mains. If your game is listening to 2 channel stereo go with the 363's. They're a full range tower and deliver the lower frequencies the P163's cannot. However, if you have a quality sub go with the P163's! You can purchase 4 of these badboys cheaper than a pair of 363's. Pair 4 of these with the PC351 center and a sub and you will have a quality 5.1 setup. I'm currently using the P163's as surrounds and they are great fit in that position as well.

    *Note My P363's are not broken in yet so I may hear a distinct improvement in the future over the P163's. However, since I have the 80hz and below frequencies being handled by my subs I doubt that will be the case.

    Other info (equipment): Yamaha RX-A810 receiver, Velodyne SPL-1000. Klipsch RW-12, Primus P143's as surround backs.
    Pros:
    Excellent sound for the money
    Cons:
    Not wall mountable.

    A nice little speaker to go with my little 2.1 set up (Denon AVR-1913 and Infinity PS38 powered sub. The speakers play the sounds clearly and don't get distorted if I crank up the volume. Picked them up on sale for something like $85 each. Well worth it IMHO.
    Pros:
    Prices and clairity

    When paired with my Polk subwoofer I am experiencing great sound and clarity. I upgraded from some old Kenwood 3-ways and can't be happier. For the money, these were a great buy. Very satisfied!
    Pros:
    Great bang for the buck. Clean, powerful sound. Great for my small room.

    Great Speakers

    Written By The Classicist, Denver, CO on Sunday, April 14, 2013
    Crutchfield Customer Review (What's this?)
     
    Great speakers at a great price. As a classical music fan, I was looking for speakers with clarity and detail, and these really exceeded my expectations. A real upgrade in sound at a very reasonable price.
    Pros:
    Great sound at a great price. You can spend far more but for a modest sound system these are can't miss speakers.
    Cons:
    Bigger than I expected for a bookshelf speaker.

    Primus P163 Bookshelf speakers

    Written By Kathy S, Milwaukee, Wi on Wednesday, March 20, 2013
    Crutchfield Customer Review (What's this?)
     
    Just received my speakers yesterday - I am blown away by the sound these bookshelf size speakers put out. I'm a bass lover so I tested them out with some 70's Santana. I was ECSTATIC to find out they performed almost as well as my tower speakers and I actually had some bass to spare. Sound is clean and full. I would recommend these speakers to anyone wanting big speaker quality in a smaller, lighter package.
    Pros:
    Full sound with more than adequate bass. Not "tinny" sounding like a lot of bookshelf speakers I've heard.
    Cons:
    Pretty tall for a "bookshelf". I have them on matching wooden plant stands that I was going to give away - glad I didn't

    Written By Dave/the painter., Lafayette, CO. on Tuesday, January 15, 2013
    Crutchfield Customer Review (What's this?)
     
    Initially these were very bright and, for me, can dominate a bit instead of fitting in. However, over time I found they mellow out and soon take their place providing beautiful music or wonderful dialogue, sound or effects when watching movies. I look forward to many years of enjoyment with these cabinets.
    Pros:
    Nice price for the quality of speaker system involved.
    Cons:
    None so far.

    Nice speakers with great sound. These are used mostly for music connected off an older Kenwood receiver in a sun room 12x14. They really crank and the music is nice and clear. I would highly reccomend them and the price is very afforadable. Of course great customer service from Crutchfield as always!!!

    Great bang for the buck

    Written By Mike, Dallas, TX on Wednesday, December 12, 2012
    Crutchfield Customer Review (What's this?)
     
    Got these on sale for $172 for the pair delivered. I had bought the matching center channel speaker several months ago and it was time to replace the aging bookshelf speakers with 12" woofers. I was concerned about loosing those big woofers, but with a sub woofer it's not a problem. Tighter, brighter sound than the old speakers. Some people complain that these are overly bright, especially at high volumes. I'm older and have experienced some high end hearing loss, so the extra hi end is welcome. For others, it's a simple matter to attenuate the hi's, but you can't manufacture them if they are not there to begin with.
    Pros:
    Good clear sound and plenty of it (93dB sensitivity). Are they an audiofiles dream? No, But they sound WAY better than you would expect at this price. Infiniti makes a great bang for the buck speaker.
    Cons:
    None

    They came quickly, carefully packed, and very easy to set up. They were a bit larger than I imagined, although they were the size advertized. They have a good clear sound and they are plenty loud enough. They're built well and look sharp. I'm very happy with them.
    Pros:
    great sound
    Cons:
    a bit larger and bulkier than I might have liked.
