About the Infinity Primus P163
A dual purpose workhorse for music and home theater
The Primus P163 delivers rich, full sound without taking up too much space.
High quality materials for long term performance
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.Product highlights:

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.

For the price these speakers are a steal. They are nearly full range and pretty powerful for such a small package. How is Infinity not losing money on these? They compare sonically to speakers costing ten times as much, such as those by PSB, Revel, Paradigm, Thiel, and others.
