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
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.
5-Way Binding Posts: The 5-way binding posts will accept
bare wire, pin connectors, spade connectors, banana plugs, and dual banana
Color-Coded: The speaker's binding posts are color-coded
(red/black) for easy identification between positive and negative.
Rubber Feet: The speakers come with 4 rubber self-adhesive
feet for each speaker to help secure them in place to prevent slippage and
Wall Mounting: The optional PinPoint heavy duty
side-grip wall-mounting bracket (121AM40B,
sold separately) can be used to wall mount the speakers.
