At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.

Metal Matrix Diaphragm
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.
5-1/4" Woofers: The dual 5-1/4" M.M.D. cone woofers offer extremely
accurate lower midrange response for cleaner, more realistic sound. For a
smoother response and improved durability, the woofers use rubber surrounds.
3" Midranges: The PC351 has dual 3" M.M.D. cone midranges for
full, accurate upper midrange sounds. The mids also use 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 PC351'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 3-way crossover system
with crossover frequencies at 650Hz and 2800Hz. The crossover has a 24dB/octave
Matching System: The PC351 is voice-matched to all the
speakers in the Primus line, so a complete matching system can be built.
Wood Grain Vinyl Cabinet: The Infinity PC351 features a
black wood grain vinyl cabinet that matches almost any decor.
Acoustic Suspension Design: The Infinity center channel
utilizes an acoustic suspension (sealed) enclosure for tight, accurate midbass
Low Resonance Enclosure: The PC351 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.
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.
