Our Product Research Team
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.
We stay on top of new products and technologies to help people make informed choices.

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.
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.
3/4" Tweeter: The center channel speaker has a
3/4" M.M.D. dome tweeter that offers superior stiffness and damping
compared to traditional metal domes.
Acoustical Waveguide: The PC251'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: The center channel speaker
features a 2-way crossover system with crossover frequency at 3000Hz. The crossover has a 24dB/octave slope.
Matching System: The PC251 is voice-matched to all the speakers in the Primus line, so a complete
matching system can be built.
Magnetically Shielded: The Infinity Primus center channel
loudspeaker is magnetically shielded for safe placement adjacent to your
television.
Enclosure Design
Wood Grain Vinyl Cabinet: The Infinity PC251 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 performance.
Low Resonance Enclosure: The PC251 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
Wall Mounting: The center channel speaker has
two keyhole slots in the upper left and right corners of the back panel. In
addition, two non-skid rubber bumpers are attached in the lower corners so the
speaker won't mar wall surfaces when the speaker is mounted.
