High quality materials for long term performance
The Primus PC251 features Infinity's exclusive Metal Matrix Diaphragm ("MMD" for short) driver technology in both the 3/4" tweeter and the dual 5-1/4" woofers. 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, giving you distinctly cleaner, more realistic sound, even at higher volume levels.

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.

Installed this replacing my old much smaller center speaker. This new speaker makes movies at TV shows come alive. This speaker puts out clear sound, and a lot of it. Makes voices so much clearer, sounds great...... Pairs well with my built in wall speakers, brand unknown....
