A trio of balanced drivers provide crisp, clear dialogue for TV and movies.
High quality materials for long term performance
The Primus PC351 features Infinity's exclusive Metal Matrix Diaphragm ("MMD" for short) driver technology in the 3/4" tweeter, both 3" midranges, and both the 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 — you'll hear 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" 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 slope.
Matching System: The PC351 is voice-matched to all the speakers in the Primus line, so a complete matching system can be built.
Enclosure Design
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 performance.
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.
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.

This is the best CCS I have ever owned. Sounds better than my Polk CS-20 and Klipsch RC-62. Have it matched up with the Primus P363's up front and P163's for rears. Sub is PS312. Voices are crystal clear. I can hear everything, including background sounds I have never heard before.
