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.
