Polk R400C – Premium High-Performance Center Channel Speaker
The Polk R400C brings cinematic precision and crystal-clear dialogue to your home theater. Designed for movie lovers and audiophiles, this high-performance center speaker delivers unmatched realism. Every line, whisper, and sound effect is projected with detail and warmth, making you feel part of the story.
Part of Polk’s Reserve Series, the R400C combines modern design, advanced technology, and acoustic engineering for true-to-life performance.
Design & Build Quality of the Polk R400C
The Polk R400C reflects the brand’s signature blend of craftsmanship and functionality. Its rigid MDF cabinet and internal bracing reduce unwanted resonance, ensuring clean and controlled audio. The matte black finish and magnetic grille give it a refined appearance that blends easily into any living room or media setup.
Thanks to its aerodynamic front baffle and horizontal layout, the R400C provides wide sound dispersion. You’ll enjoy consistent clarity across the entire seating area, not just the center sweet spot. This thoughtful engineering guarantees that both looks and sound work together in harmony.
Power Output & Performance
Built for performance, the Polk R400C features dual 6.5” Turbine Cone midrange drivers and a 1” Pinnacle Ring Radiator tweeter. The combination delivers lifelike sound and powerful presence.
The Turbine Cones are designed with Polk’s patented core structure, improving stiffness and damping for natural midrange reproduction. The Pinnacle tweeter, tuned for high-frequency precision, extends treble response up to 40kHz. Together, they create a balanced, distortion-free soundstage with detailed vocals and strong dynamics.
With a frequency response of 48Hz–50kHz and 89dB sensitivity, the R400C easily handles demanding movie tracks or orchestral soundscapes. Whether you’re watching a quiet drama or an action-packed blockbuster, the Polk R400C keeps every sound crisp and immersive.
