The Polk Audio Reserve R400 Center Channel Speaker is engineered to deliver exceptional dialogue clarity, powerful dynamics, and reference-grade cinematic performance for premium home theater systems. Incorporating technologies derived from Polk's flagship Legend Series, the R400 creates a wide, immersive soundstage with crystal-clear vocals, making it the ideal centerpiece for Dolby Atmos and DTS:X surround sound setups.

At its core is Polk's renowned 1-inch Pinnacle Ring Radiator Tweeter, designed to extend high-frequency performance up to 50 kHz while maintaining smooth, detailed, and fatigue-free listening. Complementing the tweeter are dual 6.5-inch Turbine Cone woofers, engineered with increased cone rigidity to minimize distortion and reproduce highly accurate midrange and bass frequencies with exceptional control.

The Reserve R400 also features Polk's exclusive Dual Rear X-Port technology, utilizing Eigentone filters to eliminate unwanted port and cabinet resonances. This advanced bass-loading system delivers cleaner, deeper bass with reduced turbulence, allowing movie soundtracks and musical performances to maintain impressive impact without compromising vocal clarity.

Supporting Hi-Res Audio, IMAX Enhanced, Dolby Atmos, and DTS:X, the Reserve R400 seamlessly integrates into modern high-performance home theater systems. Its rigid, internally braced cabinet with rounded edges minimizes diffraction while preserving accurate imaging across a wider listening area. Compatible with 4Ω, 6Ω, and 8Ω amplifiers, and capable of handling up to 200 watts, the R400 offers outstanding performance in medium to large home theaters. Whether paired with Polk Reserve floorstanding or bookshelf speakers, the Reserve R400 delivers a remarkably natural and immersive cinematic experience.
