Know before you buy
The R400 is a dedicated center channel speaker designed to anchor your home theater system. Its primary role is to handle dialogue and mid-range frequencies, ensuring voices remain clear and intelligible even during complex action scenes.
The R400 is a passive speaker, meaning it requires an external amplifier or an AV receiver to function. With an impedance of 4 Ohms and a power handling capacity of 200 Watts, ensure your receiver is capable of driving 4-Ohm loads for optimal performance.
Polk's patented X-Port technology is designed to eliminate unwanted cabinet resonance and port noise. By cleaning up the airflow, it ensures that the bass and mid-range frequencies sound tighter and more accurate without distortion.
Yes, the R400 is well-suited for larger spaces thanks to its dual 6.5-inch Turbine cones and high power handling. Its design creates a broad 'sweet spot,' which helps maintain consistent audio quality for viewers sitting in different positions across the room.
Hi-Res Audio certification indicates that the speaker is capable of reproducing the full, extended frequency range of high-resolution audio files. This allows you to hear more detail and nuance in your music and movie soundtracks compared to standard audio formats.
The R400 measures 7.8 inches high, 24.2 inches wide, and 13.8 inches deep. Given its weight of 32.8 pounds, ensure your media console or shelf is sturdy enough to support the speaker and has enough depth to accommodate its 13.8-inch footprint.
