Polk Audio Reserve R400 Center Speaker

Polk Audio Reserve R400 Center Speaker

Polk Audio Reserve R400 uses two 6.5-inch Turbine bass/midrange drivers.

This driver configuration supports clear dialogue reproduction in larger home theater systems. Place the speaker on a suitable support below or above the television.

The Pinnacle Ring Radiator tweeter uses a waveguide to control dispersion and widen the listening area. Turbine Cone geometry increases cone stiffness without adding mass, helping the driver follow changes in the signal accurately.

X-Port uses tuned resonators to suppress unwanted cabinet and port resonances, reducing bass distortion while preserving midrange clarity.

Main Features

• The removable magnetic grilles offer a choice of covered or exposed drivers.
• Nickel-plated 5-way binding posts accept bare speaker wire, spade connectors or banana plugs.
• An external amplifier is required. A home theater amplifier performs Dolby Atmos and DTS:X decoding.
• Hi-Res Audio certification and an overall response extending to 50 kHz support high-resolution audio playback.
• Choose from black and walnut finishes using the product color selector.
• Rounded cabinet edges reduce diffraction and help maintain even sound dispersion.
