The R400 offers unrivalled power and clarity from a centre channel speaker. The addition of two 6.5” turbine cone woofers and Polk’s unique X-Port technology means it delivers enormous yet balanced sound, ideal for the ultimate home theatre system.

Key Benefits

  • Patent pending X-Port
  • Unrivalled power and clarity
  • Blends into any décor
  • Sleek and elegant design

 

Power And Clarity

As we get older, we learn what better looks like, feels like, tastes like, and even drives like. Inheriting best-in-class technologies from our flagship Legend series of loudspeakers, the Polk Reserve series helps teach you what better sounds like.

Crystal Clear Vocals For Home Theatre

The centre channel is the most important speaker in any home theatre setup. The Reserve R400 uses Polk’s latest flagship transducer array to deliver clear, crisp, intelligible dialogue no matter where you sit.

Pinnacle Ring Radiator Tweeter

The Pinnacle Ring Radiator Tweeter’s distinctive pointed shape guides the dispersion of high frequency sounds around a room. This innovation widens the sweet spot and allows you freedom to enjoy your music and movies wherever you choose to sit.

Turbine Cone Woofer

Our pioneering turbine design delivers a significant increase in cone rigidity without increasing mass. This innovation means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution, enabling you to experience a breathtaking level of detail in your music and movies.

 X-Port

Polk's proprietary X-Port eliminates unwanted noise created as air moves in and out of the speaker cabinet port at high-speeds. This ensures a rich and detailed listening experience with tight distortion-free bass and a clean midrange.

Exceptional Cabinetry

Reserve’s sleek cabinetry hides a world of audio innovation. Cabinets are carefully cross-braced to best eliminate unwanted interior resonances. Rounded exterior corners help disperse sound broadly around the room with minimal diffraction, creating an open sound stage.

Hi-Res Audio Certified

The Reserve Series sets the benchmark for music and movie audio excellence.

Nice room divider!
Color: White, Size: 8 Panel
The white panels are a nice off-white color. shipped in perfect condition. Already assembled so set up was quick. We use them to separate a photo studio from the main entry. Easily covers a 6 Ft. opening to the room. They are a woven material with wood colored sticks to support the weave. They are about 6 Ft. tall at the top of the curved section but less at the hinged sections. Light and easy to set up and take down. We are straddling two different floors so the extended legs at the bottom make this easy. Not sure how to clean them but they look great so far!

Instant Privacy
Color: Beige, Size: 8 Panel
Bought this to separate a ground level living area used as an office. Works well to cover visual clutter; allows a clean look when entering the front door. Comes fully assembled. Hinges are sturdy enough, as long as the panels aren’t stretched too far; have to allow some bend between them. For the price point, quality and functionality are satisfactory.

Great Divider, Just Needed Anchoring for Outdoor Use
Color: Grey, Size: 6 Panel
This room divider is very nice—stylish, lightweight, and easy to set up. I’m using it outdoors, which may not be its intended use, and I found that wind can knock it over pretty easily. Once I anchored it down, though, it worked just fine and looks great in the space. Indoors, I imagine it would be perfect right out of the box. Overall, a solid purchase with just one small adjustment needed for my setup.

Good Quality
Color: White, Size: 4 Panel
They are made with good quality. However I bought them to help with blocking outside light and the white does not do that.

Very nice looking divider. We are using as a privacy divider around our hot tub. We have not left it out in the weather yet due to many storms coming through.
