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.

Offers Complete Privacy
Color: Black, Size: 132in-Large Metal Base
We tried others that were nice but this particular room divider adds total privacy. We were looking for that. Easy to assemble. There is no gap if you position each petition close enough. The guality is very nice. Exactly what we were looking for.

Easy peasy
Size: 1 Panel, Color: Black
Bought this single-panel room divider for my son so he has a little privacy when he has to keep his camera on for online classes. It’s lightweight, easy to set up, and does the job—he can focus without me photobombing in the background. He can feel like he has his own tiny corner office, even if it’s just the basement.
