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.

Monitor stand that stands up!
Color: White
This monitor stand is absolutely perfect. It gives back inches of desk space and provides additional storage with the shelves and 2 small drawers. Assembly was simple and the stand is sturdy and looks great. The profile is low enough that your monitors are not too high up from your laptop/keyboard. Definitely a game changes for the home office!

Great Monitor Riser/Stand!
Color: Oak, Color: Oak
I’m so happy with the way it turned out!! Easy assembly in about 15 min. It’s so cute and you can customize if you’d like the drawers to be on the left or right side. I just noticed a slight deviation in material dimensions so it looks a little off. But it’s still functional!

high quality and sturdy !
Color: Brown, Color: Brown
if you’re thinking about it, get it! i splurged to get this, but it’s so nice. it’s high quality and sturdy, plus it helps a lot to organize and keep things neat. putting it together was just like an ikea item and took much longer than i thought- around ~30-45 minutes, but it was worth it. i wanted a stand that would be able to fit my 2 monitors, and this is perfect. i’ve had it for over 6 months now and it still looks brand new! it really upgrades your desk space and makes it feel nicer. 10/10 recommend

Does Everything and More
Color: Oak
This stand allows me to raise my large monitor. It also gives me storage space for my sound bar, laptop, pillcase and more! I place my keyboard and mouse pad on the lowest portion of the stand when not in use. I like the two drawers on the side. I also like that there is room for a light and pencil case holder to the right of it. I had a real problem organizing my stuff on my desk but now I have a location for everything. I survived without it for so long, but now that I have the stand, I am really please with the set up. The only down side to having this with a large monitor is that it will block out a window completely. I had to buy a gaming light and install it from behind to give light to the front of the desk. Now my desk is fabulous. Great product but make sure that your desk is large enough to house this monitor riser as it is large. It does go on sale occasionally. So you can put a watch on the stand and purchase it when the price drops.
