Amazing Sound and Elegance

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.

Reference quality sound

Purity of Sound

X-Port

Reserve R400 features two X-Ports, featuring a set of closed-pipe resonators, called Eigentone filters that are tuned to absorb unwanted port and cabinet resonances, providing you pure, unadulterated, crystal clear sound and more bass output.

Form and Function

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.

Rated 5 out of 5 by from Great center channel Running as the center to a full Reserve theater. Currently in 5.1 but soon to be 7.2.4 driven by a SR8015. Very well balanced with plenty of head room to spare.

Rated 5 out of 5 by from An excellent large center channel I have this with a pair of R600s. Crystal clear highs and provides for strong dialog clarity. The center speaker is the most important in a home theater system. Although it's a large center channel speaker and has a wide and deep cabinet it's not too tall compared to others.

Questions

How much of an upgrade is this from my current CS10?

Asked by: Johnny Ray
Hello, the Polk Audio CS10 is still a formidable center channel. However, one should notice a significant upgrade when moving to the new R400 center channel. With its new driver technology, advanced Pinnacle ring radiator tweeter with an integrated waveguide, and upgraded crossover network, the R400 center speaker is the clear winner.

Is it's good to match r400 with S20 as LR ch?

Asked by: Nirmal
LIKE MOST POLK AUDIO SPEAKERS, the R400 and S20 will make for a fine match. However, I recommend pairing the S20 speakers with the ES30 center speaker or the R100 bookshelf speakers with the R400 center speaker for even better synergy.

How many inches should the R400 be away from the wall?

Asked by: Mark12
The rear-firing X-Port does provide some flexibility when it comes to placement. However, I recommend placing the R400 center speaker at least 4" away from the wall if possible.

Can the R400 be used as L and R like the R350 if stood on its side? Are the rubber feet removable?

Asked by: Vman
Theoretically, it can be used as an L/C/R but was purposely built as a center channel. I recommend using the R400 as a center channel and the R200 Bookshelf speakers as your Left and Right.

I just purchased the R400. Does Polk make a center channel stand - or recommend a manufacturer that has stands to match the size / color of the R400 in walnut? Thx

Asked by: Greg M
Hello, we currently do not offer speaker stands. However, Sanus speaker stands are often used and recommended. Finding a stand in Walnut may require a bit of research online. Here are a couple of links giving you an excellent place to start. - https://www.crutchfield.com/S-LPSMbFg2YP7/shopsearch/speaker_stands.html?XVINQ=MI2&XVVER=B78&awcr=77240710498910&awdv=c&awkw=walnut%20speaker%20stands&awmt=p&awnw=o&awat=&awug=78550&msclkid=6bd74c4d49461086d3e92fa7f6267c48&pg=2 - https://www.sanus.com/en_US/products/speaker-stands/nf24/

What should I set the crossover to?

Asked by: polkemon
Deciding on the final crossover setting depends on a few factors, listening preferences, room dimensions, room acoustics, and partnering speakers and subwoofer. 80Hz is a good starting point.

Is it okay to place the R400 on a shelf that is closed on the back, sides, and top with only 1 inch of clearance on each side and above? I was concerned if it needed more space due to the rear X-ports.

Asked by: Mickey
Hello, I will work in the environment you describe, but as there are ports on the rear of the R400, it is best to give it at least half an inch of space at back. Otherwise the low frequency information might sound a bit bloated.
Answered by: Polk Audio

How much weight can the R400 bear on top of it? I was hoping to place my TV (Sony x85x95k) directly on top of my center channel, and the TV weighs about 120 pounds.
