Get stereo sound from a single speaker

Looking to add music in tight spaces as part of your custom-installed home audio system? The RC6s in-ceiling speaker from Polk Audio delivers both channels of a stereo signal from a single overhead location. It's perfect for a bathroom, kitchen, hallway, or anywhere else that you want great stereo sound from just one hideaway speaker.

Polk Audio RC6s stereo-input speaker

Polk's dual-tweeter design reproduces both the left and right channels of your stereo music sources with a single speaker.

It's also great for big rooms

Want to jam to music in a big living room or bedroom? Place an RC6s in each corner and get stereo sound no matter where you are.

Its clever design gives you the full song without worrying about being too close to one speaker, and too far from another. That way you aren't hearing the guitar and vocals from the left speaker, and bass and drums from the right. 

Get all of the musical detail

Polk knows how important it is to preserve the high-frequency detail in your favorite recordings. So they've equipped the RC6s with two soft dome tweeters for crisp, clear sound.

They're paired with a robust 6-1/2" dual-voice coil woofer that takes care of mids and lows. On the back of the speaker you'll find separate connections for the left and right channels of your amplifier. 

DIY installation

Polk's rotating-cam design makes your in-ceiling installation go smoother. Once you have the RC6s in place, simply use a screwdriver to tighten each cam for a secure grip against the back of the ceiling.

If this is a do-it-yourself installation, check out our guide to installing in-ceiling speakers, along with our selection of in-wall speaker wire. An optional pre-construction bracket is recommended for new construction. Free lifetime technical support is provided with every Crutchfield purchase.

Product Research


Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Woofers: The RC6s features a Dynamic Balance, mineral-filled polypropylene woofer for clean midrange and deep, accurate bass. For a smoother response and improved durability, the woofer uses a rubber surround.

Tweeters: The speaker uses two 3/4" Dynamic Balance, metalized soft dome tweeters for smooth, accurate highs.

Stereo Sound: The dual tweeters in a stereo faceplate deliver left and right channel highs, while a dual voice coil driver automatically sums left and right channel mids and bass, giving you lifelike stereo imaging.

Infinite Baffle Tuning: Infinite Baffle Tuning uses the virtual enclosure of in-wall space for superior bass response.

Moisture-resistant: Durable, moisture-resistant materials allow you to install the speaker in bathrooms, kitchens, even under the eaves of an enclosed porch. (The speaker is not recommended for exposed outdoor use.)

Installation: The round shape and flush-design allow the RC6s to mimic the look of a recessed lighting fixture. The speaker requires a cutout of 7.563" and a mounting depth of 2.625". The speaker frame has a diameter of 8.907". Once the hole is cut, the speaker can be dropped in and the Rotating Cams can be tightened, allowing you to secure the speaker to the drywall without any extra assembly (the Rotating Cams protrude out 0.625" from the cutout opening).

Paintable: The grille and flange can be painted, allowing this speaker to match any decor.

Frequency Response:

  • Overall: 40 Hz-20 kHz
  • -3 dB Limit: 55 Hz-20 kHz

Three years ago we used this particular speaker system in our living room, kitchen and office and the sound was great. We are now remodeling a kitchen/dining room area and decided to add one more speaker to the dining room. Could not be more pleased with the Polk Audio RC6s in-ceiling stereo input speakers. For the money, the sound is clear, no tinny noise; highly recommend. [ Pat  Dec 13, 2017 ]

13 questions already asked

I simply cut the recommended hole size in the ceiling and it fit perfectly. The enclosure is the wall or ceiling. [ JOANNE  Aug 08, 2018 ]
As long as you have an Apple AirPlay 2 compatible device powering the speaker then yea. A list of devices can be found on the web I know Sonos is not compatible now. The speakers do not receive signal without an amp. I have mine hooked up to a receiver in one room and a Sonos amp throughout the rest of my house. [ MATTHEW  Jun 30, 2017 ]
Don't know for sure, but as these are a direct wire attachment to the amplifier I doubt it. [ JOHN  Jun 30, 2017 ]
Yes. They can handle 12 gauge wire. [ Phil  May 30, 2016 ]
Sure, I used 12 gauge with mine. [ Nathan  May 30, 2016 ]
Not a raw 12 ga. wire, but if you use a external speaker wire pin connector you can. [ Mark G.  May 30, 2016 ]
I am running just one of these in a secondary bathroom using a Athem receiver which is rated 90 watts per channel. I am also running under audio zone 2 and this speaker sounds great as stand alone speaker. [ Mark G.  Mar 31, 2016 ]
I'm using a Class T mini amplifier, 25w per channel, and it's more than sufficient. (Topping TP20-MK2) [ Nathan  Mar 31, 2016 ]
I'm running 3 pairs, pushing 70W per channel. These are from a Marantz NR-1605 receiver. All sound crisp and clear. They can tolerate more than my ears can [ Kevin  Mar 30, 2016 ]
I'm using an old yamaha (sorry away from home and can't give you the model #) receiver is 50 watts per channel. I really like these speakers. Easy install and sound really good. [ mark  Mar 30, 2016 ]

I would not. I would find a "marine" speaker that boaters would use. [ Michael  Jan 13, 2016 ]
Yes, I used them in my family room and they sound great with my Denon 5.1. As you might know, with the speakers mounted in the ceiling you don't need to have the sound up quite as loud in order to easily hear your program or music. I think they make the whole experience a great one! [ TOMMY L  Apr 09, 2015 ]
You could but this speaker is like having 2 it takes up four ports on your receiver 2 red 2 black ,which i did not know when i purchase luckily my receiver could accommodate 12 speakers hope this helps [ DARRIN  Apr 09, 2015 ]
Yes Michael. These would work just fine. If these are the speakers you have for your system. They sound great and will be able to give you the channel of audio you are feeding it. [ Tra  Mar 02, 2015 ]
I used them in the ceiling of my family room and they sound great! [ TOMMY L  Mar 02, 2015 ]
This a single speaker with both channels so I don't believe it can be a true left or right You can put the speaker for each channel using 2 speaker I use it in a restroom for the tv in the morning or background music But don't please call crutchfield and ask them ! They are great [ KATHY  Dec 27, 2014 ]
yes it will [ RONALD  Dec 26, 2014 ]
If wiring both sides to one channel does no change the impedance of the speaker, I would say yes. The wider dispersion would enhance the Atmos effect. [ Steve  Dec 26, 2014 ]
Well I can tell you this speaker is awesome!!! It has great sound and something you should know is this speaker is and has the sound of two speakers ,and it takes up two spots for every speaker. YES that's right so if you only have four outputs you use only one speaker there are 4 wires that need to be hook up for this speaker great quality and sound I went with a 12 speaker 1300 watt receiver and love it I needed just 2 of these for my upper level and have 6 of the rectangular polks for my lower level and these are also indoor or outdoor use as well [ DARRIN  Oct 31, 2014 ]
I've only used them as stereo. when I set up my system they sounded pretty good as mono speakers [ VINCENT  May 10, 2014 ]
I've purchased seven of these last year. They should work fine as mono, just need to jump the two channels. I was building a vacation home and used these for outside covered patio that wraps around half of the house, hallway and kitchen. Wanted to be able to hear both channels if you are sitting under one speaker. So I ran two pairs of wire to each speaker, have independent volume controls for each zone at the location of the zone. They sound great. Ric M. Chelan, WA [ RICHARD  May 09, 2014 ]
Bought and installed these in June of 2013. Since I only ran one speaker wire to each location in the ceiling, I opted for these and chose to split the power and ground cords to both channels. I have 4 in my house, they all are better than we could have imagined. Without a doubt I would recommend these. [ JOHN T  May 09, 2014 ]
These are great mono speakers. I have one installed in bathroom ceiling. I made a box between the joists to enhance the bass. I highly recommend them. I cannot comment on using 2 of these in the same room since I have no experience with that. [ ANDREW  May 09, 2014 ]
Yes I painted my MC6s and they turned out really good. The hardest part to paint were the screens but not bad at all with a rattle can. [ JARRIN  Jan 01, 2014 ]
No, I have not [ LOUIS  Dec 31, 2013 ]
Yes, I had the painter match the color for each room and paint the grills and plastic borders. Looks great! I do know he used a special paint but I have no clue what it was. also he sprayed the grills. [ GERALD  Dec 30, 2013 ]
Yea, it was easy. Spray paint the mesh grill seperately and use the included plastic cover while painting the speaker ring/housing. Easiest part of installing these speakers. Any specific questions? [ JOSHUA T  Dec 30, 2013 ]
I would say no. It is actually a two in one speaker with connections for right and left channel. And while it is a great speaker for whole house stereo use it probably does not have the right imaging to be used a s a center channel. [ DANIEL  Dec 18, 2013 ]
Not sure if you want to use this speaker as a center speaker. This speaker is a true stereo speaker and has 4 terminals L+, L-, R+, and R-. If this is what your center channel delivers then this will work fine. Otherwise if your center channel is only C+, C- just get a standard non stereo speaker. [ TOM  Dec 18, 2013 ]
Yes, I suppose you could but I would not make that recommendation. The speaker has dual inputs for both a right and left channel. I used it for a mono speaker off a niles amp (whole house sound) hidden in a small bathroom. It sounds great doing what I wanted but I think Crutchfield could help you with a better choice for a center channel. [ LEE R  Dec 18, 2013 ]
No this is a single stero speaker use as a stand alone unit I did use the standard wall speakers as the center channel with no issues [ KATHY  Dec 18, 2013 ]
I don't believe it is desirable since it is a stereo speaker. It requires a pair of left and right, so it is ideal for a small room to get stereo sound. It is a great small stereo speaker. Polk has a great center channel speaker. It is also great but a little pricey. Technically most speakers that are not stereo would work but the center channel is the hardest working so don't skimp if possible. [ ANDREW  Dec 18, 2013 ]
