A perennial customer favorite

Meet Polk Audio's RC80i. This value-packed pair of 8" in-ceiling speakers has been delighting our customers for years. And with good reason — not only do they sound fantastic, but they come with a lifetime warranty. Use them in your home theater for thrilling overhead surround sound. Or install a pair in any room where you want to enjoy music.

"Fantastic speakers for the price!"

"We couldn't be happier with the performance with these speakers! Simple to install, look good and sound great!”

— Jeremy, a happy Crutchfield customer from Denver, Colorado 

Elevate your home theater

Planning a Dolby Atmos® or DTS:X® system? Use the RC80is for lifelike overhead sound effects. You'll love how sound moves up and down, instead of just side-to-side and front-to-back. These speakers are great options for the rear surround channels of your system, too.

Enjoy music in any room

Putting speakers in the ceiling for music with minimal visual clutter? Each RC80i is equipped with a robust 8" woofer for solid bass. And a swiveling tweeter lets you direct sound towards for you for the best sound.

Polk even uses moisture-resistant materials so you can install these in your bathroom, kitchen or covered porch with confidence. 

DIY installation

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.

Polk's rotating-cam design makes your in-ceiling installation go smoother. Once you have the RC80is in place, simply use a screwdriver to tighten each cam for a secure grip against the back of the ceiling.

Optional pre-construction brackets are recommended for new construction. Free lifetime technical support is provided with every Crutchfield purchase.

looking for quality and value built in speakers - with enough low end energy. Shipping was quick and templates make install easy to understand. Used with RC85i for both surround and ambient sound in several rooms.

Features

Dynamic Balance Technology: Dynamic Balance drivers are used for wide, smooth response and low distortion.

Woofers: Each speaker features an 8" Dynamic Balance, mineral-filled polypropylene woofer for clean midrange and deep, accurate bass. For a smoother response and improved durability, each woofer uses a rubber surround.

Tweeters: Each speaker uses a 1" Dynamic Balance, metalized soft dome tweeter in a ball-and-socket swivel mount. The aimable tweeters give you direct high-frequency control, resulting in excellent imaging even for off-axis listening positions.

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 speakers in bathrooms, kitchens, saunas, even under the eaves of an enclosed porch. (The speaker is not recommended for exposed outdoor use.)<.p>

Mounting Options

Installation: The round shape and flush-design allow the RC80i to mimic the look of a recessed lighting fixture. Each speaker requires a cutout of 9.375" and a mounting depth of 3.25". Each speaker frame has a diameter of 10.685". Once the holes are cut, each speaker can be dropped in and the Rotating Cams can be tightened, allowing you to secure each speaker to the drywall without any extra assembly. If you will not be mounting these speakers in drywall, make sure the wall or ceiling material can safely support the weight of the speakers before installation; each speaker weighs approximately 4.5 pounds.

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

I am setting up 5.1.2 Atmos Audio in my TV (home theater) room. These speakers seem like a nice balance of price and performance.

value for intro speakers [ BRENDA  Dec 15, 2015 ]
I have a home under construction and I was looking for a good set of in-ceiling speakers that didn't break the bank. Crutchfield had the Polk Audio RC80i's on sale for $99/pair, which is a great value considering they are normally $149/pair. They have better than average freq. response (35hz - 20khz) and good sensitivity at 90dB and they will handle the 95 watts rms @ 8 ohms that my Onkyo receiver puts out. Thanks for a Great Buy Crutchfield. Happy Customer!!! Can't wait to hear them! [ Mr.  Dec 14, 2015 ]
Superior reviews, great price! [ Kevin  Dec 12, 2015 ]
Reviews and the Price [ Gerry  Dec 11, 2015 ]
Great sound for the price; tweeter can be aimed to optimize sound over the primary sound field. Installed a pair in the ceiling for a recent kitchen remodel and they provide great sound over entire 12'x28' space. [ Jeffrey  Dec 08, 2015 ]

18 questions already asked

I have mine located in a small bathroom about 2 feet away from the shower that gets little beads of water from the steam and 3 years later it's still working. Excellent quality speakers for the money. [ ZACHARY  Jun 01, 2017 ]
Thanks for your question. For information on selecting the best speaker(s) to go with your Onkyo receiver, I would recommend reaching out to an Advisor directly by phone (1-800-324-9695) or online chat. They can offer more personalized advice to ensure you're getting the best performance and quality. [ Larry  May 02, 2017 ]  Staff
Thanks for your question. Each speaker weighs approximately 4.5 pounds. Hope that helps. [ Kenny  Apr 14, 2017 ]  Staff
my ceiling speakers are all at different lengths. I did not see an issue [ Richard  Apr 09, 2016 ]
Think not, input travels at the speed of light to the speaker. Should be ok unless speakers are in different solar systems. [ DALE  Apr 08, 2016 ]
Length doesn't matter as long as you have the speakers connected from source to the speaker. I bought a pair and love them. They sound excellent! [ MARK  Apr 08, 2016 ]
I'm happy to help. I bought 4 Spks 2 years ago. Working very good at 30x50 ft. 10 ft ceiling. I think you should get 8 Spks. Installing 2 rows. Sound very good. You can get 6 Spks then you can turn volum up more. I hope this can help you. [ Tam  Nov 05, 2015 ]
I forwarded your question to an Advisor and they responded with the following: These speakers are not a perfect voice match to the CSiA6 center channel speaker. The Polk in-ceiling RT series speakers are a match for your center channel speaker. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Sep 01, 2015 ]  Staff
yes, we have in a few instances [ Daniel  Aug 24, 2015 ]
I would think the weight of any speaker would pull through a ceiling tile. I think I'd look into using speaker brackets and wiring those up to something that can support the weight. Then there would be a plastic ring just on the other side of the ceiling tile to mount to. [ ERIC  Aug 24, 2015 ]
Yes, not an issue. I have them in my basement with suspended ceiling (drop ceiling). They sound absolutely amazing with crisp sound. I couldn't be happier with this set of speakers. [ Nick  Aug 24, 2015 ]
Yes [ JOSHUA  Aug 24, 2015 ]
Shari, the speakers come with all the gear to mount them into the wall. All you have to do is cut a hole with the template. There are no exterior brackets [ SCOTT D  Jun 09, 2015 ]
They DO NOT. I really didn't need them. They come with a template to cut your hole. Once you have done this you and have wired then you push the speaker up into the ceiling. The hole is smaller than the flange. You then turn 4 tabs with a screw driver from below and tighten. Slip on the metal grill cover and you are good to go. If by chance you are mounting outside on an overhang I would suggest you spray paint the grill and flange with a good out door paint to match. I had a previous pair that rusted. I did this as a prevention on the replacements. Hope this helps. They really are good speakers and fairly priced. [ JAMES S  Jun 08, 2015 ]
Yes, they do! [ WILLIAM  Jun 08, 2015 ]
No [ WILLIAM  Jun 07, 2015 ]
No, you need to purchase the pre construction brackets separately. [ KENNETH  Jun 07, 2015 ]
no they have a template for the hole to cut but have a bracket built into speaker that mounts them to drywall [ AL  Jun 07, 2015 ]
You guys are awesome!! I guess I can pull this thread now. Thx a bunch heap!!! M [ Sportsman550  Jan 20, 2015 ]
I replaced Bic Speakers with the Polk. They are exactly the same. Probably both made at the same place in China. Who knows? Anyway, I still have the Bics and I just measured them. They were an exact match so my cut out was the same and perfect. The diameter of the white ring around the speaker is 10 and 3.4ths inches and the diameter of the slip in grill that covers the speaker is 9 and 1/8 inch. Hope this helps. By the way, I am using these outside at house overhang near swimming pool. Using a Onkyo AV Receiver about 120 watts. Works fine. Think my cut out was 9.5 inchs. [ JAMES S  Jan 19, 2015 ]
Thanks brother!, that's what I needed [ Sportsman550  Jan 19, 2015 ]
O/D of the grill is 10.5". [ STEVE  Jan 18, 2015 ]
Never replace an inwall with a smaller one. You may get vibration or distortion from air pass through. It way better to buy a speaker with a slightly larger diameter even though you may have to enlarge the hole. [ George  Jan 18, 2015 ]
The weight of the speaker can cause sag issues with the ceiling tile, but they make brackets that span 24" (typical ceiling tile dimension that support the weight across the span from metal track to metal track. Let me explain better, the "bracket" is a flat metal plate with a hole that will allow the speaker to slip thru while holding the speakersecurely in place. To see what the brackets look like search " drop ceiling speaker bracket" under any search engine and it should show images. [ GEORGE  Jan 11, 2015 ]
i dont know the answer to this--my speakers were installed in a wall-not a ceiling [ PHIL  Jan 02, 2015 ]
I forwarded your question to an Advisor and they responded with the following: The Polk RC series speakers do not voice match any other series. You should get another RC80i to use for the center channel speaker. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Sep 04, 2014 ]  Staff
They are indoor speakers, but it shouldn't be a problem being under a covered porch. Only make sure the porch roof has no moisture coming through. Enjoy! [ MARIO L  Aug 21, 2014 ]
We put them in a little over a year ago in boxed in eaves on our back deck that is exposed to some pretty severe weather conditions here in central Oregon. We get both below freezing temps during the winter and above 90 in the summer and they have performed well and sound great! No problems. [ WILLIAM  Aug 18, 2014 ]
Yes as long as not heavy moisture. I put them in my bathroom ceiling so they can handle some moisture. Nice speakers too by the way. [ Doug  Aug 17, 2014 ]
I have used these speakers in my basement. However, as per product specifications it is constructed of durable, moisture-resistant materials for use in bathrooms, saunas, or under outdoor eaves. [ SANJAY  Aug 17, 2014 ]
Sound for these are amazing... Don't know about the weather concerns you have but in az I would have no problem trusting these for at least 4-5 years [ BRADLEY  Aug 17, 2014 ]
Yes that's where mine are. And awesome! [ LUIS  Aug 17, 2014 ]
The speakers do not need to be installed as pairs as there is no left or right speaker. Having said that, I'm assuming that you will be using a monaural signal, otherwise the sound will be off. I used this pair in my kitchen ceiling, but found that I needed to supplement the bass with a subwoofer to get the deep sound that I wanted. The treble and midrange is excellent, for an overall sound that is good. If you want deep bass without adding a subwoofer, you may want to chose a different speaker. [ John  May 08, 2014 ]
Then your room would not be in stereo and would give a mono sound output [ BRAD  May 08, 2014 ]
You could do just one speaker per room but you'll lose the "stereo" effect. So, if the vocal is coming out of the left speaker because of the way the music was recorded, then you won't hear it in the room with the right speaker (unless you can tell your receiver to send "mono" or one signal carrying both the left and right signals). Most of the time what you're looking to do will sound ok, but with music and movies it's unlikely to be great. [ CASEY  May 07, 2014 ]
We bought the rc80i by mistake - they do need to be put up in pairs. We intended to get and did get the MC80 which are individual speakers which sound great on their own. I would recommend them. [ BILL  May 07, 2014 ]
No they can be set up as one. But of course it would sound way better as pairs. Good luck mine sound amazing. [ LUIS  May 07, 2014 ]
I mounted mine in 5/8 drywall, I am sure they would work in 3/4. [ BRET A  May 08, 2014 ]
Yes. As the previous reviewer answered, there are 4 long mounting screws that use a rotating cam to pull the speaker to the wall/ceiling. I used these speakers on 5/8 inch drywall. 3/4 inch should be no problem. [ John  May 08, 2014 ]
Yes, the screw mounts are adjustable. [ CLEVELAND  May 08, 2014 ]
I forwarded your question to an Advisor and they responded with the following: I think that would be a great addition to your home! A lot of our customers use those speakers for that application. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Mar 28, 2014 ]  Staff
The backside of the speaker will be exposed so you will want to keep any insulation off of the speaker. [ THOMAS  Mar 19, 2014 ]
yes, i use cheap plastic shower caps to cover the speakers(cut little hole for speaker wire to get thru. hope you find this helpful [ JOHN  Feb 18, 2014 ]
we also have blown in insulation and what we did is cleared the insulation away and put a little plywood box over the area just to make it safe but it doesn't seem like it would hurt to have the insulation on speaker. [ WILLIAM  Feb 18, 2014 ]
When I installed both of my speakers I cleared the blown insulation away from the speakers. I didn't want to take a chance on the insulation messing up the speakers [ MARK  Feb 18, 2014 ]
My install was in new construction. I put 2x4s on either side of the speaker from rafter to rafter and then screwed a piece of plywood over the top before blowing in insulation. I was a little worried about the insulation packing down inside the speaker and affecting the performance. [ THOMAS  Feb 17, 2014 ]
Not sure. I used foam insulation. Better contact polk [ Doug  Feb 17, 2014 ]
I'd recommend using speaker baffles no only for protection, peace of mind and sound quality. http://www.crutchfield.com/g_762/Foam-Speaker-Baffles.html [ MARIO L  Feb 17, 2014 ]
I would recommend some sort of barrier like a speaker baffles. Not only is there a protection element, but peace of mind. The benefit also, is that sound quality is improved with putting covers on. An alternative is using tupperware dishes deep enough to cover the exposed back side. http://www.crutchfield.com/p_237XT55/XTC-5-1-4-Speaker-Baffles-3-3-4-depth.html?tp=2809 [ MARIO L  Feb 17, 2014 ]
Yes. I haven't noticed anything abnormal with sound quality. This is a very good speaker for the money! [ ANDRE L  Feb 17, 2014 ]
Hmm. Crutchfield sent this to me, but it should be answered by the manufacturer. I would think that, since speakers move, they shouldn't have blown in insulation surrounding them. [ JEFFREY  Feb 17, 2014 ]
EIther would work, really more about the distance from the stereo not the size of the speaker. [ ROBERT M  Jan 16, 2014 ]
Depends on the length of the cable. We are using 16 to cover about 20 foot lengths. Beyond that, I would use 14. [ CURT V  Jan 13, 2014 ]
I believe I used 16 ga in wall rated. I will double ck when I get home from work today. [ THOMAS A  Jan 13, 2014 ]
I'm pretty sure I have 16 gauge wire for all of my speakers. Works just fine. [ JEFFREY  Jan 13, 2014 ]
I used 16 gauge and they sound great! [ CLINT  Jan 13, 2014 ]
yes you can use 16 gauge wire but if you are running long distance then you better off using 14 gauge. [ ASMA  Jan 12, 2014 ]
According to the crutchfield website, if you're less than 50' you can use 16 gauge wire unless you have high end equipment and want to improve sound. [ CHRISTOPHER K  Jan 12, 2014 ]
Yes. The lower the gauge the better (generally), but 16 gauge should work perfectly unless you're running it further than 25 feet. [ CASEY  Jan 12, 2014 ]
