Vanishing speaker, prominent tone
Visually speaking the 65-RT is quite modest. It has a paintable magnetic grille that mounts flush with the surface of your wall. But look out. You get a 6-1/2" woofer dishing out solid mids and bass, and a 1" pivoting silk dome tweeter reproducing crystalline highs. It all leads to accurate, realistic sound when you fire up an action-packed movie or a track from your favorite band.

Bundle up
Mix and match the 65-RT with other members of Polk's Vanishing RT in-wall and in-ceiling speakers for seamless sound. Grab a pair of 65-RTs for striking stereo sound. Or mix and match them with other members of Polk's Vanishing RT in-wall and in-ceiling speakers for seamless surround sound. The 65-RT RTi speakers. Your system can be as creative as you are.

An optional in-wall bracket is recommended for installing the 65RT in a new home under construction.

Product Research

Vanishing Series In-Wall Loudspeakers: The Polk Audio Vanishing Series 65-RT in-wall loudspeaker features a precision-engineered, minimally flanged design. Polk's exclusive Sheer-Grille protrudes only 7mm from its surroundings, and installs virtually-flush in your wall. Mounting the speaker is simple with a one-cut, drop-in installation and the rotating cam stabilizing system. The speaker provides superior high-performance sound from its 6.5" woofer and aimable 1" tweeter with Reflective Room Compensation control.

Driver Technology

Dynamic Balance Technology: Laser-imaging technology allows Polk Audio engineers to see the entire vibrating surface of a driver and tweeter. This allows the engineers to actually see performance-robbing distortion develop on the speaker cone. Using this data, they can determine the Dynamic Balance of their high-tech materials, and alter the geometry and construction of the speaker to effectively tune out the offending resonance. Exclusive Dynamic Balance Composite Material Technology delivers sound that is effortlessly clean and clear, even at lifelike volume levels.

Klippel Optimized Motor Structures: The Klippel Distortion Analyzer allows Polk engineers to optimize each driver's motor structure, voice coil alignment and suspension to insure smooth, unimpeded movement even at extreme listening levels. This is especially important in the shallow depth area afforded an in-wall loudspeaker.

Woofer: The 65-RT in-wall loudspeaker employs a 6.5" Dynamic Balance mineral composite polypropylene cone woofer with a rubber surround for a smooth, consistent frequency response. The driver features a lightweight, strong composite basket that works in conjunction with Klippel Optimization to keep moving parts in rigid alignment while further damping performance-robbing resonances.

Silk Dome Tweeter: The speaker employs a 1" Dynamic Balance silk polymer composite dome tweeter for crisp, clear imaging. The high-performance tweeter features a 15° swivel housing, for more direct high frequency control, excellent off-axis imaging and more placement flexibility.

Reflective Room (Tweeter) Compensation Control: An easily accessible Reflective Room (Tweeter) Compensation switch allows you to make detailed adjustments to optimize the sound for any installation. The switch can be used to digitally compensate for harsh reflective surfaces. The switch doesn't merely reduce high frequencies, it actually allows you to notch-out a specific area of the spectrum (3500-6000Hz) where room acoustics most often interfere with performance. The switch has two settings:

  • Filter Setting: If your listening room is very reflective, with smooth sheetrock walls, hardwood floors, and non-cushioned furniture, the sound will be overly bright and unnatural. Selecting the Filter setting compensates for the effect of reflectivity in a hard room. Tweeter attenuation flattens room response, without hindering higher frequency response, for warmer, more realistic sound and more accurate imaging.
  • Normal Setting: If your room is not reflective, with curtains, artwork, lots of cushioned furniture and carpeting, sound will be absorbed by the room, resulting in more realistic reproduction and more accurate imaging. In this case, select the Normal setting.

Timbre-Matched: The Polk Audio Vanishing Series in-wall loudspeakers are timbre-matched to Polk Audio's high-performance RTi bookshelf and floor-standing loudspeakers. This allows you to match them to an existing Polk Audio home theater speaker system and enjoy seamless blending from speaker to speaker. Timbre-matched speaker components will insure the same true response throughout your system.

Frequency Response: The overall frequency response of the in-wall speaker is 32Hz to 27kHz, and the -3dB frequency response is 50 to 25kHz.

Infinite Enclosure Design

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

PowerPort Bass Venting: The 65-RT features Polk Audio's patented PowerPort Bass Venting. The oblong-shaped port has rounded edges which smooth air turbulence at the mouth of the port to eliminate distortion. A foam rubber port plug is included, and should be inserted when the speaker is installed in an area larger than a standard open stud bay.

Wafer-Thin Sheer-Grille: The Polk Audio Vanishing Series in-wall speakers feature Polk's exclusive wafer-thin Sheer-Grille, a magnetically-secured grille that protrudes only 7mm from its surroundings. The Sheer-Grille can be painted to match your décor, making it virtually indistinguishable from its surroundings. The Sheer-Grille has nearly transparent, ultra-small perfs, and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms.

Note: When painting the grille, it is highly recommend that you use a can of spray paint matched to the color of the surrounding wall. Brushes or rollers should not be used to paint the grille, as this will clog the perf holes.


Gold-Plated Spring-Loaded Posts: The 65-RT has a gold-plated pair of spring-loaded binding posts that can accept up to 12-gauge wire, single banana plugs, or pin connectors.

Mounting Options

Applications: You can use the Polk Audio Vanishing Series in-wall loudspeaker as stealth side or rear surround speakers in an RTi theater system setup, or for superior dynamics in practically invisible multi-zone music systems.

Rotating Cam System: The speaker utilizes a rotating cam system to ensure a secure, vibration-free installation. There are six rotating cams to hold the speaker securely to the wall.

Installation: The 65-RT can be installed in new or existing construction:

  • Existing Construction: In existing walls, use the included cardboard template for one-cut, drop-in simplicity.
  • New Construction: Pre-construction brackets (sold separately) are available for new-build or open-wall retro-fitting.

Good price and minimal install depth. [ W  Jun 19, 2017 ]
I was looking for an in-wall speaker that would work with the RTiA series floor speakers and this fits the bill. [ Adam  Apr 29, 2017 ]
Provides the lower bass sounds to cover a larger firepit pation area outside I needed, have used Polk speakers on my boat so I know that the weather proof design will stand up outside. I compared with the Bose 691 speakers, they were a lot more money, when you try and compare them many categories for Bose were not listed. They were $100 more as well, all in all this made the most sense for me. [ RON  Apr 18, 2017 ]
Reviews were excellent. [ Gregory  Mar 31, 2017 ]
Recommended by Chance and it's now on sale. [ Lynwood  Mar 15, 2017 ]

Heard a all good things about it, yet to experience [ SREENIVAS  Jan 04, 2016 ]

7 questions already asked

I'm not sure understand the ?. Why would you want to connect headphones to the speaker lines? Unless things have changed since I was young (there are rocks younger than me) headphone cannot handle the power req'd to run speakers & they will melt (sort of)- not to mention you going deaf. In the old days, amps had a special headphone jack that was low output- came off the pre-amp. In modern amps w/Bluetooth, use the Bluetooth function & get your self some good Bluetooth headphones- s/b good to go. [ Fred P.  Apr 15, 2017 ]
Those are in-wall speakers. Once installed there are no external connection points. You need to look on your receiver for any headphone connections. [ Thomas  Apr 15, 2017 ]
Don't recall, they have been installed in the wall a couple years. [ Edeard  Dec 02, 2016 ]
Yes you can [ raul  Dec 01, 2016 ]
Yes, if you have the standard 16" (or larger) stud spacing. [ Richard  Jun 13, 2016 ]
I would be concerned with exposure to moisture. If this is not a concern, I see no reason why it would not work in the ceiling. [ Jeffrey  Jun 13, 2016 ]
I suppose it could, but the 65rt takes advantage of "sound box" inside of wall. Ceiling installations don't have that resonance because they are normally open. To get good quality audio in ceiling one needs to build a sound box around the 65rt. Also, please take into account the environmental requirements for the 65rt. I do not remember temperature requirements and how that relates to your specific patio installation. I am pretty sure the 65rt is not specified for wet or even damp locations so that might be your limiting factor even before beginning to engineer and build sound boxes. In short, you might want to look for a speaker rated for damp locations or even a marine speaker. [ Bryan  Jun 13, 2016 ]
Well, that would depend on how far apart the wall studs are located where you want to cut the holes in the drywall. Otherwise, the (4) mounting clips should hold just as effectively horizontally as vertically. [ CECIL W  Jan 15, 2016 ]
Don't see why not. [ Jason  Jan 14, 2016 ]
there is no problem with a hoirzontal install being mindful of the spacing of the wall stud at the proposed location. hope this helps [ THOMAS J  Jan 13, 2016 ]
Yes, if there is room between your studs. [ Edeard  Jan 13, 2016 ]
Yes they can be installed horizontally. I don't know how it affects the sound quality. [ R MARK  Jan 13, 2016 ]
I don't see any reason why you can't mount them horizontally. I mounted mine vertical because the room has side indents that fit them well. They do sound great. [ Jeffrey  Jan 13, 2016 ]
There is nothing restricting you from installing horizontally. Personally, I prefer my tweeters to be higher than the woofer and have my bass resonate down. [ COLIN  Jan 13, 2016 ]
The spring clips require no additional space. They will push up against the studs when extended regardless of the room left for them. Colin 2/15/16 [ Colin  Feb 16, 2016 ]
The cut-out template should allow the appropriate overhang for the spring clips to fasten. It's been a while since I installed mine, but believe 8" should be adequate. There are 4 clips: 1 up, 1 down, 1 left, and 1 right. [ CECIL W  Oct 23, 2015 ]
can you go above and bellow the speakers. i think the clips can be snugged up in that way. can always route out the defined areas in the studs. speakers O D in that dimention is 9 inches. hope this helps [ THOMAS J  Oct 14, 2015 ]
You can definitely install them in the ceiling. Physical installation should not be much different than installing in a wall. However, I do not know how this would affect the sound coming from the speaker. I think it would not be ideal since the speaker is designed for wall mounting. There are other Polk speakers that are designed for a ceiling mount that would be more appropriate. [ R MARK  Jan 24, 2016 ]
There should be no issue physically installing these speakers in the ceiling. However, I'm not sure it they are designed for proper sound dispersion from the ceiling. Crutchfield or Polk could better weigh in on that aspect. [ R MARK  May 03, 2015 ]
Yes. they work the exact same way as the "ceiling" speakers except they are rectangular instead of round. Just check for joists. [ Kyle  Apr 23, 2015 ]
Yes. No problem installing them in a ceiling. Great speakers. Hard to beat Polk. Enjoy. Tor [ TOR  Apr 22, 2015 ]
Yes they could. However, I would be hesitant to do so if the ceiling means the attic and exposure to that heat. [ Edeard  Apr 22, 2015 ]
Yes, even Polk Audio support on their website says "Yes, the difference is just for aesthetics. In-wall can be installed in-ceiling.". However, I think the 70-RT is better suited to ceiling installations because the 65-RT PowerPort Bass venting system takes advantage of the wall space between studs sandwiched between the sheetrock. You won't likely have that reflective type of space in ceiling, but you could build an enclosure for the 65-RT if mounting in ceiling. [ Bryan  Apr 22, 2015 ]
Yes. They sound great! [ Anthony  Apr 22, 2015 ]
I would go with ceiling speakers for the rear surrounds but not the front. Maybe do some bookshelf speakers on stands. I did install these in the front but the wall was taken apart and even then I had to move a bunch of electric wires and switches out of the way. You never know what you may find in your ceiling either. There could be extra beams, joists, wires, plumbing etc. [ POD666  Apr 22, 2015 ]
I don't know. Polk's website isn't much help, either. Sorry! [ RALPH D.  Apr 13, 2015 ]
