Polk Audio 70-RT 3-Way in-Ceiling Speaker, Surround Sound Speaker, (2.5” Driver, 7” Sub) - Vanishing Series | Power Port | Paintable Grille | Dual Band-Pass Bass Ports, White

As another person put it, I'm not at all a Polk devotee, but I've installed several of Polk's other less costly in-ceiling speakers and was impressed with them... so the fact that these are even better and hold up to the reviews made me very happy. I'm extremely pleased with them at all levels: sound and seeming build quality, mounting ease and aesthetics are all a notch above the lower series speakers. Most importantly, their sound quality is considerably above what I would consider average for an in-ceiling speaker--especially in the mid-bass, which is a large part of why I purchased them for my 5.1 system (hoping they would hold up to the reviews). Installation was simple (in a new home that was prewired) and they're by far the most "invisible" of any ceiling speaker I've seen; the grill is extremely low profile (probably due do the magnetic design) and as a result, it hides the larger mounting ring that is considerably more visible even in Polk's own lower series speakers. I was especially pleased to realize these had upgraded wiring posts, making it easier for them to accept and solidly clampt the larger guage wire that we had our home wired with. I was a bit nervous in using one for my center channel, but I'm glad I did--again, it blends in perfectly and my concern over the "imaging" being wrong as a result of the height and down firing ended up being a non-issue. Granted, my TV is mounted arguably a bit too high above my fireplace mantel, so this may help the situation, but while I could easily mount a traditional in-wall center directly below the TV, I'm definitely not going to waste the effort or money to do so since I'm not convinced it would do any better. While these caused me to go a bit over my original budget (my wife enjoyed heckling me about this), they've panned out to be well worh it and I would recommend them to anyone that wants an in-ceiling system that's considerably above average on all points.

Excellent ceiling speakers if you are discerning about sound quality. I am not a Polk devotee at all. My regular speakers are, shall we say, more esoteric. But these have raised my estimation of Polk! Often in ceiling speakers sound awful, tinny, or boomy, etc. But these have a very sweet and smooth midrange (which is key); likely due to the fact that unlike almost all other in-ceiling speakers in this price range, it has 3 drivers, one for mid-range so it does not have to compromise mid-range for bass response. And it has good tight bass (not HUGE base, but proper bass); this is likely due to the design of the woofer and the housing, which is also pretty unique and allows it to be larger and resonate more than typical 6.5" sized ceiling speakers. I used two of these in 15x20 ft space that is open all three sides and they produce plenty of sound. Easily driven by a 20 watt amp. No enclosure in the ceiling required. Sound great just in the ceiling cavity. One note, these are quite deep and heavy relative compared to other ceiling speakers of this size. Pay attention to the dimensions to make sure they fit in your ceiling space. Also note, price is for ONE. So they are a step up in price. But at least three steps up in quality. Strongly recommend these.

Measurement result captured with MINIDSP UMIK-1 Microphone. Speaker mounted in a DIY-ed cabinet made with 16mm MDF. Stuffed with 45mm fiberglass acoustic insulation. I've made this cabinet for all my in-ceiling speaker. Note you NEED CABINET for in-wall and in-Ceiling speaker otherwise you are paying 5 times more for what you are listening to. (or getting inferior sound). Blue curve shows frequency response with the buttom setting switched to "normal" whereas brown curve is when switched to "reflective". Basically it reduces 3k-15k by around 3db. Both setting generates quite neutral sound - Note this is the IN ROOM FREQUENCY RESPONSE it tends to be ugly and fluctuating. Still it is quite flat and smooth. Wonderful speaker made by polk. I can only say, wow, what a bargain.

Spent probably too many hours researching speakers for the new home theater setup, but knew I wanted in-wall / in-ceiling speakers. Used the 70s for surround (right rear, right back, left rear, left back) in a 7.2 setup and the sound is amazing. These speakers are deep or tall depending on your perspective and the crossovers are exposed into the attic space / ceiling. Plan for something (baffles, bags, boxes, etc.) to keep them covered from the elements (blazing summer heat) and/or insulation and dust. Extremely happy with the sound and product quality and the included templates make it impossible to not cut the openings correctly. "Vanishing Series" is a great name because you hardly notice they are even there. I still have some fine tuning / calibration that can be done, but out-of-the-box with the receivers auto-calibration they sound great. I only expect them to get better with some tweaking

Acquired 4 of these to install in our new house in a living room home theater as Dolby Atmos / DTS:X height channels mounted in a hollow ceiling. Lucky enough to have a fairly deep ceiling so could go with these 3-way speakers over the classic MC-60/80 speakers people often opt for in this kind of setup (and only for a small increase in cost) First of all, do not let my 4 star overall review discourage you in terms of good these speakers are, I am a bit of an audiophile and hold speakers to fairly high standards and a 4 star rating is pretty good IMHO. The build quality is very good and they feel like a solid piece of equipment when you first unbox it, weighing in at around 6.5 pounds they are not flimsy but still light enough not to worry about mounting them in regular drywall ceilings. The electronics all feel like quality components and my only concern is having them exposed inside a ceiling where dust will accumulate, for which I have acquired some speaker bags to wrap them in prior to mounting them. The speaker connectors are gold plated and generally I could not hear any signal noise outside of what I normally can with the same wires on my regular Hi-Fi System Audio fronts. Upon receiving my 4 speakers I took a few hours out of my day yesterday to test them prior to mounting them in the new house in the coming weeks. I should note, they were all tested as shown on the picture attached, meaning not mounted in a closed environment which will reduce some of the base a little. The sound quality for these speakers are quite good, however there is a very noticeable drop-off in the mid-range to bass where the clarity clearly drops where the volume of the deep frequencies simply does not stack up with the mid-range driver as well as the powerful dome tweeter which dominates the sound field. After adjusting with some EQ on the stereo receiver I used for the resting boosting the bass with 4 DB I re-ran testing with some demanding music incl. Skrillex, Metallica (Lightning and Black Album), Game of Thrones S8 Soundtrack, Jupiter from the Planets. With the EQ adjustment I was able to balance out the powerful mid-range and high's to get a fuller sound stage (I did not connect any sub for all this for the record) which was quite impressive to hear after having heard them in their native mode without any EQ. The most impressive change I noticed came with the excellent recording of GoT S8's track 23 "Stay a thousand years" @ 1 min 39 seconds where the strings fade in to compliment the choir creating a very smooth transition between the deeps of the strings (cello's and bases) and the highs of the female section of choir and the violins. Similarly on track 32 "A song of ice and fire" where a deep base of cello's and percussion forms a foundation of the overall GoT theme song with a choir providing lyrics in a the high frequency range. These speakers really held their own without any help from a sub, but obviously needed the EQ adjustment. Where they came into trouble was with slightly more complex sound stages such as Skrillxx' "Kyoto" where the electronic deep base drums forms the base of the sound stage complimented with high pitch electronica and a clear overpowering by the mids and highs were a constant issue even with EQ. Now this is obviously an extreme test since these speakers never were designed for providing single source output for demanding music such as dub-step. Putting these in a Atmos heights being able to provide good frequency response down to about 150 hz. without loosing too much volume compared to the mid's and high's (ohh and they can play LOUD!) combine with some good non-directional base from a (set of) sub I am pretty sure you will tremble under the thunder or fighter jets over your head in a well mixed Atmos track. For those who can fit these into their ceiling's I highly recommend them for height channels, if you are looking to build theater setup's utilizing only ceiling/wall mounted speakers (I first recommend you to abandon this idea) you might be able to get enough base from these but you may find the sound field too flat since they do not have a directional tweeter and will send the sound downwards with some dispersion. Will update if the final Atmos setup yields any other results worth of notice.

I purchased these surround speakers because I already use Polk speakers in my home theater. Also, my particular set up does not allow the typical half-hexagon surround speaker to be used; I had to use in-ceiling speakers. These "vanishing brand" of speakers have the thinnest bezel, you don't even notice them in my ceiling. The built-in subwoofer really, and I mean really, makes a difference in sound. I used to use Polk A1 bookshelf speakers as my rear surround speakers, and I still have these speakers, now doing duty as my rear back surrounds speakers to give me a 7.1 system. Using these in-ceiling speakers compared to the other Polk speakers I can really tell the sound difference. Bass is present with these that just is not there in the bookshelf polks! Do not hesitate, And do not worry about matching these to a particular series of Polk speakers, or even with other manufacturers. Surround speakers do much less of the "work" of a typical 5.1 or 7.1 speaker system.

I initially 2 of these to install in my master bedroom. I was so pleased with its performance that I ended up getting 2 more for my Home Office. Totally worth it. They are relatively easy to install and yes, dont forget to use the inwall rated speaker wire with these.

I bought these to use as a pair of surround speakers in a 5.1 setup. I have a large living/family/kitchen area with ceiling heights of just under 12'. Since this area is very open I did not want to add some large speakers hanging from the ceiling and looking out of place. These RT70s are flush mount and conceal very well into the ceiling. My neighbor came over to take a look and he did not see them at first mounted in the ceiling. He thought they were just another vent or recessed light! Once these were connected and ran the amp's audio settings wizard the room really filled with sound. The kids enjoy it the most and they really like watching their movies and TV shows in surround sound. I have not yet had a chance to listen to Transformers on Blu-Ray, but I am expecting it to sound great!

Primero compre una para escucharla tiene buen sonido en agudos se oyen claro lo que se debe tener en cuenta es el espacio del plafon para que entre ya que es alta y ponerla con cuidado para no maltratar los componentes ya que no trae protección se ven geniales sin la tapa

Purchased these for side and rear speakers. They sound great and we’re easy enough to install. As others mentioned, make sure you have space as they are tall. I have newer style I-beam joists and these were fine for my application. The magnetic white grill blends nicely. When I do my demos for friends they say they never noticed them until I pointed them out.

These are some of the best sounding in-ceiling speakers available, provided you have the height clearance available in the ceiling space. The Polks have a very clean and detailed sound unlike many other ceiling speakers. Would recommend them if you are appreciate great sound quality but dont want big obtrusive speakers sitting in the room.

It’s amazing! First I wasn’t expecting that much awesome sound. Recommended.

Great sounding speakers and they look great.
