The speaker has a unique, wafer-thin grille that can be painted to match the decor is magnetically secured to deliver nearly transparent, ultra-small perfs and dynamic, unimpeded sound. The ceiling & in-wall speakers are compatible with Polk Audio RTi speakers for seamless blending between traditional and built-in speaker systems. Perfect Fit templates, a precision flange, (available) pre-construction brackets and the patented Rotating Cam system ensure secure, vibration-free installation.

Review: Installed 5 in a 5.1 setup and am very pleased - 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.
Review: A Revelation of how good celling speakers can sound! - 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.

## Questions & Answers

**Q: are the tweeter angles adjustable?**
A: No, the angle is not adjustable.However, both the tweeter and the main driver are not "flat" facing directly downwards; both are mounted tilted at a fixed angle.  And since you can rotate the speaker, you have reasonable postition nadjustment towards the listening point.Besides... sound quality is AWESOME!!!

**Q: es una o dos bocinas?**
A: Yes

**Q: Anybody match this line up with any monitor series towers? How do they sound together? I got some 70s...**
A: I guess you will use your Monitor Series tower speakers as front speakers and the in-ceiling 70-RT as rear/surround speakers.Haven't done that exact match.  However, I checked specs for the Monitor Series towers and the RT floor standing speakers the RT-70 are designed to match.  Both speakers are full range (as the RT-70) and appear to have the same tweeter (1" silk/plymer).  Midrange and Subwoofer differ a bit in size and type.My guess is, considering the RT-70s specs and superb performance (I use mine in a 2.1 arrangement in my bedroom), any acoustic mis-match (if any) should be hard no notice.  I would say, go ahead!

**Q: Can i install 7 polk audio 70rt speakers for 7.1 system**
A: Yes, if you have a hollow ceiling and you want discreteley mounted recessed speakers, I'm sure these will work great!Polk has available in-ceiling subwoofers, or you can hide the sub behind a couch or sofa...

### ⭐⭐⭐⭐⭐ Measurements says everything
*by Q***0 on February 7, 2021*

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.
