Review: Perfect for creating your Dolby Atmos system - Yeah, you just can't beat these guys for the price and the sound. I use them as Atmos speakers in my home theater room. They sound great and almost disappear into a white ceiling. Super easy installation. The directional tweeters offer a nice level of sound adjustment you just won't get with a fixed tweeter. My room is on the smaller side, so I only needed a pair of them. Well worth the money. They would also work well as stand alone ceiling audio speakers.
Review: Sound Incredible - Love, love, love these speakers. They changed my movie watching experience. It feels like I’m actually there in real life when watching movies. They sound better than the speakers at my local theater. They are an excellent value for the money as well. Being able to paint the speaker grilles makes it so I don’t even notice them. They look fantastic. They are a great value for the price. I never imagined they would sound this good at this price. They work very well. II highly recommend for them your home theater room. Very simple installation.

## Questions & Answers

**Q: what is the depth needed in the wall?**
A: PDF spec sheet indicates 2 3/8 " needed assuming mounted to 1/2" drywall

**Q: Do you need a subwoofer for these speakers? Or do they sound ok without it?**
A: I have a pair of these in a wall which are zone 2 speakers for a receiver which does music only and no subwoofer is possible (most receivers only have a sub input for zone 1). I have to say it sounds damn good, though I did place them up near the ceiling and close to walls to optimise the bass. So in this this situation you do not need a sub. If they are part of a home theatre setup then I'd recommend a sub (as I would with any speaker that is not floor standing capable to reaching some really low frequencies).

**Q: can I paint it with my wall color?**
A: Yes you can paint it your wall color.  The speakers come with a clear plastic insert which act as masks for the frame.  The preferred and probably the best method to paint the frames and grill is with sprayed paint...you can spray your custom paint with a kit available at your better paint store.  You can also use a small roller but be careful with the grill so that you don't fill in the hole. Several very light coats are best here.

**Q: I need them for a concrete wall. is their any problem ? what's the depth of the hole I need to make ?**
A: I think you have many challenges with installing the Polk RC65i into a concrete wall.  Overall dimensions (w x h x d) are 8 5/8" x 12 1/6" x 2 7/8".  The RC65i requires a 1/2" or 5/8" drywall to mount effectively.  If you have drywall over the top of your concrete wall, then this should work (although running the speaker wiring presents its own challenge).  The opening in the concrete wall will be larger than the drywall (yet another challenge).  I think I would look at a excellent Polk mini-speaker and surface mount that speaker versus tackling the "in ceiling speaker in a concrete wall challenge".  But - if you make it work, post your solution to the community as I'm sure they would appreciate the how-to knowledge.

### ⭐⭐⭐⭐⭐ Great speakers for the price but...
*by P***S on February 25, 2013*

Bought these from Amazon 1-1/2 years ago and had them in storage till I decided to do a little audio system in our master bathroom. Installation was very easy, even though I had to use a grinder to do the cutouts. I do not know what everyone is talking about when they complain about the six screw locks that it comes with? I found them actually very convenient and easy to work with. Once everything was installed, the sound went on and one speaker sounded amazing, BUT the other speakers tweeter was not working at all. I tested the bad tweeter on the good speakers crossover board directly, and it proved that the tweeter itself was bad. I kept the speakers in storage without ever moving them or banging them, so this is obviously a manufacturers defect. Since my Amazon warranty is obviously expired, I went online to try and purchase this tweeter, and after a long search, I found the RD0086-1 tweeter on sale for 70 DOLLARS!!! The cost of this little plastic encased tweeter is actually MORE expensive that the entire speaker brand new - WITH the tweeter included!!! So forget that option. Warrant is no good, so I guess I have to just buy another speaker altogether. But wait... to top it off, these speakers come IN PAIRS, which means I am now forced to buy TWO speakers, just because one tweeter is bad! That REALLY annoys me to no end. I am back to square one and having to make the entire purchase all over again because one plastic encased tiny tweeter is bad from the factory. The only thing on my end that was wrong was that I had to wait 1-1/2 years to do the actual install, which allowed my warranty to expire. I could not help that in this case. So, as far as the speakers goes, I have to still give it a full 5 stars for the great sound they produce for the money, the ease of installation and the great Amazon service. The fact that I got screwed in this case is I am sure an aberration, so I will not factor that in. Every great product has its day, and I guess it was my turn. I am going to reorder these again, and am sure they will work just fine this time. But for the little I have heard the one good one, it does have clear highs, deep bass for their size, and just a nice overall sound. Imagine my updated review when i get TWO speakers working together at the same time? Lol Keep you guys posted... Pete
