## 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...
