Speaker advice for Heights

[Rev2S]

Hi all.  I have a Denon 4300 and using Monitor Audio (front, rear and center) and Elac speakers (heights).  The sensitivity is between 85 db and 90 db with RMS at 80 and 100 watts.   If I end up getting additional speakers for heights that are 60 watts for RMS and 84 db sensitivity....is that too low to be efficient or would it harm anything? 

Thanks!

Assuming the Atmos speakers are a lot closer to you than your LCR's, then, not a problem.

Your Denon 4300 should have a suite of tools to reign in the dB differences you're going to see if using speakers with different sensitivities. It has Audyssey MultEQ XT32 support. The easiest fix would be to run Audyssey and it should correct any major issues you might have with these mixed and matched speakers. I'm not too familiar with this Denon but you might be able to tell it the sensitivity and it will compensate automatically as well even without running Audyssey.
