Atalante 5's

I am still in the hunt for a new set of speakers, previously considering Vandersteen Treo's (https://forum.audiogon.com/discussions/considering-vandersteen-treo), but sort of going cold on those for a few reasons. Talking to a very knowledgeable dealer today about my issues with my current QLN 3's, he strongly recommended I take a look at the Revival line, and specifically the 5's. 

Yes, much has already been said about the Atalante's on this site, but let's freshen it up. I have a few big questions:

- I am a low volume listener, 65-70dB, mostly jazz these days. How do these do at low volumes?

- Topmost is, will these overload my 12.5 x 11' room, conspicuously undersized based on Revival's recommendations.

People seem to love the sound, I would be interested to hear from some jazz listeners and low(er) volume listeners to get their impressions. 

Thanks.
