How to choose speakers that won't overpower your room?


I am considering buying new floor standing speakers to replace my kef reference ones stand mounts and I'm wondering how to avoid buying something that overpowers my room. My room is fairly small 12 1/2 by 11, And I listened at fairly low volumes mostly jazz and some rock.

I will use Sonus Faber as an example, I'm thinking the Olympica Nova 2 or Nova 3 might be a good fit and I also look at the Serafino, and think that would be very nice as well, but I have no idea if these would be too much for my room. They all look good on paper. And yes, I realize that I have to go listen to these speakers I've never even heard them before, but still auditioning them at a dealer or somewhere else is not the same as putting them in your small room.  Are there any technical details or cue that would tell me whether or not the speaker might be too much for my room?

Bonus question I am going to AXPONA next week is there anything that I absolutely should hear when I am there?

Just stumbled onto this thread, very interesting responses.  I admit to having always believed the "small room = small speakers" axiom, so it's really enlightening to see so many responses indicating that this not necessarily true with some of you successfully running floor standers in what I'd consider a small room.   I stumbled here because I'm considering upgrading, and my room is 11x10, so I'm in just about the same boat as the OP.  I've been trying to rationalize some Wilson Benesch Endeavours in the room, but my "old" knowledge keeps getting in the way, with the continuing thought that they're just too big even though they're technically monitors on stands.   I don't mean to hijack the thread in any way, but I'll just say that it's a bit reassuring to think that maybe I don't need to be so concerned about WB Endeavours in an 11x10 room and I'm glad I found this discussion.

I gave up on subs, maybe it’s in my head but I convinced myself they only blended with my speakers at a specific volume! I even got so bad I bought one of those velodyne subs that came with a volume remote, still no joy, but that’s my insanity. 
 

I was offered a pair of Dali Kore’s for a really hard to refuse price, but refuse I did because I figured they’d overload my room, damn. 
  I heard the KEF ref 3’s in a few rooms at axpona and if anything I thought the mids needed to be tamed most in those little rooms. 
 

Idk of any math calculations to predict bass response, most of the time it’s room nulls I get. You state to listen at fairly low volume so you ought to be with any practical choice 

Maybe Magnepan LRS+ or .7s if you don’t need to rock the house and have an amp that is up to it.

@hbarrel and others. Well the plot is getting quite thick, and I hope the mystery is solved soon. Regarding my original thoughts on Sonus Faber, they were demoing their Stradivari signature speakers with Audio Research mono's at AXPONA, quite the system. I sat front row next to JVS himself for that demo. Other than hearing a great system, it was not a lot of help for me as the scale of the system was just not relevant to my situation.

A few other speaker manufacturers caught my ear. The QLN/Merason/Rossi room was great once again, and was my runner up choice for favorite. I visited the Margules room where they were demoing their amplification and speakers, this was honestly my favorite room at the show. Liquid, beautiful sound. And then, in the adjoining room, Raidho was playing a set of TD-2.2's, also using Margules amplification. I am a soundstage freak, and their system really delivered. 

It so happens I ran across a very good deal on a set of Raidho D-2.1's, the predecessor to the TD-2.2's, and a couple weeks later they were in my room. They were quite reserved out of the gate, but after a couple weeks they started to open up. Strange for a used speaker, but it almost seemed like I was breaking them in again. In the past week I have started getting serious about fine tuning placement, and I would call them quite amazing and honestly well suited to my room size sound-wise, thought just a hair on the big side but I could live with them. 

But wait! That's not all! I came across a set of QLN 3's for sale regionally, and I figured I would forever wonder if I did not give them a try. I am picking them up this weekend, and the Raidho vs. QLN cage match will begin. The Raidho's will be hard to beat, but the reviews for the QLN 3's are pretty gushy.

I will post an update when I know more.
