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?

My room is 14 x 16 and contains Spendor D9’s. I sit 9’ from the speakers. And have what I consider excellent sound stage. BUT I have not heard enough properly setup systems to really have a viable opinion.
Some D7.2 Spendors will work. IMO.

I used to own Sonus Faber Olympica 3 and now own Sonus Faber Amati Traditional I just recently helped  friend outfit and tune his 9’ by 12’ audio room with Wilson Watt Puppies. 

You would be very safe with Olympic 3. They are not huge speakers and if we assume you are going to have a 6’ triangle and place the speakers along the narrow wall (after a year of experimentation that is where we ended up with my friends system) then you have 2.5’ on either side and easily three feet behind... or more. They will sound great with that.

 

One of the great things about Sonus Faber is you can put the speakers really close and pointed right at your a they never get harsh. That is not true with many speakers, They are really flexible in spaces. 

We have treated my friends room... you can turn that system really loud and rock out and it sounds simply fantastic.. I really don’t think you should have any hesitation on Olympica Nova 3. I would imagine that with treatment used at moderate volumes Serefino will sound even better. I guess if it was my money I would get the Serefino.

 

I just went through a slow and methodical movement of my speakers from close to the wall. I have a very large room, so this is not completely applicable to your room. I was surprised, they sounded good a foot or two from the wall, not something I would not be happy with But the best is out about five feet. But it isn’t like night and day... they really sounded great everywhere. If closer, they need more dampening behind to get a really deep soundstage. 

 

@zlone   Dealers/sellers always push stand mounts and sub(s) for smaller rooms. Why? They have you set up for an upgrade path and they have already sold speaker stands and subwoofer(s) that are not needed for the room. The question is how serious and committed with room treatments are you? I would rather spend my money on room treatment then speaker stands and sub(s) that can't be implemented correctly(due to space).in a smaller room.

+1 on the room treatments. Amongst the best money I have spent. 
When I went to audition my D9’s they were at a legit reviewers house. I was actually STUNNED when upon seeing his audio room. And took note of treatments. 
When he found out the size of my room he made strong emphasis to put a sound absorbing panel behind my head. 
Glad I listened.

Your room size is not that much different than mine. I use Audio Note speakers and have them in the corners of my room. Absolutely spectacular.
