speakers for small room

Magico A3s work great in my 15’ sq listening room pushing them with Hegel H590. Anything bigger would probably be overkill. Retail for about 16k but available used for under 10. Picked mine up for 9 on the US Audio Mart site. I find that people will justify selling them at a loss when they find “end game” speakers at 50-60% of retail and decide to move up. All genres sound good to me on the A3. It’s the quality of the recordings that make the difference in listening pleasure.

I would definitely consider using dsp room correction. My results are night and day and I’ve tried to do room treatments in the past. Floor standers, room correction and at least one sub would be my suggestion. IMO Lyngdorf RP is the cats meow. I haven’t heard many others besides the cheapy home theater receivers room correction and it was not good for music. 

On the particular Lyngdorf unit if you play vinyl just be aware is digitizes everything. If you can get over that it sounds awesome, sounds like vinyl should. 

I recommended Pulsars earlier, but if your room can handle floorstanders I’d recommend the Perspective 2 as it’ll give you a bit more scale.

Another possibility would be Spatial Audio speakers that are a dipole design and are very good at scaling up depending on the music.

Just a couple more options for you to chew on. 
 

I missed the fact your room is open on one side.  So it appears you listen in an area that is smaller than the overall room side.  Seems like more information is needed.  Duke brings up several things to be taken into consideration.  To start, I think we need to know the overall room size and which wall is open in relation to the speakers and your listening position.
