Best Smaller Bookshelf Speakers For Use Exclusively With Ambient Music?

As the title says, these speakers will be used in a small room (10x12) exclusively for listening to ambient music. Think Eno, Will Ackerman, Sigur Ros, Ludovico Einaudi, Dead Can Dance, Enya, George Winston, etc. 

This is an important purchase as I listen to 2.5-3 hours of this music, six nights a week, to wind down from stressful work days. 

Thanks for any assistance with this.
