If your room can accept the bass of the Alexia, my suggestion is surely the Alexia2 - IMO overall superior to the Sasha. The Alexia borders the realm of speakers like the Alex or XLF - a larger scale and better soundstage with getter height than the Sasha or WPs. Unless you are a freak of detail (the Sasha V is excellent in this aspect) consider an Alexia 2.
Edit - just saw I have given similar advice two years ago ...![]()
I have a dedicated room that is 16x21x9. I should have no issue with the Alexia. I am using a pair of REL G1 MK2 subs now and the room doesn't overload and I listen loud.
