Budget is not a concern as much as space and the ability to wall or upper shelf mount 

Thanks for the info what I meant by best was stellar sound quality and if they put a decent volume that’s a bonus we’re all pretty much audiophiles here so you know what I’m actually looking for

What’s your budget, are you looking new or used, what’s your amplifier, where will they be placed in the room, what’s your room size, and what sound characteristics are you looking for?  Need lots more info to make any meaningful recommendations here.  Right now we’re shooting in the dark.  Plus, there is no best.  The only “best” is what sounds best to you, which we can’t know without the above info.  The more you share here, the better and more useful and targeted recommendations you’ll get. 

What an odd question...

You mean like lying around and periodically updated?

Fitz , Joseph, Hsu, Monitor Audio and Focal should give you a nice overview
