Best monitor for bookcase ?

I'm using a pair of Harbeth HL-P3ES-2 monitor speakers in a similar situation. Although they are not inside a bookcase, they are sitting on the top shelf of a bookcase against wall corners. They are a sealed design and, I believe, are even marketed to some degree as 'bookshelf' speakers. Great sounding little speakers with a devoted (and well justified IMHO) following.

I heard a pair of Induction Dynamics bookshelf speakers crammed right back against the wall, with books packed in all around them. And they still sounded incredible! For whatever reason, these speakers don't seem to mind having walls/books in close proximity.

Thanks to all of you for the comments . It just doesn't seem practical to have to have a dedicated sound room for thousands of us . I know not to choose a rear ported monitor .

B&W makes a wall mounted speaker, similar to the 805s.
I've seen it in the Signature finish but have not had a listen.
