Bookshelf Speakers for Large Room

Is there a way to post a picture?  I cannot find a way.

The space where the speakers sit is about 22” deep.

I did not answer your last two questions:
I will pair a good amp to the speakers, right now if I go with the Sonus Faber I will probably get D’Agostino amp.  I do literally listen to all music but classic rock is probably my favorite but my list is long and diverse.  I work from home and usually sit in the sweet spot with my laptop or iPad.

I also host a lot (or did before the pandemic) so having great sound during get togethers is important as well.

I uploaded a picture of my built in.  I currently have KEF R series speakers that I am upgrading.  Here is a link.

Why not buy them?  I probably will.  I listened to them and loved them.  The reason I am asking is because all of the other bookshelves I have listened to were $6K-$8K and these are $16K.  I just want to make sure I am not missing something that is out there.  Wilson only has the Tunetot, B$W the 805’s, and there is not much around me (Orlando) that I have found to sample.  

As for the sub, I currently have dual Sunfire subs but they are in the cabinet behind acoustically transparent material.  I will see how well they sound with the SF’s.  I do watch movies and so really need subs, but I want them to blend well with music first and foremost.

Thank you all for the reply’s and great feedback.  I have some research to do.  

The shelves above the speakers are adjustable and removable.  At least up to the top of the tv, then it is a solid piece of wood.

I wish I could listen to some of these speaker recommendations, I am very curious but also limited to what is available.  I have always been intrigued by Salk but they don’t have dealers, but if I ever make it to Michigan I want to check them out.

I really like my local dealer that has let me sample several different speakers in my home, it has been helpful.  

I know it seems like such a waste to buy such expensive speakers just to limit them by placement.  My plan is to use them for great sound when watching movies, fill the room with beautiful music if just hanging out at home or when I have guests.  But then pull out the stands ad move them away from the wall when I want to really sit in front of them enjoy a great sound stage and listen to music as it was intended.  My wife is gone all day at work (or will be once she goes back) and I work from home so I have 9 hours to set up the speakers, work, and enjoy.

Thanks again, I really love this hobby, the community is the best!
