Looks complicated
I would say I did (and have still got in the lounge now) the KEF Q series range of speakers that were BIG and I just couldn't get them to work in the constraints of the new room. They wouldn't fit with seating included, across the room so I went for those smaller wall mounted items that don't take up too much width in the room. I kept the Q55 floorstanders for the front Left and Right channels as can be seen in the pics.
The benefit of CAD to lay the room out with models of each item was, I have to say, invaluable
Was easy when you start from scratch so I just found some smaller speakers to use whilst maintaining sound quality if that makes sense? With a sub, I don't really miss anything from having the larger speakers so it's worked out well.
