The participants on this forum have convinced me wires are best. So I have to wire my basement as we finish it. I'm still thinking on-wall and in-wall are challenges because you have to get it right. For the sacrifice of a little wire showing installing speaker wire terminal plates in the rear is more flexible and if you don't use it solely as a tv room they are unobtrusive if not used. I would put them at the same height as typical power outlets. Although I'm not an audio person, this would be convenient for an enthusiast to plug some giant floor speaker into for big sound. I appreciate any advice.
