He probably would if he were allowed to spend that much on speakers. I think my mom would commit homicide if he went that route. For the space he will have set up I think the 100s would be incredible. I've told him he needs to update his QS8s simply because the v4 speakers are a major upgrade even if he stayed with the v4 QS8s.
I will see how well I can position the 10s on the wall. 2 feet down might be feasible. 3 feet only if I have them set back 15-20 degrees behind MLP but I don't want to get them too close to the walls that kick back into the room.
