Looking at maybe getting one more vtf-15h for my family room. The room is 14x17 and opens to kitchen then into living room. Right now I've got one vtf-15h next to my front right speaker and was looking at putting the other one next to front left speaker. I'm using a Denon 4311ci with kef q900 fronts and q600 as center speaker. Will this be over kill with two vtf-15h. I can post pictures of the room if that would help thanks.
