So, I have a denon 1910 and I just noticed that I can set up front heights as 7.1. Currently, 5.1 is working well. Rears are about 2 feet above ear height LR are ear height and center is about 1 ft below ear height but angled up so it points directly at er height of seating position. My question is, before I go and borrow 2 speakers from a buddy (same model as my rears) and set all this up, will I get a benefit if these 2 front highs if they were placed just to the side of the TV "inside" the width of the LR channels? Height will be on the low boy where the center and TV sits. Any opinions and advice on this would be appreciated.
