Question 7.1 rear surround placement (height and angle)


Standard Member

I just decided to make the move from 5.1 to 7.1 and got some Kef e301 speakers for rear surrounds. The room is about 16 by 14 feet, with 11 foot ceilings. I sit about 8 feet away from my front three speakers (ear level) and 8 feet from my side surrounds (3 feet above ear level). The surround backs would be about 9 feet from the listening position. The couch could be moved back a little, but not more than a foot. It is currently not in the center of the room, but it is only 1.5 feet from the center. We have a custom bookshelf that basically limits my choices of back surround speaker placement to two options.

Option 1: The surround backs are both about 1.5 feet higher than ear level and at a 135 degree angle from the center speaker.

Option 2: The surround backs are both about 4.5 feet higher than ear level but at a freely adjustable angle.

In short, I can position them either lowish and wider or higher and narrower. Which one do you think I should go for? Content will be mostly movies and PS4 games and I will want to go for either 7.1.2 or 7.1.4 Atmos in the future.

Hope you can help.

P.S. I know it is best to experiment, but as a father of a young child I will have a rare chance of 2 days of gaming and movie watching next weekend, which is why I want to be able to setup everything before that. Will tinker later, if needed.

P.P.S I'm Finnish and my spelling is Americanized. Don't let it throw you off too much.
