Speaker orientation

Good day!

I need some suggestion on orienting my speakers in my room. The dimension of my room is 10ft(L)x9ft(W)x10ft(H). My current speaker is a Logitech z5300 and here are my current plans on orienting them:

Option 1




Option 2




Option 3



Which do you think would produce the best surround sound? Any inputs or comments will be greatly appreciated. Thanks!

My opinion is Option 3. Sound from 5 different angles almost completely surrounds you.

this is a Standard Dolby Digital 5.1 / DPL II Setup.


Or you can use corner arrangement like i do, works great too, as long as you seat in the sweet spot
