Atmos Speaker Placement and Effect

[rgbbhat72]

Hello All

Have the following set up as per attached Diagram
LCR - B&W 603s + HTM6 ( set at 80 Hz)
Front Heights - Polk OWM3 set at 120 Hz
Surrounds - Bose 301s set at 80 hz
Avr : Yamaha A870
BD : Sony UBPX800
TV : LG OLED C8 connected to avr via ARC
No Subwoofer

The Atmos speakers designated as Front Presence are on the Wall directly in line of the Front Speakers. Trying to figure out
a. Whether the placement of the Polks should more to the sides than directly above
b. Any help on the settings/levels
c. TV connected to AVR vide ARC- will this suffice for getting atmos or should i connect vide an optical wire. I watch movies on Netflix /Amazon/Hard Disk/BD

Thank you for your advise.

You say: "The Atmos speakers designated as Front Presence are on the Wall directly in line of the Front Speakers."

That is not the correct position for Atmos Speakers they should be ceiling mounted directly in line of the Front Speakers between your listening position and the Front Speakers.
