Yeah that’s what I’ve used on front left and right, with a larger piece of tv wires.Glad you're enjoying your new gear!
On a side note, I can highly recommend this stuff to hide any speaker wires. It's called "D Line Trunking"

The micro stuff is good for speaker cable. For thicker cables (HDMI, coax, ethernet etc), get the 30x15mm stuff.
Going to glue gun the front heights wire down the corners of the wall. It’s a thinner wire and easily to paint over. Just waiting for a new glue gun .
Still playing with settings. There a lot to learn/ play with .
