What an acoustic nightmare!

How about you first asking about better configurations for the room?

Come on Arny, you can be more helpful than that!

Soundbars usually include LCR channels. Do you have a "soundbar" or a "center channel" requiring the L/R speakers you show in the corners.

In general, speakers don't like boundaries. "On-wall" can be accomodated, the issue is sidewalls when you put speakers in the corner. Pull the L/R out of the corner, closer to the TV. Don't worry so much about surrounds spacing to walls, but realize they belong to the side, not behind the listener in 5.1.

The same is true of ears. You will hear better sound if you put some space behind your head, and will find the best sound toward the room center.

The one exception is bass, where corner subwoofer placement greatly increases SPL capability, at the price of exciting all the room modes. As long as this is not in the basement (concrete/cinder block walls), you may not have bad mode issues.

Speakers normally want to be at ear level, so you hear the on-axis response. CC's can be above or below; do what sounds good and works for you.

16 AWG is fine.

Have fun,
Frank

The best sound is typically produced with all three speakers at the front having their tweeters at the same level, preferably at your ear level while in your main listening position.

Many of us compromise in some fashion, but having your front left and right up high and the center below the TV is going to sound weird when sounds pan across the front.

The surrounds are a bit more flexible, you can have them at ear level or you can mount them a few feet above your listening position. If they're direct radiating speakers it's often best to aim them down a bit if you do mount them high.

That is a judgement that I continue to reserve for myself.

There's no amount of technology that can be thrown at a bad room or bad room layout that will mitigate basic bad planning.

Those who wish to be codependent and in denial can lead the mislead further down unproductive paths if that is what they wish to do.

You need so do something about listening locations that seem to be slammed hard up against what appear to be a highly reflective walls.
