Sorry for the delayed response.

As far as room treatments, GIK is a sponsor on the forum here and has a way to capture your room dimensions and other info with an online tool. They make recommendations based on that info.

My reco is to start with absorption placed at the speaker mirror points on the side walls - the points where you would see your speakers in a mirror placed along the wall.

You can go from there, a little at a time, following the acoustic panel manufacturer’s suggestions.

I don’t think the sectional couch will be an issue - it will be a great low frequency absorber and will not reflect the sound from the left speaker.

Try removing the coffee table and listening without it. It can make a huge difference. It is a large reflective surface between you and your speakers. You can always put a nice thick comforter on it for critical listening. We use several smaller tables, but with kids this may not be practical as they WILL knock them over and spill your red wine on your beautiful floor.

Fantastic room, we use our combo theater and 2 Chennal room a lot. Movie nights with kids are great!
