I have three of my four rear speakers that are in front of windows. I currently have them mounted near the ceiling, but I want to lower them to the correct height in anticipation of upgrading to Atmos. Don't want to do stands due to kids and dogs. I prefer to hang them from the celing. With 9' ceilings this will be 4' or 5' down. Stainless cable would be easy to do, but anyone know of another way, maybe DIY pipe mount or a purchased option?
