Are you having issues with noise when you keep the outlet velocity under 700 ft./min.? Are you experiencing them being noisy AF no matter how much volume you put through them? I’m not familiar with that specific register, the 700 number is assumption on my part as far as Max velocity goes. By the way AF stands for airflow in case somebody thinks something else.

If its in the customers budget get a manual j&d . Find a person to do a site visit. What state are you in?
