Hi Elliott. Sorry, it was a real busy weekend. Thank you for the advice above as well as the follow up.
To your point, I found the following article which was really interesting: https://www.glasswolf.net/papers/polyfill.html
Based on that, it would recommend about 4 lb of Polyfill for this speaker. I already have some leftover Owens Corning Thermafiber mineral wool insulation, so I may go with that. Does that sound about right to you?
Also, with mineral wool, do I not need to worry about covering it?
