I think when we get to the point that a 30 pound speaker is too much to handle , it might be time to just stay home and sip tea
I prefer doing sports outdoors and weight lifting in a gym instead of dragging 30 pound speakers to church weddings where they are exaggerated.
BTW, I consider your answer to my post by far the most stupid answer I ever got in this forum. For instance, what would you say to a great musician who can't lift 30 pounds due to severe back problems? - "Stay home and sip tea?"
