Considering Energy’s liberal definition of the word “transducer”, I would refute their claim. Now if they want to get specific, and detail exactly what part of the driver (aka transducer) they are referring to that needs break in, I may be inclined to give their rational some thoughtful deliberation. I still have not heard any compelling argument that will substantiate that speakers need to be “broke in”. Just don’t pour the juice to them when they are cold.
