I have the Ongaro mini compact twin horns which are quite loud when new, but finding even after a couple seasons, they do start to oxidize inside and have to be cleaned and adjusted. Last one I replaced, after pulling it off I decided to take it completely apart and found that the channels were full of some type of fiber material that some insect had built a home/nest in and was in both horns. Cleaned it out and readjusted and they worked again, but doubt would have lasted long due to the multiple times before I had been cleaning and adjusting.
