I did all the steps more or less at once. I did not conduct extensive listing test with each step progress. There is some improvement but its not like going from a bad crossover to a perfect one. When you strike the horn after all the above is done there is a dull lower thud and you know its dampened. You could also use the horn to make a cast and then pour the cast with depleated uranium from surplus operation Iraqi Freedom shells. Now that would be dead. tdc
