hi, not only i play the piano, but i play the guitar as well. maybe will = make a jam session one day... anyway pay attention (i see that my drawing didn't come out well in the = e-mail) that i am measuring from the input of the driver, to the output = of the driver, BEFORE THE TRANSMISSION LINE. does it still make sense?
