I have a quick question. I built wayne J's veritas and started to use them last week. One of my Mid drivers seems to be making a a funny noise. During play it is not as clear as the other mid range driver. There seems to be a bit of a raspy sound to it. Would this be because of something not being right in the crossover or is the driver defective. It sounds like a rasp or a vibration with in the sound. It is hard to explain.
