I just purchased a beautiful set of 250ti speakers but can't find any information on how to use the many adjustment dials on the backside for both midrange's and the tweeter. The owners manual does not help and the original owner did not remember how to reset each speaker back to neutral or explain how to use the shorting links. Does anyone know of a document that can help me understand the mechanics, how to reset to neutral and optimally adjust the speakers? Thanks for any help.
