I recently replaced the binding post on one of my cornwall II's with the set klipsch had available and recommended(out of the original). Binding posts are actually thicker... so i had to modify the holes in crossover. also the nuts that hold the posts on are thicker. Looked everywhere and could only find something in the middle of the new thick one and the old thin ones. Placed washers(plastic) on the three screws to try and make everything even. Now there is a slight vibration at certain bass levels. Questions are is anyone familiar with the difference im talking about between the new and old binding post? and if there are any recommendations on what to do. also i am not totally opposed to updating the crossovers... just wonder what that entails. pricing shipping and so on. I have notice BEC does some crossover work. wouldnt mind his thoughts. Thanks in advance. Any questions just ask.
