...After rebuilding the crossovers on the Wharfdale W35’s I was reacquainted with just how good, and simple an old school sold brass screw with a Thumb nut is. For the $50 bucks one pair of Cardas binding posts costs you can purchase enough copper screws, bolts, and thumb nuts to refurbish a bunch of speakers with a connection that is every bit as good as anything no matter the price.
