Before and after of the Klipsch Forte III upgrade kit. It is a substantial kit weighing about 10lbs on its boards.
Here are the before pictures.
The customer sent their existing crossovers which they had assembled with some "assistance". As you can see there are terminals, anchor screws, jumper wires, and other things inserted unnecessarily into the signal. I did not sort through the mess of wires underneath to determine if the circuits were correct, just carefully desoldered, cleaned leads, and started over. Customer chose to upgrade by adding miflex bypass caps and swapping the resistors to Mills.
Woofer, mid, tweeter circuits are separated to their own boards to allow more space between inductors and to ease installation.
A couple people have asked recently about using terminals or binding posts internally to connect internal wiring between drivers and crossover. Final photo below shows my preferred method. Internal solid strand wiring is soldered directly to the crossover, heatshrinked, and then secured to the board after the solder joint, to eliminate most of the stress from the crossover while manipulating the wire. If it was a possibly fragile capacitor lead, securing the wire twice, nearly eliminates all movement or stress to that connection.
