Wiring and Testing Crossovers

The next step is to install the binding posts, and wire up the crossover networks. The Kitty Kats are setup for bi-wiring and as such we had to drill two additional holes for the extra binding posts. The spacing on the holes pre-drilled in the Parts Express cabinets are too close together in our opinion. We drilled the additional holes 1" farther to the outside with the idea that we could put the two ground in the center where they are closer spaced.

The Kitty Kat crossovers wire up very nicely to the four binding posts with the grounds in the center and the woofer to the left and tweeter to the right. Double nuts are used and sealed with lock-tite (the removable kind).

After the boxes were wired we decided to test each crossover for correct operation. The drivers were assigned to each box and labeled, and then connected to a Creek Audio Classic 5350SE integrated amp driven from a Sony CD player. We checked that each crossover was working and that the audio was in-phase between cabinets, etc. We also ran the Kitty Kats overnight using a break-in disk (more about this unusual test CD later). Once we were satisfied that all the drivers and crossovers were working OK, we then disconnected the drivers and put them back into their boxes.
