HF/MF enclosure, back portion. All sealed, save for the HF unit, fairly easy to remove - loosen screw, slide wooden block, lift tweeter out.

One and only crossover, mounted on bottom "cover" of the LF enclosure (where the spiked feet are mounted). I can post the bottom (trace) view of this board, if anyone is interested...

Left side: inputs to the crossover (biwired inputs)
Right side: outputs to LF drivers
Bottom: connections still visible to the multiwire royal cord connecting to the HF/MF enclosure..

I have KEF 103/4's (vintage 1992), and need to replace the Uni-Q driver in one of them. Unfortunately, I dissassembled the driver without noting which internal wires went to which posts on the driver. Does anyone happen to know the wiring schema for the Uni-Q driver. I need to know where the yellow, green, brown, and blue wires coming from the crossover connect to the mid-range and tweeter posts on the actual driver. Thanks!
