The wiring schema for standard AC100 SDL (Super de Luxe) speaker cabinets can be found here.

Below, the schema of the upper compartment of an AC100 SDL speaker cabinet (with basket top trolley) from early 1965 - second generation. Total impedance 15/16 ohms. The lower compartment is arranged similarly. The two were wired in parallel at the input socket, resulting in a total impedance of 8 ohms for the cabinet as a whole.

Wiring schema of the upper compartment of the AC100 SDL speaker cabinet (with basket-top trolley) from early 1965, date codes on the speakers mid December 1964.

Each compartment has a pair of 1uf capacitors, wired in parallel for a total of 2uf - to protect the Goodmans Midax horns from potentially damaging low frequencies.

Detail of the upper compartment of the SDL cab, early 1965.

Note that the right-hand speakers in both compartments have their terminals oriented to the right.

Detail of the lower compartment of the SDL cab, early 1965.

Below, the wiring from the two compartments connected in parallel at the socket.

Detail of the interior "shelf" (compartment divider) with the wiring from the two compartments meeting at the socket.

The first wiring scheme, used in the first five (certainly) or six cabs, is entirely different, the two pairs of capacitors being mounted together in the lower compartment. A schema can be found on this page.
