Goodmans 18" Audiom 90 Bass Speaker - 50W power handling
Late 1963 / early 1964
Used in the very earliest Foundation Bass cabs. The Audiom 90, which had been developed by Goodmans for organs, was the only 18" bass speaker available at the time.
Vox used the 15ohm version of the Audiom 90.

Black label - 16 ohms (normally) - 50W
Used singly in Foundation bass cabs accompanying AC50s, and in pairs of cabs accompanying AC100s. If two cabs were plugged into an AC100, the amp's impedance would be set at 8ohms.
FANE 183 - 16ohms - 60W
Used relatively infrequently by both Vox and Selmer for their bass cabs. Later versions of the speaker became more popular in the 1970s with the rise of other British amp manufacturers, notably Hiwatt.
