Goodmans 18" Audiom 90 Bass Speaker - 50W power handling

The Goodmans Audiom 90 was the first British-made 18" bass driver. The magnet was alnico. Its primary purpose was as an organ speaker. It seems to have done service in cinemas too. There were several iterations (as usual with Goodmans) and 6ohm, 8ohm and 15ohm versions. These are fairly rare these days and when they do come onto the market, fabulously expensive.

Above, an early example from the late 1950s/early 1960s - 6ohms.

A later 15ohm version. It is likely that these were used by Vox in the earliest Foundation Bass speaker cabinets. The Celestion 18" T1074, which came on to the market in early 1964, was adopted for around six months thereafter. A label for the Audiom 90 15ohm unit is preserved in the book of labels kept by the firm that did the printing for Goodmans - .

50W and 100W power handling

In late 1964 / early 1965, Vox moved back to Goodmans - the new Audiom 91 with a more cost effective ceramic magnet. There were two versions: 100W power handling, 8 ohms (blue label), and 50W, 15-16 ohms (black label). The 50W version was the version normally used in the Foundation Bass speaker cabinets accompanying Vox AC50s.

Labels - original unused.

Blue label - 8 ohms (normally) - 100W

With power handling of 100W, these could be used singly with AC50s or AC100s. The die-cast frames are substantial.

A Goodmans unit from 1967 with a new "...Manufactured for Jennings Musical Industries" label. Stocks of these passed to Vox Sound Equipment Ltd, the company that sprang from the ashes of JMI.

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.
