To spare my remaining active braincell (see other recent post) could
someone kindly tell me what the speaker sensitivity figure for 1 Watt
would be if the brochure (IMF TLS 80s) quotes:

'Efficiency measured via Pink Noise at 1 metre for 40 Watts = 98 dB'

It sounds like the standard AES test method. You apply 1 watt of input power (in
the speaker's operating frequency band - coulde be swept sinewave or you can use
noise) and measure the SPL at 1 metre in an anechoic or free space environment.

98dB is typical of 'PA' speakers rather than hi-fi.
