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'

A doubling of amplifier power gives an increase of 3dB. So at 20 watts it
would be 95dB. And so on.
