If you are measuring a multi-way system (2 or more bands/drivers), 1KHz is a good midband point to assess overall sensitivity and, if constructed properly, the sensitivities of the rest of the range will be commensurate.

Agreed.

And one further point - human hearing is most sensitive in the midband range of frequencies (typically around 1 -3 khz). At frequency extremes, human hearing capability is not very consistent. So focusing on a frequency of 1khz for example makes physical sense - particularly in the context of a finished speaker because as you suggest, if it's properly constructed, it should have similar sensitivity at all other frequencies. When talking about a subwoofer or woofer, a 1khz sensitivity rating makes little sense. And as others have suggested, some of the better manufacturers have for years listed an average sensitivity rating over a specified frequency range of interest - particular ly driver manufacturers.
- Human hearing is up to 8 dB more sensitive at 3kHz - Ole Lund Christensen 10:03:04 08/04/12 (1)
  compared to 1 kHz.

    And that makes 1Khz a better compromise for a wide-range speaker, rather than a public address speaker.
