It's true that high efficiency and high sensitivity aren't the same thing, but only in how they're quantified. Efficiency is measured as the percentage of acoustical watts produced per electrical watt input, sensitivity is measured as decibels output per watt or volt input. Thus if one says a speaker is 90dB efficient they're using the wrong term. That's not unusual, this forum misuses the term in its name.There is a direct linear relationship between the two, but efficiency is almost never used, partly because there's no easy way to measure acoustical watts, whereas measuring decibels is simple. Most speaker modeling software doesn't give efficiency numbers, but HornResp does. If you look at an efficiency chart it's obvious why the spec is almost never used, as the peaks and valleys can run at 10:1 and higher ratios.
