That looks 'spot on' to me Sean. I think that's a rather good tool for beginners. That would put me right smack in the middle of medium @ 90 db.

speaker sensitivity dividing lines
What do you consider to be the dividing lines between low sensitivity, medium sensitivity and high sensitivity speakers ? Here are some thoughts on the subject and please keep in mind that i'm basing these spec's on the speaker being fed 1 watt @ 1 meter with the results averaged over a wide frequency bandwidth ( 100 Hz - 10 KHz). While this "somewhat" takes the impedance variance out of the equation due to using 1 watt rather than 2.83 volts, a speaker that is more sensitive may not be "easier" to drive due to high levels of reactance and / or impedance swings. As such, the lines between a "resistive 92 dB speaker" ( medium sensitivity ) and a "reactive 95 dB speaker" ( high sensitivity ) could be blurred in terms of why a big amp can't drive a more sensitive speaker but a smaller ( yet "beefier" ) amp can. Then again, that is a whole 'nother can of worms for another thread.
The reason that i bring this up is that we may all have slightly different ideas as to what is high / low sensitivity. In order to make conversations a little more easily understood and get to a point where we are all on the same page, coming to some type of mutual understanding as to what we are using as reference points might make things easier. I think that this would come in handy for such things as an "Audiogon FAQ's" type of section that will probably pop up sooner or later.
As such, these are the basic guidelines that i tend to follow when looking at speaker sensitivity with the above criteria taken into account. I'd like to hear from others as to what their "dividing lines" are and how we could come up with an "Audiogon reference" when discussing speakers & efficiency ratings.
83 db's and below = ultra low sensitivity
84 - 87 dB's = low sensitivity
88 - 92 dB's = medium sensitivity
93 - 97 dB's = high sensitivity
98 dB's and above = ultra high sensitivity
Obviously, these figures are somewhat random but you have to draw the line somewhere as far as "spec's" or "performance on paper" goes. Any and all comments / suggestions welcome. Sean
