Hi,
In some datasheets (namely Fostex) there is more than one curve in the frequency response plots. I'm not talking about the impedance-curve, the ones with the numbers 4,8 and 16 are puzzling me. Does a deliberate output impedance/speaker impedance mismatch help to gain sensitivity? Is this only possible with tubeamps then (given the OPT has appropriate taps)?

Hi,
let's take a Fostex datasheet for example: http://www.fostexinternational.com/docs/speaker_comp/pdf/fx120.pdf
The 3 frequency response curves are taken with the mic on axis, 30° off axis, 60° off axis.
Are these you are questioning?

Oh, that makes sense. Never seen a datasheet with such annotations before. The first time I came across such a plot was http://www.fostexinternational.com/docs/speaker_comp/pdf/fe108ez.pdf and it has "4, 8, 16" next to the three lines, which made me think...
Thanks for clearing this up!
But still, I've heard rumors that a deliberate impedance mismatch can have positive efects. How? Why?
Anyone?
