[QUOTE="bbe22, post: 854291, member: 863"] drivers that measure to the nearest 10%would be quite acceptable On the tweeter sweeps the max impedance peak and the relative curves that is close vz each other are more useful , they appear to be in good condition....... On the mids/bass SPL (ie sensitivity) imp max and QTS matters and there again you are very close >>>> reality check would be in the cone mass ( Mms) (calculated value) in the results , if this is way different between the 2, then in all probability there was a measurement error your comment re the pitch of a note does not apply.... eg in a completed speaker if the signal sent through from source, is 400 Hz this is what the driver executes, no more no less.... .....................If the speaker parameters are way off in rare cases this should be addressed in the Xover - to result in a balanced pair in the end, or look for better drivers to start with It makes life so much easier to have accurate results, as you posted :) [/QUOTE]
