After looking at the graphs for both the frequency and impedance curve it baffles me that it's a top rated 4ohm driver at
parts express, even though the usable frequency range extends down to 1500Hz the impedance curve will force you to cross it over at 2000Hz but we already know that all tweeters should be crossed over at 3000Hz so it's a moot point to begin with.
The frequency response from 2000Hz to about 9000Hz is actually quite jagged and then has huge rounded peak to about 11000Hz and drops off quickly on the way to 20000Hz and 5.5ohms impedance.
Reviewers brag on it's extended frequency response and smooth linear transition but i sure can't see it from looking at the graph..
Now i am thinking i got the wrong speakers, it's nothing that a properly designed crossover wouldn't fix but i could have done better, a lot better.
