Impendace correcting for drivers


2001-01-29 9:58 pm
I am currently building a set of small speakers. The bass-driver needs to be impendance corrected and therefore I need the points on the impendance curve where Z = Znom and Z=2Znom. Now, since I have access to an LCR-meter, can I measure the self-inductance of the voicecoil and then just calculate the frequency using the standard formula XL = 2pi*f*L where XL equals either Znom or 2Znom ?? Will this work or do I have to measure the impendance using the standard setup with a function generator and 2 volt- /ampmeters?

Any help appreciated
