I'm curious on the accuracy of my Eminence Delta 15A woofer (used in Theater 4 Pi speaker xover). On their spec. page they show:

Coil Inductance (Le) = 0.86 mH
Coil Impedance (Re) = 6.9 ohms

Using the above, C5 = 18uF and R3 = 8.625

But when using my LCR digital multi-meter to measure the actual woofer I get:

Coil Inductance (Le) = 0.66 mH
Coil Impedance (Re) = 6.5 ohms

Using the above, C5 = 15.62uF and R3 = 8.125 ohms

Should I use C5 & R3 values that I measured with my LCR meter or should I just stick with say a 20mH inductor as mentioned from other previous posts? Is it that Eminence's specification shows a "nominal" value and what I get with my LCR meter will be different?
