Ficar Q18

[mdrake]

Does anyone know what the Le is on the Ficar Q18? I can not find it in their specs.

I posted that question on the Fi automotive forum 5 weeks ago and never got a response. Another member emailed Fi a few times and got no response. Good luck with finding that information.

Can anyone measure one? With all this talk of hi Le being a problem and then finding the Fircar is hiding the spec there might just be something to this hi Le theory.

You send me the equipment and I will measure one of them for you.

I asked the question when I was trying to finalize my enclosure dimensions. Here is the response I got.

I don't have it where i am, and i have no way of getting it right now either. Just curious as to why you have to have it? Especially in a home theater format, the only thing you'd need to know inductance for is high frequency extension, and if you are using the subs for what they are intended to be you really don't need to know it..or shouldn't at least...

I pretty much gave up on it after that. I am happy with my end result regardless.

You might also check out this thread, where Steve Callas suggested that I should use a Le of at least 4mH (suggestion) when modeling. http://www.hometheatershack.com/forums/diy-subwoofers-sealed-ported/9830-volume-spl-vs-freq-tradeoff.html#post85659

I have an email into him. I am going to ask him about the Le before I purchase the drivers.
