help me find the t/s per. for these speakers

[Korndog]

man.. i just got these speakers off ebay and i've been searching and searching for some t/s perameters, but no luck. they are Focal 5.25" speakers made for Jmlab sib speaker system, 3ohm, 75wrms, the serial # on the back is A42805-02sbd-fm. they sound DAMN good in a sealed box, but i'd really like to make a ported one for them. if anyone could get it for me, i would REALLY appriciate it

I think theres really only two ways to find it. Either E-mail Focal and ask or use a computer program to pull the T/S specs. You can use Speaker Workshop to get the actual T/S params for those drivers. You would have to build a JIG which is I beleive just a few resistors. Speaker workshop is totally free but it is a bit tricky to use.

i did email focal but they couldn't help me because these are replacements intended for jmlab sib system
i'm gonna look into this jig thing though, doesn't sound too difficult. thanks man!

Good Luck. I've being trying to get T/S parameters for my a/d/s sub for nearly a year, but the customer support of DEI is complete crap.

If you have a decent sound card it shouldnt be hard to get them using speaker workshop. The Vas may be a bit hard since you have to load the cone down. But the other T/S params should be able to be pulled by the computer. You just need a simpl JIG (i think it's just a 10 ohm resistor) to hook the subwoofer driver to the computer.
