Default Looking for spec sheet - Vifa M18WO-09-06

Looking through my box of old drivers, I was thinking about doing something with a pair of Vifa M18WO-08-06's that I had laying around from when I picked them up on sale many years ago. These are the *6*-ohm version of the driver. I was wondering if anyone had the data sheet and could give me the electrical specs? I could only find the sheet for the 8-ohm version.

From what I recall, the mechanical parameters were the same between the 4, 6 and 8-ohm version of this driver.

Thanks,

-bill

Thanks, Andrew! I googled around a bit but could only find specs for the 8-ohm version. I think the only thing missing from the above list is the voice coil inductance. Do you have the URL where you found this info?

I'm just getting back into this and it's been years since I designed my last loudspeaker. I know some of this information I should probably derive from the drivers I have in hand. Looks like it's time to go crack open my old copy of the LDC. :-)

Thanks again,

-bill
