PMC EB1i impedance curve

[Jerome W]

Hello folks, and Ian especially,

Can we get a table of the impedance curve / frequency of the EB1i somewhere ?
If not, do you the minimal impedance of it ? for which frequency ?
Thanks a lot !

Jérôme.......I hope you have better luck that I did with this request. I asked PMC in Great Britain for the EB1i's impedance/phase curve chart, and never got a response. I emailed them several times, but no information was ever sent to me. I asked Ian on this forum, and he saud he would find the information, but it never came.

Thanks Dan !

And you don't have the instruments to take the measures by yourself I guess...
too bad when one thinks about all the gear you have in the studio !

Jérôme.......Those test instruments are sophisticated and very expensive to own for occasional use. I had hoped to see Stereophile put the PMC EB1i through a full review. They would have done those tests and published them.

Yes Dan, I can imagine.
I suppose that if PMC does not communicate on that, it could be because of a very tortured curve !

This is pretty accurate.

I tried getting to Stereophile for review the EB1i. They instead chose the DB1i.

I wouldn't hold your breath for an impedance curve.

Are you guys running into problems with powering your EB's?

Ian.......If memory serves me right, somewhere I saw an impedance and phase curve chart on the EB1i, but failed to bookmark it, and have not been able to locate it again. It would seem to me that this data would be readily available from the factory. Surely, Peter Thomas has made these tests on all of his designs. Why is it so difficult to get this information?

This is the post where I inquired about the EB1i impedance and phase data over two years ago. http://audioaficionado.org/19302-post1.html

Here is an impedance and phase curve chart that was publish in HiFi Crtitic for the IB2i. Sorry, but it wasn't any clearer in the web page.
