For the life of me, I can't seem to.

I've been trying to figure out resistive damping of dual voice coil woofers.

First I went to Adire:

http://www.adireaudio.com/Files/TechPapers/RDOOperation.pdf

I put the eq.s into Excel, but the higher the damping resistor, the closer you get to the original Qts and no higher. At Rl=0 the Qts is halved (more or less)

Then I went here:

Same story. Either there's something fundamentally wrong with the eq.s as written, or I'm so far out in left field I cant see the plate from here.

Has anybody fooled with this before?
