Specifically, I found myself wondering while looking at the Eminence site's page on the Maverick speaker: where does the power go? With a conventional attenuator, it's pretty straightforward that the shunted power is dissipated as waste heat. With an FDM speaker, there is no load resistance burning off the excess power, the magnetic flux is just progressively decoupled.
As the speaker is increasingly decoupled, I'd guess it appears significantly less inductive to the amp, with a change in the resultant impedance the amp sees. Maybe it just begins to approach the DC value of coil resistance, and the most of the power load is borne by the voice coil?
Anybody got the lowdown?
