That is all well and true....but you are comparing apples and oranges.
If you re-read what you quoted me on, you will see that I'm just tyring to state the the final load presented to the amp is what matters when determining stability - not the coil cofig or the number of subs you wire up.
I can hook 2, 10, 500 drivers up to the same amplifier channel so long as the load is within spec.
You seem to be making a big deal out of the fact that some woofers are built with dual coils. The fact of the matter is that for all intensive purposes there is no inherent benefit to a DVC sub except for flexibility.
Now you can wire a sub two different ways and present two different loads then you could before, or you can use two amplifier channels (or two amplifiers even) to power a DVC sub. The same goes for subs with quad coils.
The amplifier simply doesn't care, so long as the load is within spec....it doesn't matter how you get there!!
