I am wondering if there are any advantages to a single or a dual voice coil woofer. (The apparent drawback to me is that the DVC woofer ends up being 8Ohm.) Are there any other pluses or minuses?

You could have a DVC driver with 2 16 ohm voice coils, wire them in parallel and get 8 ohms or you could have 2 4 ohm voice coils and wire them in series to get 8 ohms. Voice coils vary in value from make and model, but typically you see 4 or 8 ohm voice coils in home audio DIY applications. In the car audio realm 2 ohm voice coils are not all that uncommon.

I can't tell if your question is leading to a specific driver or if you are just asking the question for learning purposes. If you're out for learning here's an article about speaker impedence, it does not relate specifically to single or dual voice coils but you'll learn all about Ohms law.

In general dual voice coil woofers allow for more wiring options. I do not believe there are audible differences in the same driver that has single or dual voice coils.

for one, flexibility in power for the DVC sub.

for example, your DVC sub can be wired to 2 ohms and ask for more power from an amp (assuming that's a dvc 4 ohm driver)
