Wiring verstility and increased availability to use more than one amp. Quad voice coil configurations are the same idea, just more versatility and more, blah, blah, blah.....

Well the DVC and QVC allow for more choices on how to hook your system up. If you have an amp that puts out 100 Watts at 4 Ohm, or the same amp puts out 200 Watts at 2 Ohm which way would you want it. Well the answer to that is up to your own taste. With a SVC single sub I am limited on how I hook it up. Even with a SVC Dual Sub set up the best I can get if they are 4 Ohm subs is 2 Ohms. What if I want 1 Ohm for my 2 subs. I need 2 DVC 4 Ohms.

Each VC can handle a certain amount of power. You also have to factor in Magnet Size. Why are there subs out there with 40 Oz Mag when there are others with 300 OZ mag. It comes down to power handling and what the individual wants. It just gives you are better power handling sub with more options on how you want to do your install. It allows the compition guys the ability to get the most bang at the lowest rated Watts for his amp.

Correct me if I am wrong ( I have not been in the comp seen for a long time) but this is how it used to be. If I have a SVC sub running at 4 Ohms and my amp like I said before is rated at 100 Watts at 4 Ohms, I will be in the 100 Watt class for my compitition. Well If I can take that same amp and speaker and change the wireing to make it double its power I am still in the 100 watt catigory, but now I have doubled my power output.

I know the 100 watts was only used as an example. This is the reason I believe there are so many different SVC, DVC, QVC on the market.
