vc question

[04silverz 10+ year member]

no one on sounddomain knew or answered so i guess ill ask here

i know that if you have a dvc sub and one coil blows you can still use it. basically, the way i understand it, the only thing would be that the t/s parameters change.

my question, and this is just pure curiousity, is if a sub is made in svc 4 ohm and dvc 4 ohm and the dvc blew a coil would the t/s change to the same as the svc? or does it not work that way at all? would the dvc just go to some random specs? and if you had multiple dvc subs that blew a cingle coil would each sub have differnt specs or pretty similar to each other?

again this is just a thought that i came up with while driving and not something im intending ondoing.

you know what they say...courisouity killed the cat //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

That's a good question, I haven't really thought of it much. All I know is that a DVC sub run off of only one coil usually doesn't work very well.

right

but from what i understand it would sound different bc the t/s changes and since theres differences from the factory between dual/single or 2 vs 4 ohm

i was just curious, i alwys have questin like this pop up but usually forget them before i have a chance to ask anyone

NO!

A SVC and DVC are basically the same. There is a slight difference, but its not audible. The T/S are different but much of it has to do with constants that are calculated using the T/S which DO remain the same. The reason there are DVC’s and so fourth is to get the impedance just low enough to maximize output from amplifiers.. that’s the only reason.

If you blow one of your coils in a DVC subwoofer you'e driver is shot! Basically if you continue to use one of the coils, it its like running a sub at 30% of what it could do and it completely changes the way the subwoofer behaves. The box it was in is also probably no longer applicable and you have greatly reduced the output and power handling of your driver. The DVC coil is like two SVC coils that are each about 1/2 the length of the SVC. So if you blow your DVC you basically have 1/2 of what you had in your SVC, not only that you have a dead conductive coil that plays havoc with the active coil, not to even mention the extra weight of the dead coil doing nothing to your system but making it inefficient.

If you blew a dual or quad coil, you need to recone it.

That's what I was thinkin' //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Depends on the application.

Heck, that's exactly what the Ascendant Atlas subwoofer was....a DVC subwoofer, but you only powered a single coil and used the other to adjust the Q. This can be done with any DVC subwoofer, and if used in the proper application can work very well.
