I have 2 Rockford Fosgate HE2 10 inch 800 watt peak subs that are DVC. one is wearing down and the other is in perfect shape. i was considering replacing the one that is wearing down with another one. I am in need of suggestions on what i could replace it with as the same subs are quite pricy.

How is the old one wearing down? While yo can mix and match subs you will want to try to match the t/s parameters as close as you can. How much power are you applying?

HUH???? I have never seen anything like that.

Are you sure you have polarity hooked up correctly?

Take a AA battery. Place the positive speaker wires on the + of the battery and the negative speaker wires on the - of the battery.

Both cones should move out.

It almost sounds like you have either one wired out of phase, or have a coil of one wired out of phase on the old one.

Are they in a common chambered enclosure? (both subs share the same box with no divider) that can cause that effect visually.
