I have 2 DVC 12' subs in a dual chamber sealed enclosure. I wanted t
see how lound one could get by its self so I only connected one of th
subs to the amp. I noticed that when the connected sub plays, the no
connected sub moves also, but not nearly as much of coarse. Could thi
movement be soley from the vibration of the box or the spl inside th
car? It's made w/ 3/4 inch mdf and the outside doesn't seem to b
vibrating at all. it also happens at any volume. The subs are dual
ohm voice coil drivers connected in series (8ohm per sub) and the
paralleled at the amp connection (to a JL 500/1-internally bridged)

Now, I know alot of people would suggest the simplest answer to thi
problem would be that there is a leak in the box, or in the wal
between the two chambers. I have checked and double checked the box
There is NO leaks! When I push on one cone, the other does not move.

I read a few things about some behavior DVC drivers have when connecte
in series called Back EMF where the magnetic fields of each speaker tr
to modulate eachother. I don't really get it all, but could anyone els
explain, or would you think this could be a problem in my case? I'
pretty sure I connected the subs correctly. They both read 8 ohms
