Oh no! Here we go again...

Look at what you have done Knu!
You can definitely leave one coil disconnected. JL will void the warranty if you do but not for the reason cited or because of driver failure because of the wiring method. After numerous e-mails between the JL tech support manager and myself, we came to an agreement that it would not hurt the speaker if used properly. Meaning, halving the power handling, re-measuring the specs and then using the correct box for the new parameters. Unless of course you short the other coil which just results in a 3 dB drop in effeciency. Cone travel is not limited, if you only send half the power, the VC will not get hotter, it will function the same way as before with lower effeciency and potentially different t/s parameters. It will not make the subwoofer work harder to move the cone. But it will have to work harder to produce the same output because of the drop in sensitivity.
Now, to add to this slightly, there are very few circumstances where using 1 coil makes sense, so normally, I cannot recommend this method.
Yes, I have used a DVC sub with only 1 coil connected and in my scenario sounded very good and caused no damage to the sub.
