Wilson Maxx II problem


I have a pair of Wilson Maxx II's that I have thoroughly enjoyed, until a couple of days ago.  I developed a crackle in one of my woofers.  The replacement cost is over $1K for the woofer.  I'm told, the woofer is specifically designed to the crossover, in the particular speaker, that's why I can't simply replace it with a used one, from another Maxx.  Does anyone have any suggestions, for a replacement woofer, other than shelling out over a thousand bucks?  Here's some component info:  I'm running krell KV-600 monoblocks as my power, and Aesthetix Calypso as my preamp.  The Krells are rated at 1200 watts into 4 ohms, which is what the impedance is for the Wilson's.  The Calypso tops out at 88 on the "dial", and I usually top out at 62, but the other night I went to 67.  I don't have a graph, but I would think I was well under 1K wattage.  I have always been told, that a driver can take a lot of power, as long as it's clean.  Did I simply put too much power in, or should I put an oscilloscope on my amps?  Is there another option, besides shelling out a thousand bucks, and still have the speaker match it's original specs?

Luckily for me, the damage isn't that bad. I can listen at normal to moderately high volume levels, before it starts to break up. I have as much time as I need, to research all scenarios.  I'm still waiting to hear back from Wilson, to find out how much power the speaker will actually handle. Once I get the driver replaced, sure don't want a repeat of the failure.  
I own the same speakers.
Don't mess around - send the driver to Wilson and get it checked out and repaired or replaced!  Might be a simple issue.....
I've learned a lot , although it be through other dealers who took time to talk to me.  The woofer is matched somewhat to the crossover network  I didn't really understand at first and being from Missouri,  I had to be shown or I this case taught.
