Need to fix my Infinity Modulus II center speaker, help?

So in 2006 I bought my HT system and with it I bought an Infinity Modulus II 5.1 kit. I love this set. Not only have I put it through serious "work-outs" with our parties and movie nights while they still sound great, but I still think they look awesome in 2013.

Recently I burned up my Onkyo receiver and I upgraded to a TX-NR717 which has a better self adjusting processor, 2EQ. The system reflects an "ERROR" on the center speaker and now that it did I have been able to notice the high frequencies are not all there on the center speaker. Years ago I left the grill off and my then 3 year old pushed the center twitter in and since then the bent bubble has cracked and fallen off so I can see the metal of the twitter.

Is this center speaker fixable?

Here's my issue, just in case someone can give me tips:

Like new.

For Modulus owners, crossover was $19 and the tweeter was $18 (bought 3 just in case).
