[QUOTE="BenH, post: 8864724, member: 690429"] Thanks. What I meant when I said I don't understand/think shimming is needed is that the internal cone does not shift around at all. Because of this I don't see how removing the dust cap would have helped because the cone could not be shifted around anyway. Maybe I'm missing something in my understanding, but if the shim is used to help position the cone to center for setting, but in my case the cone didn't move anyway?? So the main reason I was trying to repair instead of replace (in addition to cost) is the form factor of the OEM speakers. With the model that you guys suggest, how am I supposed to mount those tweeters? As you can see from my pics in the OP, my tweeters are in a custom housing bracket which sits right above the woofer. I don't think that a different tweeter will fit in this housing (not even sure if I can try to take the current ones out without damaging the plastic housing). So where am I supposed to fit these? I talked to someone at Crutchfield about a similar model and they seemed to infer that they came with small brackets that I could attach somewhere else. The problem is that the rear deck (top of back seat) has limited clearance and grills built in for the current speakers. Going with a system like this it sounds like I will need to find some area where I can drill into the metal of the rear deck to mount these and hope I have clearance under the top? I'm looking for as much of a drop in replacement that I can - in terms of modifying the vehicle. Also, could you explain what that box is that comes with the unit? Is that an optional piece? Apparently the issues I'm explaining on this 2007 car have been around for many years.
