The drivers door speaker in my '07 Savana gave it up recently. I ordered OEM replacements prior to pulling the blown speaker. That was a mistake. The door speakers in my van are an upgrade or at least better than the OEM replacements.
The part # for the existing speakers doesn't match the # for the new OEM's and doesn't return when searched on Autozone's site.
I returned the replacements and ordered re-suspension kits from:

This was a much cheaper alternative. The OEMs were $40/ea. The kit was $20/pair.
Mine is a stock sound system. Spending much on new speakers would be a waste.
I just reinstalled and closed up the door skin. Sounds as good as it's going to get.
If I put in a new sound system down the road new/better speakers would be on the agenda.
