Here are some pictures of the driver I used. It is made by Lambda Acoustics and is model number 10001-PFPMF-6AF. You can follow the links to find out more about Lambda and their products. These are hand assembled drivers. As you can see in the pictures there is visible glue and space between the dustcap and the cone. Nick (the owner of Lambda Acoustics) has stated that I had nothing to worry about and that the epoxy they use will hold, guaranteed. He stands behind his product %100 above and behond the already impressive 3 year warranty. Nice to hear.
