welcome into Thiel's family, you will be pleased by your "new"fantastic 3.6 as I daily do.
If I can, and whether you plan to keep these jewels for long time, I suggest to purchase some strategical spare driver as I did, one tweeter and one mid, they are the most critical parts in this wonderful project and the "real" original drivers start to be very hard to find due to the poor stock available nowaday, furthermore keep in mind that only the original part number will assure the sound performance as intended by Jim Thiel.
