I REALLY don't recommend this project.

Recone parts are NOT available for the woofers.

Any reason you want these?

The Santana is not highly prized.

I mean a decent pair just sold for under 200.....

The 15 sounds good. The tweeter is easily blown. Replacements are not available, and the woofer has to be reconed typically as a 416...

The tweeter isn't Altec it was purchased from CTS.
