I bought a pair of Pioner CS77 speakers today at a garage sale and I want to use the 12" AlNiCo woofers in another project. Is there any hope of finding the T/S parameters for these? I know any self-respecting DIY'er would be able to measure their own, but I'm not setup for doing it. Looking for the easy way out. :D

The drivers are marked 30-25F-2 (no vented dustcap). Any help would be appreciated.
