Been looking for awnsers for years. No concreate awnsers. What is the difference between the txx apa 12 txx apc 12 txx apx 12. I have seen them all right infront of me. The apa has a smaller coil than the apa. But the coil size listed nothing changes on any of them. In any color

Have you compared the entire Thiele Small parameters for both drivers?  You say nothing changes colors? Are you asking visible differences when looking at them?

And good luck getting proper t/s for audiopipe anything...  Not really a reputable company.
