Does anyone know if the L100t3 and L80t3 use the same crossover?

Yes (no).

Would you care to elaborate? I want to find out if they're interchangeable.

Yes, I know, because Google is my friend, and no, they are not the same.

Interesting, how a change of woofer telegraphs up through the whole network.

Thank you. The diagrams are exactly what I needed. I want to help a friend with a pair of L100t speakers. He wants to hear the difference with the t3 crossover.

Since I've never owned either speaker, I have no idea of the differences, but people on this forum seem to favor the t3 crossover.

If the idea comes up to build some networks following the schematics, the DCR's of the inductors is going to be important, and I don't know where that information is.
