Oh man!!! I like this read already. Great post!! Crossover points directly correlate NOT just to what your speaker can play but location, baffle design, and distance from the other speakers as well. In car audio...NOBODY EVER FIGURES THIS CRAP OUT!!!

But it really is simple. I'm gonna go read this now. I know it's something I've already looked over but there might be some nice info in there somewhere

I will say this...at the end of the day you can read all the tech docs or theory you want but unless you can some how measure the performance of your speaker or convey what you "hear" into fix this or move that, you're still flying blind
