all i can say to ninja is that we all have 30 days to basically try our speakers inside out. if you still like them after 30 days they are yours to keep. if you don't then you return them. that puts all of the math to sleep. by testing a product (m80ti) that is no longer made makes no sense. please send me your first crossover and i am sure that i will find issues. I am sure that you probably fixed it. now as for the tweeter issue, there is none. I have tried at least 5 different companies before settling on axiom. its all about the sound. the axiom were the best for my money.

PS do you give 30 days to try your stuff?
