I had a similar sounding problem (literally) although my tweeters Did still work. I had narrowed it down to the crossover, But instead of just sending me a new crossover as I had requested axiom decided to send me an entirely new speaker and paid to send the broken one back.
Im not sure how axiom will remidy the situation but I expect that from my past experiences you will have it fixed by the time your calibrator comes by.
That's reassuring. Thanks for posting your experience. I'll be sure to keep everyone posted on my progress in case anyone else runs into this problem.
