I'm not exactly sure. Maybe it's not the tweeters but the crossovers? I actually hooked them up to a Marantz amp running at 150wpc which is within the ratings for the speakers.
After I did that for awhile, I got a new receiver and ran the Audessey setup without the amp, kept getting speaker errors on both OM-14's. So I read up on possible causes which point to tweeters. Ran CD with high frequency tones and sure enough nothing out of either speaker.
Just to test the receiver I hooked up another set of older bookshelf speakers in place of the 14's and completed the Audessey setup.
I keep asking myself that same question though, how in the world did both tweeters on each speaker go out at the same time?
