[QUOTE="ciaonzo, post: 8654792, member: 607015"] This is false. Simply sending low frequency content to a tweeter will not cause it to die, even with a decent amount of power. I'm not saying it will sound good, the THD would be quite high if the driver is not designed for low frequency use. Yes, low frequency content can and will destroy a tweeter, especially if it's not built for it. But it's not the same thing as saying if you cross high enough you will not blow your tweeter, which is basically what you've indicated. I have video proof of a Vifa tweeter being subject to a true unfiltered 50Hz sine wave, stroking it for all it's worth. The driver suffered no damage and is still in use today. You can very easily destroy a tweeter that has been appropriately protected from low frequencies in a mechanical and thermal sense. Even if you've crossed at something as high as 5kHz at 24 dB, if you send enough content and power to the tweeter above 5k, it will still die from a thermal perspective. There's not escaping the driver's inherent ability to dissipate heat, doesn't matter how that heat is generated. [/QUOTE]
