    4khz for a tweeter? That's pretty high. Most tweeters can play comfortable 3.2khz upwards on a moderate volume level with the more engineered ones going lower especially large-format tweeters which has a more robust voice coil and magnet structure.

    The higher your tweeter HPF, the "safer" it is for the driver.

    Red_one presented a good post. However, I will remind car audio folks that the only time you damage your speakers - whatever driver it may be is when you drive past its mechanical limits. That's only the direct cause of damage - the others are simply causal relationship. For example, give a subwoofer a 10W clipped frequency, it won't even be damaged even if the waveform has a lot of energy inside. Why? Because the voice coil can take the punishment.On the otherhand, a tweeter with its smallish 1" VC won't.

    Yep, according to Polk Audio website, that's the frequency range of their DB line of tweeters (DB1001). Since I'm looking at ditching the passive crossover unit when I finally go active, I had to read up on how to keep the tweeter as "safe" as possible.

    Thanks!
