Hi, Until my xs800h arrives, I am borrowing a Carvin DCM2000. This is a straight power amp, with my multi effects BP200 pedal as the pre amp. I read on another thread that lots of distortion and high levels of volume can break a tweeter. I have a Bag End cab with a built in tweeter inside one of the speakers. Question 1: How do tweeters work, and what are tweeters? Is there a way to turn off a tweeter or if you have a cab with a tweeter does the tweeter automatically play? My xs800h didn't say anything about tweeters, does that mean it doesn't use the tweeter? Question 2: Is there a way to turn off the tweeter? I don't really see any advantages of using a tweeter when I am playing very loud very heavy distortion other then the worry about it breaking on me. p.s. Up until this point I am staying away from heavy distrotion until I know how to avoid breaking the tweeter.
