    i fried the tweet a year ago. there are a couple other threads i've seen today about disabling tweets, but i'm wondering if anyone knows anything specific about this cab - since i destroyed it by accidentally having the output on a distortion pedal too hot.

    the impedance load my amp sees will not change, right?

    and i'm only missing the highest high frequencies? i didn't like the horn anyway, but now o wonder if it's not cool to have the damaged circuit / tweeter in use...

    I have a Powerhouse 610, and I've disconnected one of the tweeter's feed wires at the tweeter itself a couple of times, and it didn't hurt anything - and wouldn't change the cab's impedence... In fact, to me the cab sounded better with the tweeter totally disconnected than when connected and it's level turned all the way down... I ended up hooking it back up, as I preferred having it on in a band setting, but those are my experiences on the subject...

    thanks.

    so how 'bout this:

    if you blow a driver in a cab - like really fry the driver, will the amp see the same impedance in that case as well?

    No - that'll definitely change the impedence...

    In general, yes. But not in the case of a tweeter fed by a crossover. Below the tweeter crossover frequency the amp just sees the impedance of the woofer (assuming no midrange). For example in a 2-way design with a 2Khz crossover frequency, assuming both woofer and tweeter are 8 ohms nominal impedance, below 2 Khz the amp essentially sees the 8 ohms presented by the woofer, and above 2Khz the amp sees the 8 ohms presented by the tweeter (correct to a first order). It's a bit more complicated in the crossover region, but for all practical purposes, that's the way to think about it.

    i just want to be sure that while i run two 8 ohm cabs, one with a fried tweeter, that my amp is experiencing a 4 ohm load....is this the conclusion we have come to?

    thanks...
