I'm installing some Elevation Audio Concert comps. All the polarity is correct, they are being powered by a JL 300/4. My problem is that my tweeter has no sound. Also, for some reason, it seems as if the midrange is playing almost a full range (dont see how, but thats what it seems like). Anyways, what could this be? The polarity on the tweeters is good. I have a HPF set on the amp at like 75-95hz. No other filters are on.
