Pop/crackle in one speaker at only low frequencies in the tweeter

Odd problem here. I have some Silverline Audio SR 16 speakers which I just purchased used. They sound great. However I heard a pop (like what vinyl can do) when playing bass heavy music (not vinyl, digital served). I thought the subwoofer was rattling a connection as it did not sound like a speaker issue to me. I removed the sub and I thought it went away. Today I was running the stereophile test tones to dial the sub in at low frequencies. A pop or crackles appears in one tweeter at 50hz test tones and the few test tones below that. Nothing so far anywhere else in the frequency range but I have not been doing that much. I get the same pop/crackles thing with the sub removed and I play the tones thru just the monitors. It happens about 1/2 the time I run the test tones and only in the low bass area.  I did swap the speakers from right to left and the issue follow the speakers. I am running the speakers single wire and they have jumpers installed. 

Any ideas here?

50 hz for a tweeter? I don't think so.. unless you wired direct from an amp, with no XO.. The reason a speaker uses a crossover is to stop exactly what you're hearing..  If you're hearing it BELOW that you need to check out what is going on there.

60 hz and below is sub
60-250hz is bass
250-2500 mids
2500 up is tweeter or highs..

It sounds like you have a crossover problem. If you do, you might have a driver problem too. 

NO sound should be coming from drivers other than what the driver XO point have been set at.. 

So noise from the tweet, while doing low pass sweeps, is just as bad as 5k sweeps coming through the bass drivers...

Something is wrong.. look at wiring from the binding post to the XO give it the smell and a good visual.  Go from there.. 50hz signals getting through to a tweeter is not good though.. Snap, Crackle, POP, come to mind..
