Default Noise out of single speaker

Hi guys - I have a tweeter (Dayton nd16) that makes a noise I can’t figure out. My first thought was that it was blown, so I replaced it, yet the noise is still there. It sounds good at high volumes but at quieter parts of songs you can hear a distinct crackle out of it. What are some thoughts on possible issues? Bad amp channel? It’s run off a Rockford 360.3 dsp as well.

Thanks for any thoughts.

Swap the channel for the other tweeter at the amp (important), if the noise swaps sides itís the amp, if not likely a bad connection between amp or the speaker lead getting earthed somewhere

I’ll do that. I noticed last night certain parts of certain songs can mimic it, and it will be the exact same “pattern” of noise each time that part of the song plays. Some songs it’s very quiet or non existent. Would you expect that to be the case with either of the above two possibilities?

What's your HPF set to on them?

Do what has been suggested to help narrow the problem down.

They are high passed at 5,000. The left tweeter makes zero noise like the right tweeter though so I can’t see how it would be filter or gain related. I could be wrong there though.

That should be a fine HPF for those, did you every run them lower with a decent amount of power? It's possible that it's damaged, but the swap the wires at the amp, and you'll get some good info. It could be a bad tweeter, amp channel, wiring, etc. Seeing if the noise sticks with the same tweeter after swapping wires will tell you that it's either the wire or tweeter.

Makes sense. My initial thought was a blown right tweeter, but I replaced it with a new speaker and the noise was immediately still there so I’m thinking I can eliminate that possibility at this point.
