Possible issue with Terminal: speaker crackle
Has anyone ever heard of an issue with the Marantz (or AVR) where a speaker terminal puts out a partial signal during impact sounds? My right speaker's tweeter occasionally crackles on impact sounds and is generally quieter until I re-seat the speaker-wire.
I have a Paradigm F75 tower connected to a Marantz SR7010 and I have crackling in the tweeter fairly infrequently (the worst type to troubleshoot). It generally happens on impact sounds where there is a spike in volume. It could be the speaker wire. I used 12 gauge monoprice wire with Sewell deadlock banana plugs. I moved to those from regular monoprice plugs and it seemed to fix the issue for awhile.
I was getting crackling noises with those. So I went to the Sewells and that fixed it. Then it happened again, so I cut the Sewells off on both ends have have a direct connection (no plugs). So it's AVR to speaker with no connectors. This fixed it for one night.
But it happened again!?!?
So I had a pre-terminated wire from Sewell and plugged that in. Fixed! But I'm not confident it won't happen again.
Is it possible that there is damage to the speaker that infrequently has the tweeter crackle? It's not the mid-woofers (or at least not noticeable).
Is it my AVR? Any ideas?
Further testing options
1) swap the right and left to see if it's the AVR. It only happens on the right hand side
2) see what moving the speaker wire does (more methodically, reseat in AVR, reseat in speaker)
3) use a new pre-terminated wire (in the mail)
