Symptoms;
While playing music at low volume a scratchy noise builds up mainly in the middle speaker, however increasing the volume to around 50% and then back down reduces the scratching completely, but it slowly returns in about 20-40 seconds.
When I push on the middle speaker when it is turned off, but while the speaker is attached, I get a crackling noise from it, the tweeter and very low noise from the sub.
When I push on the middle speaker when it is NOT attached, there is no noise.
I have swapped the mids around and the symptoms travel with that speaker.
Clearly there is something wrong with that mid speaker. I'm stumped why pushing it causes it and the other speakers to make a scratchy sound and why it doesn't make any scratchy sounds when unattached.
This is what they look like: https://gitarownia.pl/product-pol-8516-Wharfedale-EVP-X215P-para-uzywanych-kolumn-aktywnych-400W.html
Any ideas what could be the cause and how to repair it if possible?
