Center Speaker crackling sound in Marantz SR5006

[rpradeep]

Hi Friends,
Owning a Marantz SR5006 for the past 7-8 years. Paired it with KEF Q series. However iam facing a problem that while playing the movies, the KEF center speaker makes crackling noise( and removing the center speaker cover, i could see the kef bass driver moving )... This occurs at all times while playing the bluray..It initially started somedays back with hissing sound in the center speaker, now to the crackling sound.. I tried to swap the other speakers, but the issue still persists, making it very clear that the issues is in the SR5006 side..
Any advice how complex is it to fix this in the service center?
Kindly advice please..

Regards,
R.Pradeep

This thing some times happen due to rusting , moisture, dust accumulation, loose jumpers or contacts etc in avr. Better get it service for cleaning purpose. After some time it will either blow your speaker or blow your amplifier channel.
