Hello,
Have you ever seen a pair of beolab 8000 mk2 from after 2005 suffering of foam rot ?
i have already removed this foam issue from several mk1 and was ready to do it on a mk2 of 2006/2007 and I wonder if it worth to do it. The system on the top of the fret is quite different from the mk1. The top aluminium cap is screwed.
4 beolab 5, beolab 9, beolab 10, beolab 5000, beolab 8000 mk2, beolab 6002, beolab 3500, beovision 7 55 mk2, 2 beovision 11 46 mk4, beotime, beosound ouverture, beosound essence, beoplay A8, beomaster 900 RG de luxe and the collection continues...
I wasn't aware that BL 8000 speakers were susceptible to this problem. I still have a pair of MK1 8000s from 1993 that still seem alright, other than a bad standby transformer that needed replacement in one of them.

I can't tell if he's talking about foam rot on the drivers, which can't happen as the driver surrounds are rubber, or rotting/deterioration of the foam inside the speakers which can damage the power supply board, which I've read about before here.

I'm afraid I'm recovering from the BeoVirus.
Foam inside the speakers around the amp and power supply not the foam of the driver.
if you have never remove it from your mk1, you'd better do it. It will attack your pcb.
a b&o tech told me that he removes it each time.
i just wonder if someone saw this issue on a mk2 pair.
