Hey guys

There is a pair of beolab 6000s for sale online near me (yahoo auction). They are being sold as broken. I have contacted the guy and asked for more info. They are working. They power up and play fine at low volumes but when the volume is increased there is a 'detoriation' in sound quality. He says it is like an electric grating noise.

Does anybody have any ideas what this issue is? I may just pass on them but I am skint at the moment (uni is expensive here). I don't mind paying for repairs but don't want to get stuck with a blackhole for money! He can't check the speakers themselves as he doesn't know how (?).

Yeah, that was my first bet. Any idea of the cost of a repair either buy myself or from B&O?

B&O only cahrges $120 for the set of 4 woofers. Easiest thing in the world to fix. The hardest part? - getting the fret off. 😂 

At that price its not even worth your trouble to refoam.

Although, after replacement, you need a signal generator and an oscilloscope / AC voltmeter to calibrate the driver levels. But if the speakers are for your own use and you don't care about the frequency response possibly being some dB off, well.. you don't care and just forget about it.

There's also the possibility of the speakers having some other faults. But if both of them are the same, it's probably this usual case of cone surrounds having split.
