View Full Version : UBMBP 17" Right Speaker Distortion Query

Hi all,

At certain frequencies I find my UBMBP right speaker when volume is above the half way mark generates a distortion noise similar to that of a damaged speaker in a pair of iPod Headphones.

The flaw is best show with a frequency sweep test:

Could any owners of UBMBP 17" turn your volume up to 90%+ (Yes I realise this is loud, but it makes the problem more obvious) and run the frequency sweep from the link above?

I'd love to know if this is 'normal'. A quick google of the problem seems to indicate there are a few others experiencing the issue, however, as the 14 day period is fast approaching, I'd love to know if this is indeed a fault to avoid 'repair hell'.

Thanks everyone!

-Steve.

not entirely relevent, but the mbp 3,1 17" has no such problem. not sure if that is any help to you
