You have a bad set of Audio output IC's for the sub. There is two of them. TDA7293 REPLACE BOTH!!!
There is 4 on one side of board,and 2 on other "also 1 small one" The the two are for the sub,the other 4 are for the main speakers/surround. They sell on Ebay for $6-10 each or a kit of all 6 for $25.

if you have still the problem, I got the solution from Kef USA. It is somewhat involved in taking the unit apart and replacing a resistor and capacitor. With the instructions supplied any electronic technician or TV repair man can do it in less then 1 hour. email me and I forward the instruction in PDF: Xxel_g@mail.coX . Replace the first X with a and last X with m in my email address.
