always check input and output, and use a test driver, not your best sreakers. :P

i always do, and ive mever blown a speaker.
If it aint broke, don't fix it. If it is broke, fix it.
If you can't fix it, take it apart and see how it "worked".

How do i protect my speakers from any other gc mishaps?

would just putting a fuse at the speaker terminals work? what sorta amperage?

btw, what couldve caused the speaker to blow. it was playin at low volume..
Have you checked what happened AFTER the fact?

Did you check DC offset and what did you get?

A fuse will not protect from DC, only from higher levels. Unfortunately the woofers are the ones to go when DC is present, because tweeters usually have a blocking cap.

What did you blow on your Kef? If it's the tweeter then you had oscillation or high level probably.

In any case I have not seen threads on this Forum that deal with the need to protect our speakers and still have a good sound.

thanks for the replys!

I havent infact checked the amp after the incident. I had to go away for a few weeks and now im back, looking at it again.

The woofer blew on the Kefs.

What do you mean by the DC offset? is it just the dc at the output terminals?

btw, i did test first with a crap speaker. The amp was running fine so connected up the Kefs. They were running fine for a hour or so until this happened...
