HELP No sound from tweeter.

Is there some sort of fuse protection? You never specified you model. If that's blown that could be the problem and easily fixed. You can get a new one at radio shack. Worst case efforts on your part (not much): take the tweeter out if possible and peek in cabinet to see if any wires may have come loose. If its not a fuse, or a loose wire, or a damaged/blown xover part, its probably blown. You could take the tweeter out and hook it directly to the output of the amp just to check, bypassing the xover. (this would mean snipping the 2 wires, no biggy, crimp them back to the main leads when done with some connecters from radio shack, $1.49 for eight). Just play some material that you know has no low frequencies for awhile into the tweet and no damage should be done as you check. Or it may be time to upgrade to some new speakers? Use the remaining one for a center channel? I don't know the speakers but a tweeter change is possible, not always, although you'll want to change both.

If the tweeter's not fused (likely) then it's probably blown. Your sister probably blew it by driving it into distortion with an underpowered amp or receiver. But since you sold them to her, it's definitely your fault!

I'd contact the company and obtain a replacement tweeter. If the speakers are still under warranty and you send it to them, they may even repair it for free.

Next, you need to get your sister a more powerful amp if she wants to continue playing the speakers that loud!

Happy New Year!

Thanks Cornfedboy. I've since swapped out one tweeter with the other and have determined that I've got a bad tweeter. I'm having trouble finding a local dealer since MS was bought out. Also, the MS website doesn't help much for those of us out of the UK. This s**ks!

Im not sure but I think MS is now owned by Creek. Anyone know? If so try to find a Creek dealer.

Many manufacturers of speakers buy off the shelf components from several excellent raw speaker companies in europe. If the speaker is labeled on the back as to its model and manufacturer, you may be able to easily purchase the replacement from one of the companies catering to the do it yourself speaker builder which usually carries these lines such as madisound in wisconsin. Good luck.
