TEKTON IMPACT MONITORS

This morning while Iam listening to my Elac B6 Speakers, while the cd is playing   I heard a familiar scratchy sound on the impact monitors, I raise the the volume and the scratchy sound went away, hours or a day later the voice coil fried.Iam thinking of bringing the amps for a check too.

Are you using a pre amp?
What, or where is the volume controller in your system?
It's kind of unusual that by raising the volume, you reduce a bad noise, that might be an indication of the volume attenuator introducing noise.

Have you checked your volume device, if it's the culprit, you can possibly clean or just outright replace it with something better?

I doubt it’s preamp but I will check, could be tubes on my amps, I can hear the scratch noise on the right side only.

I bought for replacement, I stick on the same tweeters, I bought six, my technicians upon looking at the tweeters said the tweeters don’t have rooms for heat, why the the voice coil burn ,I remember playing them 6 hrs straight that day, volume on the 10........the tweeters,dont have room for heat?..you think that goes back to the point the tekton cabinets are junk or at  best poorly designed which is ecactly what i saw when opened up ....and if playing a speaker loud for hours causes failure, from heat and poorly designed cabinets who would want them?.....
