TEKTON IMPACT MONITORS

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?.....

Mission honestly the impact monitors gave me a lot of good listening moment, regardless of how they are design or not, It is still not a mistake of owning them, because I like the sound and looks too. Well to get a nice cabinet you have to pay more. I got you , Audiophile are still buying them , so it means they like them, they even wait for months.

even a single stereo volume controller, whatever it may be, has to equally attenuate each channel individually. Just because it’s uniformly controlled by the same physical device, whether it is by reducing it through resistance, or another form of control, every channel will have an individual and distinct attenuation.

Two channel or home theater multi-channel, each circuit is actually individual - unless it’s mono.

I am not saying I am right, in that I have absolutely solved the issue. It may be a bad valve, it just seems that when you changed the volume, the issue wasn’t attenuated along with the volume, it corrected it.
