200W Digitech PA speaker repair

Need Help with fixing your device?

For years now, I have been getting requests to help with repairs of equipment, in particular about the Novation Launchpads. I do try and help where I can but I want to share the information and experience that I am giving out. I have come to the conclusion that I need to make a platform where you can submit your problems and repairs. The platform is Fix My Stuff and is currently under development. Check it out and sign up to get notified when it will become live. If you’re a web developer/designer, please help or review the platform. Any problems email me at tinkersprojects@gmail.com.

I picked up 2 of these 200W Digitech PA speakers from a warehouse sale for $20 (RRP $399) each. When i got them home I discovered that on a crossover had been blown up and the other has interference/noise going through the amp. Taking the crossover from the interference speaking and replacing the blowing one, I got one of them fully working. I’m going to look into the other when i have time.

The designs  of the speaks are very poor and was bound to have something in there blown up. The interference speaking may have a blown transistor or power supply capacitor (giving 50Hz noise). I would not spend $400 on a new speaker but $20 is not bad to get some parts from it.
