All Mackie SRM1801 subs which pass through our workshop have a major rework and upgrade. When working, these subs sound fantastic. Deep rumble and thumping bass. We have identified a number of common problems which we address on all the 1801’s without exception.

So what do we do?

  • Rework of PSU and output stages
  • Replacement custom 18″ LF driver
  • Fitting of foam trim to stop any unwanted rattles
  • Fitting of our custom driver sub-board to output stage
  • Modified over current protection resistors
  • Replacement driver IC to latest revision
