Hi Steve,

I'm very sorry to hear about the damage - the dot-matrix versions of the DSP6000's are pretty rare beasts!

You can swap over the rear panels between the speakers but if you are swapping between 7-segment and dot-matrix displays, you will need to change the firmware. There are two versions for 24-bit DSP boards, one for 7-segment and one for dot-matrix. Just obtain the correct version (I'm sure a friendly HH dealer can assist) and load it into each speaker. You'll probably have to swap over the entire back (both lower PSU part and upper electronics part) as they changed the PSUs between versions (the later versions are more like DSP5500's with just the transformer on the lower plate.)

If the cabinets are damaged beyond repair, then it is certainly worth salvaging the boards and driver units, or at the very least putting the damaged speakers up "for spares or repair" once you've swapped over the rear panels!

It is also worth getting the amplifier boards re-capped if you can, as this will make them sound as new.

Good luck,

Steve
