The good news is that you don't need a separate amp to drive the DWM! Basically what you do when using the DWM's with the MMG's is to feed your two channel amp to the DWM's inputs, then the DWM's outputs to the left and right MMG. This feeds the MMG's off the DWM's internal crossover.
The clever thing that makes this possible is that the DWM has two separate voice coils, so a single DWM can handle both channels.
I still haven't head the DWM's, but when I had MMG's I used them with an XPA-2 and it was an excellent match. I imagine you could also use the XPA-3 arrangement using the USP-1's bass management. In that case, you just hook up one of the inputs of the DWM.
