I did hook it up.
Well, actually, I swapped out the bass and mid/treble in the biamping setup first, so that my Classe CA-200 was on the bass and the Krell KAV 250a was on mid/treble duty. The Classe is rated down to 2 ohms although it doesn't double into it.
Without the DWM's resistors, it sounded horrible. The Classe lost all control of the bass and it was just one big boom, no matter the level set on the crossover.
Add the resistors and it is an entirely different story. Much of the clarity of the bass is restored and the speakers just sound a little "thicker" and weightier. The bass panels are not screaming, just adding a little oomph. Still needs work, some tweaking, perhaps separate amplification and full range input (bypass the active crossover) for the DWMs, but I can see that this has some potential for an improvement in the Maggie experience.
The Classe has been playing for an hour now and isn't hot...
