RE: Maggie 1.7: active XO + bi or tri amp??

I wouldn't call it a 2.5 way crossover. It is actually a 3-way crossover, but with a rather weird alignment.

The "supertweeter" element is just a single up/down run and the resistance is only 1.3 ohms, so it probably doesn't make sense to separately power it.

There's a shunt capacitor across the regular tweeter element which you could leave in place, and then remove the large capacitor and inductor forming the woofer/tweeter crossover. The bi-amping scheme would be much like an MMG or 1.6 then. Very straightforward.

Dave.
