I would say that tri-amping is a bit overkill, there is really not much to gain. Bi-amping is a must and so is DSP for correcting the frequency response. The passive crossover mid-tweeter may be given different slopes, moving the crossover point a bit higher. The 2 Ohm ribbon often need to be reduced in level, at least 1 Ohm or even more in series with it. Then you have 3 Ohm or more up there. Have you checed that your mids are in good shape, that the double-sided tape is holding teh Mylar? I prefer to have foil conductors on the mids. It will lower the output a bit and therefore you need to reduce the level of the tweeters (and raise their impedance...) even further. I would recommend at least 100 W/4 Ohm for the mid/tweeter section.
