I never said that I "crossover" above 100 Hz, and I don't know where you got this idea. The only "crossover" would be at 50 Hz from the Summas to the VLF sub. The other subs don't crossover anything, they just augment the mains and simply fade away being down by about 6 dB at 100 Hz. with a very steep fall above about 120-150 Hz. So there is no potential for the things that you are ranting on about. This was all in my previuos posts, maybe not this concisely stated, but it was there. You seem to make up a lot of things that I never said.
