While it is true the load an ESL panel poses is a capacitive one, it is not necessarily accurate to say that Sound Lab impedances vary as widely as you describe. The step-up ratios of the transformers differ so as to reduce the impedance range an amplifier would face with a single step-up transformer, to make the amplifier load a more practical one. The impedance dip in the crossover region is largely due to the different step-up ratios, which is more challenging for some amplifiers. If a single step-up transformer proves practical then perhaps it could be offered as an option, although I wouldn't bet the ranch on it.
