Didactically...I think we are supposed to be talking about the main speakers of a setup using a subwoofer (or two). In this context a spec of 80 Hz vs 100 Hz is not a big deal, especially because the pricing structure of these two speakers from the same maker suggests that the difference is probably only in the published numbers.
You certainly may stick with your opinion, in fact you are stuck with it!
