Maybe so, but three of my favorite speakers have bass crossovers you say include bad engineering practice. This Focal, the KEF 207/2 (crossed at 120Hz), and the Revel Salon2 (crossed at 150Hz). I will say this, after all of your lectures on subject, when I'm reading the specs for a speaker one of the first things I look at is what frequency the bass crossover point is, and I think of you.
