If they implemented it that way, the user setup for it would have to be very complicated to offer any value - speaker crossover design is not simple. I know that I don't have detailed specs on where my speakers' crossovers are set or at what slopes they work. Even if I did have that information and the software allowed such a detailed level of control over the crossovers, putting two crossovers in series is undesirable - meaning that you'd need to go in and remove the crossover network from your speakers for this feature to work (or at least part of it, if you have a 2 1/2-way or 3-way speaker design). How many of us are actually equipped to use such a feature? Conversely, how many of us are equipped to make a complete mess of things using such a feature? (I'm holding my hand up for the latter question, even though you can't see me...)
