Re: Crossover design theory - planar speakers special?

I learned two things from my recent work on the MG1.6 electrically flat crossover . First, the crossover didn't sound right until it had both flat on-axis response (considering phase) and flat power response (not considering phase). I think that achieving flat on-axis response is only half of the solution - since the planar radiates sound in all directions, the driver's ouputs undergo large phase shifts relative to each other at different locations in the room, and thus its important to consider the total power output of all drivers in order to get the room response right.

The second thing I learned is that the QR tweeter doesn't appear to be as resonance-prone as I had thought (not sure if this applies to the true ribbon).

I've been listening to the MG1.6 electrically-flat crossover for two weeks. It gives the MG1.6 a neutrality that the stock crossover lacked. The stock crossover's slightly recessed midrange gives the impression of more detail and greater bass extension, whereas the electrically-flat crossover is smoother in the midrange but weaker in the bass and very top octave. Which voicing is "better" is strictly a personal preference.
