RE: Summary article on importance of transients over pitch

I looked at the crossover of the Froy MTM 2 way and it is 1st order on the midrange/bass and 3rd order on the tweeter. The circuits in the midrange crossover are dedicated to flattening the FR and the impedance of the midrange. It is a series notch filter and and impedance adjustment parallel to the mid/bass drivers.

That attention to impedance probably gets the speaker to be in phase in the midbass to the top of the midrange at the 2.2 khz LP. That is most of the critical range and should give you what you experience. If you use the subwoofer at a low enough freq then you will have no phase effects in the critical portion. In a 2 way, even an LR4 has no phase well into the pass band.

In a bandpass the LR4 is truly vicious with the phase, running the entire 360 deg. from the LP to the HP.
