Home Speaker Asylum

General speaker questions for audio and home theater.

Good description

Nice job. Phase is not easy to describe in plain English, much less phase between two drivers.

I would simply add that the points you made about non-perfect devices applies to all systems, not just first order. First order is just more difficult WRT taking the compromises into account.

For those who might like to see a graph, I've linked to a first order Butterworth response of theoretically ideal drivers, 90db each. Red is lowpass, green is highpass and blue is summed response.

This is the minimum-phase response, no excess-phase.
