Get familiar with the reaction system: Introducing the Reaction System

So for a system to be called linear phase, how long/ far would the phase need to be continuous before wrapping? From woofer LF roll off through 20K? Past x-o by???

I agree that linear phase may not be distinguishable feature, I'm talking about "labeling" a system phase response.

John H, thanks to JP I did get that email

The phase slope would never be constant in the mathematical sense unless the FR is completely linear/ first order. I've always thought that all single driver systems were linear phase even those that don't cover much FR.

So, for a 2-way as long as you don't wrap at the x-o would that meet the "linear" phase definition?

That's correct, Ed. The Linear Phase has to do with the relationship of the drivers in the design.
