Hi James
I am re-reading and thinking about some of what you said:
---------------------------------------------
James Davis said in part:
Distortion essentially only occurs when the Xmax is being
exceded.
----------------------------------------------
This seems to me an over simplification, and not true. I mean
there are many causes of distortion which are not directly
connected to the over travel of the x-max. Subwoofers tend to be
distortion heavy devices. I mean they are not infinitely stiff,
infinitely light, nor do they accelerate or decellerate without delay.
But I don't want to go off topic into drivers just now, interesting as
that is.
I would very much like to better understand what causes
distortion in standard enclosures. For instance, in a port
enclosure, below resonance, the woofer is uncontrolled right?
Whether xmax is approached or not, there seems to be some
funky stuff going on. Also the stuff coming out of the port, how
clean is that?
James
