Excursion damping bandwidth?


Wayne, are there any general rules as to how big an area the damped excursion works - in other words, over how big a bandwidth does the port reduce excursion &/or assist the woofer? & where is the Helmholz resonance/tuning frequency in relation to that bandwith?

I probably shoulda figured it out from your post, but I'm not sure I 'get it'... :-(
