Ok, maybe this is a dumb question, but i searched and couldnt find the answer...although, I didnt know what to ask, which may have hindered my search.
My question is, take a woofer, say, scanspeak 18w8535, in a 40L ported box. If the port is set at 1", the resonance according to unibox is 3813hz. If I am crossing the driver over at 2000hz, does this resonance matter? How would this effect the speaker, if at all? According to unibox, it would pretty much be a flat response to 30hz.
I guess the question is, if the port resonance is above the crossover of the woofer does it still affect the whole speaker?

Depends on the roll off your using too. Also harmonic distortion can excite resonances.
1" is fairly small, I would review teh port speed at maximum excursion. Port chuffing in this case will be more audible than the resonance.
