I was going to ask what brought you to Arizona, but then realized all you Canadians invade during the Winter. Andre, you'll have to let me know the next time you're in Arizona!

So if a speaker shows a resonance at 40 or 50 Hz, it's hard to know if it's the speaker or the chamber. This seems evident in those waterfalls, at least for the speakers that play down to 60 Hz or lower.
Ethan, I find this intriguing. I've always heard about port resonance and experienced it myself with my Rokits, however, this account confuses me.
How would you get port resonance under 100 Hz from a porthole? These holes are much smaller in surface area than say a Helmholtz resonator tuned to such frequencies. Most portholes are roughly 2"-3" in diameter which would suggest port resonance happens much higher in frequency like a couple hundred Hz or something.
I do hear strong gusts of air coming from ports when monitors play low frequencies like 50, 60 Hz as it needs a lot of air to move the speaker - is this actually what is referred to as port resonance? I don't really see how this can be "resonating" - it stops the second the sound stops.
