I've always suspected that such a system may take several cycles to build to full excitation, and possibly delay over several cycles. If so, this may lead to sharp transients being less well reproduced in a ported system. |
Ilkka has measured this with a ported sub with port open and port plugged. The delay at tuning frequency is definitely not o the order of several cycles, see
here. The difference he measured at tuning, where delay would be highest, was less than one cycle. As tuning frequency gets lower and lower, I see this being less and less of an issue due to sensitivity at infrasonic frequencies and the actual tactile effect. As an example to test, try playing a 10hz sine wave for only 0.5 seconds and see what kind of an effect you get out of it
I definitely agree with you on this opportunity though, it is about as ideal as it gets, and I'd encourage as much testing as can be stomached.
