"rockport altair's and i can tell you without hesitation or any doubt at all that there are no box vibrations."
Of course they do not vibrate. They have a big hole in the back You did not find the bottom since, being a ported design, you do not have much of it. Having said that, it does sound like the YG do not have a high-pass filter on the mids. Not very smart and quite a bit of money for what is basically a 2 way with a sub.
