"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.

Physics are physics. A ported design like the Alter, will be apprx 24 db down from its reference efficiency point at 20Hz. Like it or not, that is how it goes. Whatever low bass you are hearing, is in your head not in the real world. In terms of the V3, you can ck online and see how low they actually go. They have 12db more output at 20Hz then the 4 time more expensive Alter. It is not all about size and gloss finish you know. But again, if you live in your head, that doesn’t really matter doesn’t it? I have nothing against your speakers, I heard them few times and thought that other then the silly side firing woofers, that sounds completely disengaged from the speakers, they were actually very pleasant.
