Rockport Technologies addresses cabinet vibration?

Joey is stating fact. Very different methods.

The PBN Audio Innerchoic line of speakers also does a nice job of addressing cabinet vibrations.

I believe all competent loudspeaker companies address
vibration and flex issues and work to minimize/control them. It just seems to me that Andy Payor of Rockport Technologies has taken this to an exceptional, but pragmatic level, in creating these Ayla loudspeakers that he designed to represent sota (state of the art) music reproduction. I think most forum members are not even aware this level of refinement exists; I didn't until very recently.

Yet Harbeth sounds just as good if not better than those speakers that are more inert than your kitchen countertops.

I think Harbeth may be perfect for me if my rig was connected to an improperly wired electrical system (phase reversed) with multiple many electrical devices on it, all having differing potentials for ground, various impedance mismatches between components and of course no absolute phase switch in sight. Yes,just right...
