Rockport Technologies addresses cabinet vibration?


Genius? Really puts the competition in their places,imho.

Magico has done this with all there speakers plus they sound great as well.
If memory serves Rockport utilizes shipbuilding techniques in the construction of their speakers, always has. 
Wilson also has some very inert cabinets. Then there are Audio Note speakers whose cabinets are designed to vibrate like a violin.
