Late in the day at the Show, most glasses were filled or in the process of being emptied. This stack on the BG stand, however, was empty. It had been erected to show that Radia's new 210i Active Subwoofer is almost totally vibration-free in operation. At the time I took this picture, this sub, with its opposed 10" Kevlar drivers and 500w BASH amp was pumping out gobs of bass, cleanly and tightly. I could detect no vibrations at all with my hand. What's the point? Well, you can put something on top of them (vase, planter, cigar humidor!) without exciting spurious vibrations. Heck, you could even put this $1500 sub in a cabinet, if that suits your needs.
