The whole idea of turning a tabletop into a speaker has always sounded weird to us, but apparently there's a market for it.
A few months back we saw the "Nimzy Vibro Max" (sounds like an adult toy from Jabberwocky), and now we get word of the "I-mu Magic Audio Frequency Singer." Both claim to play music or other sounds through any hard surface.
China-based Vavolo describes the I-mu as "a new revolution in the audiovisual field," according to Chip Chick. We don't know about that, but we do see that its $89 price is about half that of the competing Nimzy. Either way, we're going to pass. Call us old-fashioned, but we think the coffee table should be seen, not heard.
