Throwing a figure like 20,000% around seems absurd. Rarely is
anything we use in our normal lives 20,000%
more/less/better/worse/whatever than a competing product. Yet,
AudioMasons claim their stone speakers are 20,000% greener than other speakers. Seriously?
In addition to desirable resonance qualities, the stone used to make
their speakers is apparently highly sustainable. The $1146, 2-way Comet speaker features 7-inch and 1-inch drivers, with a frequency response of 42Hz - 20kHz. 
But Treehugger's Lloyd Alter isn't so sold on that idea. First, he
points out that their touting of LEED qualification is strage: that's
generally for buildings and structures as opposed to consumer products.
Secondly, the 20,000% figure
comes primarilyfrom comparing the stone encasements of their speakers
to a speaker whose enclosure is cast from virgin aluminum (though they
also calculate the energy saved as well). And sure, there are
aluminum-encased
speakers, but I wouldn't call them the de facto
standard of audio gear. And lastly, Alter points out that the process of
cutting and shaping stone isn't all that green. The claim to
eco-supremacy appears to be hype more than anything else. [AudioMasons via TreeHugger] |
