Making hi-fi speakers with drivers fashioned from woven hemp fibers might sound a bit like the plot for a long lost Cheech & Chong movie. The people behind Omega Speaker Systems however, will insist that the HempCone drivers they use have improved acoustic properties compared with more traditional paper or plastic. While I'm sure they could wax poetic for hours about hemp's natural damping, strength, and ecological sustainability, my hunch is that they just like to pop on a Bob Marley album, then talk about how the speaker cones come from the same plant as that giant doobie Bob was smoking in the studio. The cones are even a cool shade of green to remind you of their origin.
