One speaker?
Stereo from one speaker would indeed be impressive, but the review says this unit has three drivers: one in the middle and one at each end. If that counts as "one speaker", then so does a more conventional single cabinet containing two speakers: one left and one right. Boom-boxes and some instrument amplifiers have been doing that for decades; you get a degree of stereo image. Now perhaps this unit's unconventional layout does give a better stereo image, but I'm highly dubious about claiming it does so with "one speaker".
