Sarcastic, yet ignorant. Rear-facing tweeters is an old idea. The idea is they use wall reflections to improve stereo imaging. The benefit isn't clear, and it adds to the price, since you need double the tweeters. But many very well received, high quality loudspeakers have used the concept (and Bose uses it too!) There are nuances (bipole vs. dipole, delay, eq, etc.), and the subject is quite complex.
@WhyFi,
I agree. It cracks me up when people (not just Engadget writers) talk about 4" or even 6" "subwoofers." A subwoofer produces output below 80 Hz (and really, below 60 Hz.) That requires at least 8" drivers, plus hundreds of watts of amp power. The 4" drivers in the Expressionist units are just "woofers," or even "midranges." Even those boxes that sit on the floor in 2.1 multimedia systems aren't "subwoofers".
The phone has 256MB of RAM and a 1GHz processor, which do the job reasonably well, though the Anna interface will likely leave something to be desired for many smartphone users.
