I think the 6.2 Stereo Everywhere was fairly short-lived but I don't really follow Bose. IIRC it's a two-way design with a ported 8" woofer and a pair of 3" mid/tweeter drivers angle-mounted in front of the woofer so they radiate off to the left and right to provide that (in)famous Bose dispersion. There are no rear speakers. More @Wikipedia
