When I was working in a shop that sold both models, I actually preferred the balance of the 802. The 801 will better it, though, for sheer bass weight and slam (but will require a brawnier amp). All in all, taking the size, weight, appearance, and price into consideration, I would have taken the 802's (especially for average-size rooms) even if they sounded the same except for the bass. However, I found the 802 to be generally smoother and more listenable. Given that the mid/tweeter modules are the same between the two models, I would have to assume the difference lies either in the way the 801's 15" woofer must be crossed-over to the mid, and/or the demands it places on the partnering amplifier - either way, what the big woofer can gain you in the low bass seems to be prone to extracting a similar price through the mids. But I should add that my exposure to various set-ups with both speakers is somewhat limited (amplification on both tended to be big Levinson and ARC SS, cables Transparent or Monster, speakers were set up in the same large room), so my impressions must likewise be qualified.
