There have been quite a few comments on the web regarding the New York Times article on Bang & Olufsen’s new loudspeaker product (for example, here, here, here, and here among others). In addition to the Dave Moulton designed tweeters, the auto-magic room-equalization function seemed to elicit a lot of comments.
