[QUOTE="Jack Arnott, post: 148284, member: 304"] Re: Extension thread from " An Open List of Console Feature Requests" Thread In my mind, it goes beyond this. Just getting coverage to the whole audience from both hangs is not enough. The whole audience needs to be within an certain distance of both hangs. There are very, very, few instances where this happens. Is this the one titled "Debunking Stereo"? This was linked on the old LAB and was the piece that turned my mind around about stereo. One bit was about spacing of speakers. (I paraphrase liberally, when it would be better to be able to post the link, but I can't find it anymore, and wish I had saved it.)
