(This came up in another thread but I'm posting it here to keep that one more on topic.)
There is a very straightforward answer to the thread title in the wider audio world that I'll see if I can try to convince any doubters the value of
. I do totally get why some use alternative language though and there was a time when I would have as well!
The perspective to have in mind is that of the listener, sitting in their hopefully comfy chair facing their speakers. The front wall is then the wall in front of them and the rear wall the one behind them. Similarly the left speaker is the one to the listener's left and the right to their right. Anyone who has ever connected up speakers to an AV amp will note this is precisely how everything is labelled and it is only in the stereo world where there might ever be confusion.
The alternative is to choose to view things from the perspective of the speakers, with their drivers facing 'forward' and the wall behind them then being referred to as the 'back wall'. Where this most obviously then falls down is if you consider left and right. If I view things from the speaker perspective then 'my' left will be the opposite to the listener's left and vice-versa. If you watch a movie then there is very clearly a left audio channel which is associated with what is to the left of the image from the viewer's perspective. Similarly in music there is always a left audio channel which is intended to be to the left from the listener's perspective. For lots of music this doesn't actually make any difference but most obviously for live classical recordings there is a well established layout for where different instruments usually are that relates to what the true left and right channels are. If someone defines layout from the speaker perspective then they end up having to send the left audio channel to their 'right' speaker, almost certainly using an amplifier output labelled 'left'. And vice versa.
Common language is of course helpful to avoid confusion, which is why I do sometimes make the point that the listener-centric terminology really is the 'correct' one. Rather than being purely pedantic, honest
