L+R, L-R encoding has been in use for a while. It allows the mono and stereo components of a signal to be compressed into limited bandwidth differently. FM stereo radio uses it. Some surround sound formats are based on manipulating the dynamic range of a L-R signal then playing it behind the listener. The old "Stereo Wide" trick removed midrange audio from the L+R component to make boom boxes sound bigger.
And why is a Bose a standard unit for comparison? Peaks in the mid-treble and mid-bass are used to mask an overall poor frequency response. It makes a decent first impression but it grows tiring, even headache inducing, after about half an hour. There's actually science behind the old saying, "No highs? No lows? Must be Bose." Want to see pictures of the premium Bose speakers in my car? They're cheap junk; worse than what you'd get from factory speakers.
