Friendly reminder: while the behavior of the acoustic combination of signals is somewhat different than the combining of electrical signals, mostly due to the effect of an acoustic environment and speaker placement, even if one manages to keep all bass individually isolated in several channels and reproduce them independently, loss and/or boost, similar to electrical combination of signals, will occur in the listening environment as the sound waves interact.

Some would say that environmental acoustic interaction is better than electrical, somehow more as ‘intended.’ I suppose that would depend on how the method of recording and/or mixing were done as a means of producing something ‘intended.’ Unless it were for a specific purpose, engineers generally seek to keep signals in phase on various tracks. If there is some small drift in phase, the lower the frequency, the less impact a slight phase shift has. The electrical combination of bass signals is not automatically a bad thing, especially if it allows access to the reproduction of low frequencies in a room via one or more subwoofers that would have otherwise been left unheard.

If one were listening via headphones, there would be minimal combination of signals prior to interaction/interpretation in the brain, and for a ‘live’ stereo/binaural recording, this might be close to ‘intended’ in the ears, even if it leaves out the feeling of tactile bass.

Personally, I like aural and tactile bass together.
