I remember a contemporary technology, Aureal's A3D, experiencing the magic of having one of their sound-cards and playing Counter Strike 1.x. Enemy footsteps felt almost as good as seeing them. Maybe it's nostalgia, but I never quite recaptured that sense with other hardware/games.

Another search-able term to drop in here is "Head-Related Transfer Functions" (HRTF), where the inputs are a sound and a given relative location, and the problem is how to subtly adjust that sound for each "ear", giving your brain the kinds of cues normally imparted by the shape of your ears and the different materials in your skull, etc.

Aureal suffered from a set of legal battles with a then-not-so-huge company named Creative, which eventually bought out the bankrupt remains.

I'm pretty sure Aureal A3D was featured on my family's Compaq Presario 5150[0] back in 1998. The speakers were decently sized units mounted on the side of the 17" CRT and powered straight from the soundcard via 3.5mm plug which apparently was designed to output way more power than a standard headphone jack because it could go pretty loud.

A couple nifty demos were included. One was simply a bee buzzing in a circle, and it totally sounded like it was doing loops behind your head.

    Old PC sound cards commonly had op-amps on their outputs that could produce a reasonably-clean Watt or two into a pair of 8-Ohm speakers.

    Which doesn't sound like much, but 100 Watts is only 20dB louder than that if all else is the same, and most casual music listening happens with peaks that are in the realm of tiny fractions of a Watt.
