Hello,

apparently there are certain low frequency bass sounds that make people feel
squeezy or irritated. Anyone know, where I might find those on the net?

Make your own. Use an audio editor to halve the playback speed of your
favourite bassy tracks, or just to generate sine waves at 15 to 30Hz.

The problem is finding a speaker that will generate decent levels at low
frequencies
although I found that while tuning a bass-reflex cabinet, less than 1v
at 20Hz
across a 4ohm driver was nauseating.

You could use a Harley with drag pipes at tickover.
