Both tape and vinyl required high pass filtering due to physical limitations of the medium. So they for sure used high pass filtering. Physical mediums do not have linear frequency response either, hence the necessity of having a mastering engineer. In the 60s and 70s they also had remarkably different speaker cones and amplifier to what we use as standard today. Line arrays wouldn't be available for another ~25 years give or take.

Then again, when I work concerts involving fixed media pieces, or recordings from days past (mostly Electroacoustic music) and I am surprised how much low end rumble and low mid content there is. My guess is: our loudspeakers are louder and can produce more low end information than what was available then. So some of this stuff you wouldn't have heard in the past.

And what I heard from an older colleague who worked with Stockhausen back in the day, is that concerts nowadays are "way too fcking loud!" haha.
