You'd be surprised how shitty most "modern" speakers are.
Size is still king. Doesn't matter how fast your fancy microcontrollers are. The big-ass cabinets from the 80s and 90s still sound incredible when you put them next to the typical experience you'd find on the shelves of Target or Best Buy.
Often the woofer on the speaker is larger than a modern 5.1 subwoofer.
However, it is frustrating that I can't get modern speakers anything like my parents' three-ways with a 12 or 15 inch woofer without finding some esoteric offering.
You can get "modern" builds of the very same loudspeakers right now with major brands like Klipsch - https://www.klipsch.com/heritage-premium-audio The AK6 is still considered by many to be the best loudspeaker you can ever own.
Mainly because the market did large speakers is so much smaller now. Feels like the price/quality trade off is about the same as it was 40 years ago.
The speakers that are “a fraction of the price” now are there, but they’re really terrible Chinese-made junk for the most part.
Do you think people are getting new suits because they are "worn out", or perhaps because they're no longer in style?

I'll bet modern engineered speakers will beat those high quality speakers, at a fraction of the price. That's modernity.
