Back in the 80s or 90s you would have needed 2 car batteries in row to get a bass heavy sound like the kids are blasting today on their little blutooth speakers. What gave the technological boost, better batteries or better speaker tech?

As others already stated, amplification is more efficient and power storage has improved heavily.
I would also like to add that the case/enclosure design has gone really far too!
The speakers are not just screwed into a wooden box – the enclosure is really well designed to amplify the soundwaves on just the right frequencies..
