I inherited a pair of speakers my dad bought in the early 80s. They still work well, though the amp died last year and I wasn't able to repair it.
Many will also support Bluetooth so you can stream to your stereo.
Just Google for 'SBC codec transparent' if curious.
Bluetooth's A2DP only real problem is the unspecified latency requirements.
Several companies make all-in-one bluetooth speakers that have amps built in, but they tend to be lower quality in my experience.
