20 years is an eternity for consumer electronics. The interconnects and power delivery of my devices weren't even invented yet in 2003.

That said, a good 2003 loudspeaker is still a good 2023 loudspeaker. I'm in favor of granting amnesty to legacy sunk costs as long as it still serves the needs of today.

You can open up the loudspeaker and checking the crossover circuitry for any capacitor leaks or swelling. I don't think it'll be an issue for another decade or two.
