Possibly Unsafe is back with a speaker upgrade! Turns out capacitor performance degrades over time… and as ESR (Equivalent Series Resistance) goes up, the highs go away. So this week we’re replacing the capacitors on a pair of vintage Klipsch speakers to restore the sound back to the original spec. It’s easy… and there’s a good chance upgrading the capacitors in your crossovers could make for better sound.
