If I wanted to get a nice pc speaker and wire it up to a connector for the motherboard, what would the ideal specs be?

  • wattage
  • ohms

I know it is vary low power, but I am wondering if there is a spec.

Typical speakers I see are 8ohm and 0.1...0.5W but in general there's no strict spec requirements. Neither power or impedance specs matter much, there's not enough current to try a speaker and the 5V driver voltage will make even high impedance drivers sound loud enough.

The typical PC speaker is a 3" cone speaker, like you'd find in an old AM transistor radio. So 8 ohms, as little as .1W power handling, harsh sounding and not really capable of reproducing music.

A better speaker with a rolled surround won't make square waves less primitive, but it will make PWM and PCM audio not only intelligible but pretty unreasonably good for the PC speaker system. Can achieve sound not much worse than a noisy, cheap Covox clone, or good enough for Windows 3.1 sound effects.
