This circuit uses a tda1521 as a two-channel power amplifier, and another tda1521 btl output is used as subwoofer amplifier. ic1 and ic2 may use the ne5532, jrc4558 or tl082. You can also use other high-end op amp such as op275, lt1057, opa2604, etc. But for computer speaker, the ordinary op put is enough.
