Biamping was very effective when audio amps ran several percent IM distortion, and 20 watts was a powerful amp. Limiting the bandwidth of the signal going through the amp helped. Also, as a secondary benefit, greater power could be achieved.
With modern amps these factors no longer exist. Biamping between a subwoofer and the main speakers is the exception, because of the cost of quality inductors of the values needed for SW crossover frequency. And SW power considerations.
Biamping, or multiamping still makes sense for pro audio applications, but that's a different story.
