Simple Explanation

Using two amplifier channels to power different parts of a speaker, such as the woofer and tweeter.

Concise Technical Definition

A speaker setup method where separate amplifiers are used to drive the low- and high-frequency drivers (e.g., woofer and tweeter) independently, bypassing the shared passive crossover.

Layman-Friendly Analogy

Like having two people pushing a swing from opposite sides—one controls the bottom (woofer), the other the top (tweeter)—so they don’t get in each other’s way.

Industry Usage Summary

Common in high-end or professional audio setups where separate amps are used for bass and treble to improve headroom and control. However, audible benefits are often debated unless paired with active crossovers.

Engineering Shortcut

Bi-Amping = 2 amps for 1 speaker’s high and low sections.

Full Technical Explanation

Biamplification (or Bi-Amping) involves splitting the audio signal before amplification and using two separate amplifier channels to power different drivers in a loudspeaker—typically the woofer and tweeter—each receiving only the frequency range it’s designed for. This can reduce intermodulation distortion and improve control, but benefits depend on proper system design, active crossovers, and speaker compatibility.
