Simple Explanation

A loudspeaker with an integrated amplifier, so it doesn’t need an external power source to function.

Concise Technical Definition

A powered loudspeaker is a speaker with a built-in amplifier, eliminating the need for an external amplifier. The amplifier drives a passive crossover, which then directs the appropriate signal to each of the speaker's drive units (e.g., woofers, tweeters).

Layman-Friendly Analogy

Think of it like a self-contained sound system. A powered speaker has everything inside it—just like a lamp with a built-in light bulb—so you don’t need to plug in separate components.

Industry Usage Summary

Powered loudspeakers are widely used in both professional audio systems and home audio setups, providing convenience and reduced complexity. These speakers include an internal amplifier, eliminating the need for an external amp and simplifying the setup process. Powered monitors, often used in studio settings, provide high-quality, accurate sound reproduction and are commonly used for mixing, monitoring, or performance.

Engineering Shortcut

A loudspeaker with an integrated amplifier that drives the speaker’s crossover and drive units.

Full Technical Explanation

A powered loudspeaker, also called an active speaker, includes an integrated power amplifier inside the cabinet. This eliminates the need for an external amplifier, simplifying the audio setup. The internal amplifier drives a passive crossover network, which separates the audio signal into different frequency bands and sends each band to the appropriate driver (woofer, midrange, or tweeter). Powered loudspeakers are especially convenient for live sound and portable applications, as they require fewer components and cables. They are also commonly used in professional audio setups, where ease of setup and precise control over amplification are important.
