Simple Explanation

A speaker or system that tries to play all sounds—from deep bass to high treble—without needing extra speakers.

Concise Technical Definition

A device or driver designed to reproduce the entire audible frequency spectrum (typically 20 Hz to 20 kHz) without the need for a crossover or additional drivers.

Layman-Friendly Analogy

Like a one-man band trying to play every instrument at once—some do better than others.

Industry Usage Summary

“Full range” often refers to single-driver speakers or systems claiming coverage of the entire audio band, though true 20 Hz–20 kHz performance is rare, especially on the low end.

Engineering Shortcut

Covers full 20 Hz–20 kHz band, often with a single driver; no crossover.

Full Technical Explanation

The term “full range” refers to a speaker, driver, or audio device capable of handling the entire audible frequency spectrum, typically 20 Hz to 20 kHz. In practice, many so-called full-range systems do not reach the lowest frequencies, particularly below 40 Hz. Full-range drivers aim to eliminate the need for separate woofers and tweeters by using a single transducer. While they can offer coherent imaging and phase alignment, they often compromise on bass extension or high-frequency detail. True full-range systems—especially those maintaining flat response across the spectrum—are rare and often require trade-offs in size, efficiency, or complexity.
