Simple Explanation

The part of the bass you hear as punchy and rhythmic—not super deep, but very present.

Concise Technical Definition

A frequency range within the broader bass spectrum, typically centered between 100 Hz–200 Hz or sometimes extended to around 400 Hz, depending on context.

Layman-Friendly Analogy

Like the chesty thump of a kick drum or bass guitar—it’s not sub-bass rumble, but it still hits hard.

Industry Usage Summary

Mid-bass is critical for delivering punch and body to music and film soundtracks. It's shaped by woofer performance, enclosure design, and crossover tuning, and varies slightly in definition depending on system design.

Engineering Shortcut

100 Hz–200 Hz (sometimes up to 400 Hz); punchy bass region.

Full Technical Explanation

Mid-bass refers to a subrange of the bass frequency spectrum, commonly defined as 100 Hz–200 Hz, though some systems extend it to 200 Hz–400 Hz depending on how they divide the full bass range (typically 20 Hz–300 Hz). This region is where much of the punch and impact of percussion and rhythm instruments is perceived—especially kick drums, bass guitars, and synth bass. It adds warmth and body to sound without reaching the low-end rumble of sub-bass. In speaker and room design, proper handling of mid-bass is crucial for avoiding muddiness or boominess, which can obscure clarity and detail in both music and dialogue. Crossovers, room treatment, and speaker placement all affect the perception and control of this range.
