Simple Explanation

A setup using one subwoofer or low-frequency source to reproduce bass sounds in a space.

Concise Technical Definition

A single bass array (SBA) is a configuration where one subwoofer or a single line of subwoofers is placed along a wall—usually the front wall of a room—to generate low-frequency energy. It is often used in room modes and wavefront control applications, with basic time-alignment to reduce bass reflections from room boundaries.

Layman-Friendly Analogy

Like having just one big bass drum in a room—it shakes the room, but the sound might bounce around unevenly depending on where you're sitting.

Industry Usage Summary

Used in home theaters and some professional listening rooms, a Single Bass Array is a simple solution for bass reproduction but is often prone to uneven bass distribution due to room modes and boundary reflections. More advanced setups (like Double or Triple Bass Arrays) are preferred in acoustically critical environments.

Engineering Shortcut

SBA = one subwoofer (or aligned line) = simple setup but uneven bass response.

Full Technical Explanation

A Single Bass Array typically refers to the use of one subwoofer or a single row of subwoofers located at the front of a room. While effective for generating low-frequency sound, this configuration often leads to issues with room modes—causing boomy or weak bass in different areas. Unlike multi-sub configurations, SBAs don’t cancel rear wall reflections, resulting in modal peaks and nulls.
