Simple Explanation

Speakers built into the wall so they don’t take up space or clutter the room.

Concise Technical Definition

Flush-mounted speakers installed directly into wall cavities, using either the wall’s airspace or a dedicated back box as an enclosure.

Layman-Friendly Analogy

Like built-in bookshelves for sound—tucked into the wall and out of the way.

Industry Usage Summary

Common in home theaters and multiroom systems where aesthetics and space-saving are priorities; also referred to as architectural speakers.

Engineering Shortcut

Wall-mounted flush speaker; air cavity or back box = enclosure.

Full Technical Explanation

In-wall speakers are a type of architectural speaker designed to be installed flush within a wall, providing a clean and unobtrusive look. They use the wall cavity as part of the enclosure, though high-performance designs often include a back box to control acoustic performance and limit sound leakage. In-wall speakers are used in home theaters (for front, surround, or even center channels), whole-home audio systems, and commercial spaces where aesthetics, space, or concealment is a priority. Proper placement, wall construction, and insulation are critical for achieving optimal sound quality and minimizing unwanted resonances.
