Simple Explanation

A subwoofer with a built-in amplifier, designed to produce deep bass without needing an external amplifier.

Concise Technical Definition

A powered subwoofer is a subwoofer that includes an integrated amplifier, which powers the subwoofer's driver. The built-in amplifier removes the need for an external amplifier, making it a convenient and efficient solution for reproducing low-frequency sounds in home theaters or audio systems.

Layman-Friendly Analogy

Like a mini sound system with everything inside the box: the subwoofer and the amplifier are built together, so all you need to do is plug it in, and it takes care of the rest.

Industry Usage Summary

Powered subwoofers are commonly used in home theater systems, professional audio setups, and live sound reinforcement. By integrating the amplifier within the subwoofer, they simplify the audio setup and reduce the need for additional external equipment. These subwoofers are designed to provide powerful, low-frequency sound to enhance music, movies, and other media experiences. Powered subwoofers are popular in both consumer and professional environments due to their convenience and efficiency.

Engineering Shortcut

A subwoofer with an integrated amplifier that drives the subwoofer's low-frequency driver.

Full Technical Explanation

A powered subwoofer is a subwoofer that comes with a built-in amplifier, designed to handle and amplify the low-frequency signals required to drive the subwoofer's driver. The integrated amplifier in a powered subwoofer eliminates the need for an external amplifier, making setup easier and reducing the overall complexity of the system. Powered subwoofers are typically designed to produce deep, powerful bass sounds, often used to enhance home theater systems, music production, and live sound applications. These subwoofers can feature various amplification designs, including class D, class AB, or other efficient amplifier types, depending on the application and desired performance.
