CTA's Audio and Video Systems Committee develops standards, recommended practices, and related documentation for consumer systems whose primary function is presentation of audio or video and associated content. All are encouraged to join the Audio and Video Systems Committee and get involved in its activities. The Audio and Video Systems Committee is particularly interested in adding new members (called "users") who acquire audio and video products from those who create them.

This document will include improvements to CTA-861-I.
This standard defines a method for measuring the audio performance of subwoofers, both passive and powered. The standard is being revised in order to incorporate new rating methods and to make additional edits as needed.
This standard describes how to determine the frequency response, directivity, and maximum output capability of a residential loudspeaker. It is intended to determine the audio performance of a loudspeaker, not the loudspeaker’s ability to survive a given input signal. The standard is being revised to incorporate new rating methods and to make additional edits as needed.
This standard will outline the performance attributes of a power amplifier in order to allow consumers / end-users to easily determine if a given amplifier is compatible with a given loudspeaker system.
This standard describes how to determine the maximum output capability of loudspeakers, subwoofers, and amplifiers intended for use in consumer/residential applications. It also describes how to determine appropriate crossover frequency region for and between loudspeakers and subwoofers.
