## Abstract

The Federal Trade Commission ("Commission" or "FTC"), pursuant to section 18 of the Federal Trade Commission Act, issues final amendments to its Trade Regulation Rule on Power Output Claims for Amplifiers Utilized in Home Entertainment Products ("Amplifier Rule" or "Rule"). The Commission amends the Rule to: exempt sellers who make power output claims in media advertising from the requirement to disclose total rated harmonic distortion and the associated power bandwidth and impedance ratings; clarify the manner in which the Rule's testing procedures apply to self-powered subwoofer-satellite combination speaker systems; and reduce the preconditioning power output requirement from one-third of rated power to one-eighth of rated power. This document constitutes the Commission's Statement of Basis and Purpose for the amendments.
