CEA-2031 defines test procedures for rating the performance and physical size of mobile loudspeakers, and requirements for reporting these characteristics. CEA-2031, when used in conjunction with CEA-2006-A, Testing & Measurement Methods for Mobile Audio Amplifiers, enables consumers to select mobile loudspeakers with power handling capabilities that are appropriate for the power output characteristics of their mobile amplifiers.
Mobile Loudspeaker Mark: This mark indicates that a car loudspeaker has been tested to CEA-2031. The mark requires that manufacturers report primary power output in watts, cut-out diameter, mounting dept, impedance and maximum rms power output in watts, total harmonic distortion (THD) plus noise and signal to noise ratio.
