CTA’s Canvass Committee has recently published ANSI/CTA-6000, Sound System Equipment - Part 5: Loudspeakers IEC 60268-5 –Ed. 3. This standard represents the US National Adoption of IEC 60268-5 –Ed. 3., which applies to sound system loudspeakers, treated entirely as passive elements. Loudspeakers with built-in amplifiers are excluded. It gives the characteristics to be specified and the relevant methods of measurement for loudspeakers using sinusoidal or specified noise or impulsive signals. This third edition cancels and replaces the second edition published in 1989, amendment 1 (1993) and amendment 2 (1996). It constitutes a technical revision. For more information and to access the standard, visit Sound system equipment - Part 5: Loudspeakers.
