CEA Adopts Standards For Powered-Sub Output

The Consumer Electronics Association hopes to make it easier for consumers to compare powered subwoofers with the adoption by its audio systems committee of standardized test procedures for measuring powered subs’ sound-pressure-level (SPL) output.

The standard, dubbed CEA-2010, specifically test procedures for determining maximum SPL output and defines a ground-plane test procedure and room-correction factor. The standard, which took two years to create, outlines reporting requirements for compliance with the standard.

“Broad implementation of this standard will provide consumers who are interested in quality subwoofers the ability to make an informed purchasing decision,” said Charlie Hughes, chairman of the working group that developed the standards.
