BS EN 60268-5:2003+A1:2009

This standard BS EN 60268-5:2003+A1:2009 Sound system equipment is classified in these ICS categories:

• 33.160.50 Accessories

This standard applies to sound system loudspeakers, treated entirely as passive elements. Loudspeakers with built-in amplifiers are excluded.

NOTE 1 The term “loudspeaker” used in this standard relates to loudspeaker drive units themselves and also to loudspeaker systems, which comprise one or more loudspeaker drive units provided with a baffle, enclosure or horn and such relevant devices as built-in crossover filters, transformers and any other passive element.

The purpose of this standard is to give the characteristics to be specified and the relevant methods of measurement for loudspeakers using sinusoidal or specified noise or impulsive signals.

NOTE 2 The methods of measurement given in this standard have been chosen for their appropriateness to the characteristics.

NOTE 3 If equivalent results can be obtained using other methods of measurement, details of the methods used should be presented with the results.

NOTE 4 The following items are under consideration:

• loudspeakers with built-in amplifiers;

• measurements under conditions other than free-field, half-space free-field and diffuse field;

• measurements with signals other than sinusoidal or noise or impulsive signals.
