This part applies to loudspeakers and loudspeaker systems which are provided with a baffle or enclosure. It also applies to systems intended to be assembled by the user (so-called “loud-speaker kits??) provided that the instructions for assembly meet certain requirements (see Clause 16). The minimum requirements of this part then apply to the complete device, together with the baffle or enclosure. This part is not applicable to loudspeakers and loudspeaker systems comprising active components. For the combination of loudspeakers and amplifiers reference is made to IEC Publication 581-8: High Fidelity Audio Equipment and Systems; Minimum Performance Requirements, Part 8: Combination Equipment. This standard is not applicable to unmounted loudspeaker units.
