Overview

EN 61305-5:2003 (IEC 61305-5:2003) defines standardized methods of measuring and specifying the performance of loudspeakers used in household high‑fidelity audio equipment. Published by CENELEC/IEC, it is part of the IEC 61305 series covering measurement methods for consumer hi‑fi components. The standard applies specifically to sound‑system loudspeakers for household high‑fidelity use and references IEC 60268‑5 and IEC 61305‑1 for measurement and environmental conditions.

Key topics and requirements

• Scope and references
  • Measurement electrical conditions: as specified in IEC 60268‑5.
  • Climatic and general measurement assumptions: as specified in IEC 61305‑1.
• Essential measured characteristics (from Table 1)
  • Frequency response (free‑field) - sound pressure level vs. frequency (per IEC 60268‑5).
  • Effective frequency range - range over which response does not vary by more than 10 dB.
  • Acoustic power frequency response - sound power in 1/3‑octave bands.
  • Difference of frequency responses for matched pair operation.
  • Characteristic sensitivity level measured over the effective frequency range.
  • Maximum sound pressure level limited by distortion - SPL at the point where total harmonic distortion (dt) or intermodulation distortions (d2, d3) reach 10%; distortion measurement referenced to IEC 60268‑5. The test frequencies use f1 = lower limit of the effective frequency range and f2 = 8.5·f1.
  • Rated impedance - value of a pure resistance substituting the loudspeaker.
  • Rated noise power and rated sinusoidal power - calculated from rated voltages and rated impedance.
• Specification and labeling requirements
  • Documentation for users must include at least items 1, 2, and 4–9 from Table 1.
  • The loudspeaker label must include at least items 2, 7, 8 and 9 (effective frequency range, rated impedance, rated noise power, rated sinusoidal power).

Applications and who uses it

• Loudspeaker manufacturers use EN 61305‑5:2003 to produce comparable, traceable performance data for product datasheets and labels.
• Test laboratories and QA teams implement the specified test signals, environmental conditions, and measurement procedures to validate product performance.
• Product designers and audio engineers rely on standardized metrics (sensitivity, SPL limits, frequency range, impedance) for system integration and loudspeaker selection.
• Retailers and reviewers refer to consistent specifications when comparing consumer hi‑fi loudspeakers.

Related standards

• IEC 61305‑1 / EN 61305‑1 - Household hi‑fi equipment - Part 1: General (general measurement assumptions and climatic conditions).
