In order to measure maximum linear sound levels meaningfully and repeatably, a signal is required whose RMS and peak levels as functions of frequency have been shown to be representative of program material. ![]() "Abstract: This standard details a procedure for measuring maximum linear sound levels of a loudspeaker system or driver using a test signal called Music-Noise. Looking at KEF's published specifications for the Blade Two Meta for comparison, KEF lists max SPL at 116_dB, but with no SPL filter weighting or other conditions mentioned.Īudio Engineering Society has recently published AES75-2023, The 200W maximum power handling is presumably a thermal limit rather than a nonlinear distortion based limit or mechanical excursion based limit, and that thermal limit is presumably relative to a longish time averaged interval of music signal rather than accomodating signal crests without significant mechanical clipping. The specs in this review and in TAD's marketing webpage do not include maximum SPL, which is useful in determining the maximum signal crests which can be accomodated relative to a specific propagation distance and Lref (reference level).
