0 dBV (1 V rms) continuous average is typically the onset of limiting for noise and music. Pink noise
has 12 dB peak-to-RMS ratio
Audio source must be capable of producing +16 dBV (6.3 V rms) into 600 Ω to produce the maxi-
mum peak SPL over the operating bandwidth of the loudspeaker with a sine wave.
