This page does not review anything Bowers & Wilkins makes. It counts one thing: how much of what this database says about their products came out of their own documents, and how much had to be worked out or left blank.

Where each sensitivity figure came from

ModelImpedanceSensitivitySource of the figure
P722 Ω94.4 dB/mWConverted from per volt

Impedance is almost always printed. Sensitivity is the one that goes wrong, because a decibel figure means two very different things depending on whether it is per milliwatt or per volt — about five decibels apart at 300 Ω and eighteen at 16 Ω. The conversion is here.

  • Converted from per volt — 1: the maker prints a figure per volt, converted here with dB/mW = dB/V − 10·log10(1000/Z)
