This page does not review anything Elysian Acoustic Labs 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
Annihilator22 Ω99.4 dB/mWConverted from a stated voltage
Annihilator 202622 Ω99.4 dB/mWConverted from a stated voltage
Apostle 202610 Ω97.0 dB/mWConverted from a stated voltage
Pilgrim9 Ω100.5 dB/mWConverted from a stated voltage
Pilgrim Noir8.3 Ω102.2 dB/mWConverted from a stated voltage

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 a stated voltage — 5: the maker prints a level at a stated drive voltage, converted here to per milliwatt

What the paperwork adds up to

Almost everything this site says about Elysian Acoustic Labs came from them. That is not the normal case and it is worth saying out loud.

The rule used here is the same for every maker and is described on the manufacturer index. Every figure behind it can be opened on the product page it came from, with the document it came from linked.
