This page does not review anything Campfire Audio 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

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
  • Not published — 5: no sensitivity figure in anything the maker published

What the paperwork adds up to

Rather less than half of what this site says about Campfire Audio came from them. The rest is arithmetic, and it is marked as arithmetic on every page.

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.
