What the labels mean
- Maker's product page: copied from the maker's product page.
- Maker's datasheet: read off the maker's own datasheet or drawing.
- Worked out from the maker's figures: Vd = Sd × Xmax, EBP = Fs ÷ Qes.
- My earlier listing, not yet checked: from the listing I had before I started checking figures against makers. Treat it as a guide until it's checked.
- NB Audio's listing: how I've filed it in the store.
