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