[QUOTE="squeak9798, post: 2014614, member: 555320"] Upon re-reading, if you were using "Fs/Qts" as the calculation for sensitivity (rather than meaning you used both Fs and Qts [which is not correct for either formula] in the calculation for sensitivity), then therein would lie the problem. The formula Fs/Q[I]e[/I]s is used to calculate EBP (efficiency bandwidth product), but that is [B]NOT[/B] the same as the sensitivity of the driver. EBP is essentially a ratio between the Fs and Qes to quickly determine which enclosure type (sealed or ported) the subwoofer would be most suitable for. Completely different than senstivity. If what I wrote above is correct, then apparently the term "efficiency" in the name of the measurement is what confused you. [/QUOTE]
