Wolf , tagging you since this is the Missing Link woofer and you may know pretty quickly.
I want to trace the graph of the Dynavox LW6004HR-N woofer. The top portion of the manufacturer's spec sheet shows sensitivity at 87.92 db @ 2.83V/1m, which is consistent with what WinISD calculates based on mfg's TS parameters.
BUT...the mfg's frd curve "looks" lower to me. Since the frd curve is not a flat line maybe this curve really is a 87.92 SPL as listed in the top portion. But, right under the impedance graph in the LinearX "Notes" it says SPL = 85.9 db, which is consistent with 1w/1m. (It is a 6 ohm nominal woofer.) If the frd curve is at 1w/1m, I can just adjust for it when tracing, but I don't want to adjust by 2 db if the mfg's frd curve really is at 2.83v/1m. So, which sensitivity rating do you think is accurate for the frd curve shown?
