To add to Ralph's (Atmasphere's) comment, based on the specs shown at the end of this document the 93 db figure is based on 3 db of anticipated "room gain." The anechoic figure is 90 db, which IMO is probably what should be relied on when comparing the specs of this speaker to those of others. Also, the impedance curve shown near the end of that document indicates an impedance of about 5 ohms for most of the region below 1 kHz, where the majority of amplifier power is typically required. Sensitivity of 90 db/2.83 volts/1 meter corresponds to about 88 db/1 watt/1 meter for a 5 ohm load, which is definitely not high efficiency.
That said, the relatively flat impedance curve and the relatively small impedance phase angles at most frequencies suggest that this speaker should be fairly versatile in terms of amplifier selection. I wouldn't want to speculate, though, on how much of a difference you are likely to hear in your particular system going from the Outlaw to another amp you may consider. I would just say that the difference is likely to be less than it would be if your speakers had particularly challenging impedance characteristics.
In any event, kudos to Ascend for providing the detailed information they have provided in the paper I linked to.
Good luck. Regards,
