Close, but no cigar. "Efficiency" is a measure of just that... what percentage of an electric watt IN is converted into (fractional) acoustic watts OUT. You won't see "efficiency" specified much; most speakers are a few per cent efficient.Sensitivity is defined dB per watt (or, generally, at 2.83VAC, which is indeed 1W at 8 ohm but 2W at 4 ohm) at some fixed distance (typically 1 meter, but at 40 feet for the old EIA spec).
Your speakers are worth a try on a 300B SE amp (ca. 8W,usually), IMNSHO.
all the best,
