i looked up some of the infinities. some were as low as 90db for 1watt/1meter were the klispch are 100db or so. what that means is, at 128 watts, the infinity is putting out 110db, the klipsch needs 8 watts to put out 110db.
still, a very nice sounding speaker and an even better deal. some people have all the luck.

Loudspeaker "efficiency" is kind of an irrelevant metric to gauge sound
quality on though (IMO). Most higher-end stuff comes in well under 100db 1w/1m (I've heard some phenomenal systems with 1w/1m barely over 80db). System/brand/model (ohm) loads vary greatly (2Ω - 16Ω) making it that much more of a useless statistic (but good for marketing). In quality systems, the drivers are usually better damped, both physically (surrounds/spiders) and mechanically (VC's/motors). The filter networks are typically more elaborate than a single cap/coil as well. The end result is usually a more balanced, neutral sound, at the expense of efficiency (quality vs. quantity). That said, not all "inefficient" loudspeakers are quality by default! YMMV.
