How to read speaker sensitivity rating?

.
When reading the sensitivity rating on speaker specs, does a lower number mean the speaker is easier to drive than a speaker with a higher number? Such as a speaker rated 78 db would be easier to drive than a speaker rated 102 db?

Plus, how many companies recommend a minimum of 60 wpc amp? That should tell you something.

Looks like they still have some parts too.[http://www.harmanaudio.com/search_browse/partlist.asp?Parts=CS969000&BrandId=INF&MarketId=HOM&Language=ENG&Country=US&Region=USA]

I don't believe this is the original manual. It shows the product history, which wouldn't make any sense for a new product. Also, the revised 6-98 date printed on it. Must of been definite errors made somewhere. The new parts still available doesn't match up correctly, whatever one may be right or wrong.[http://www.infinity-classics.de/infinity/technik/manuals/Kappa_9_technical_sheet.pdf]

Hifihvn...you are right on both counts. The Harmon site has the model number correct, but the parts are for the Kappa 9.1, not the original Kappa 9. The Kappa 9 does not have an 8 inch mid-bass driver...it has a Polygraph and a Polydome drivers that do not appear on the parts sheet on the Harmon site. The Kappa 9.1 was a ported design that was much easier to drive than the original Kappa 9. The bass drivers were different also.
