Saki, you are likely reading a review of the later model, which was 90db. The specs I gave are for the earlier model that I have, taken directly from the Owner's Manuel. The review in Stereophile was from around 2000-2001 by Robert Harley. Infinity no longer makes this speaker...they screwed it up with the later model.

P.S., I have seen them for sale for around $1,000, cost new was about $3,400. The only problem I ever heard about was that the speaker surrounds sometimes needs replacing. Mine are still good after 12 years, never any problem. Still play them nearly every day.

Polk Audio LSi25 is another option. Think they are out of production but not a bad speaker used.

Vandersteen 5, 5A, 7, Treo and Quattro fit that description.
