About the iQ90
The KEF iQ90 is a three-way floorstanding loudspeaker from KEF’s iQ series, designed around the company’s Uni-Q coaxial midrange/tweeter array for wide dispersion and precise imaging. It uses twin 165 mm bass drivers with a 165 mm Uni-Q mid/tweeter section, housed in a curved bass-reflex cabinet intended to improve rigidity and reduce internal reflections. The iQ90 was aimed at both stereo and home theater use, offering high sensitivity, strong output capability, and a refined, spacious presentation. This model is no longer current and is generally found only on the used market.
