The Res Extensa EP is a two-track 10-inch by Felix K, released on Hidden Hawaii (cat. Hidden Hawaii Ltd. 007) as a companion to the Res Cogitans EP. It contains "Res Extensa" and "Aussenwelt," both later collected on Archive #1. Hard Wax described it as "killer leftfield drum & bass / ambient hybrids." The title (Latin for "extended thing") completes the Cartesian pair begun by Res Cogitans.
