Product Overview

Made in France in the Focal workshops, the 1000 IWSUB Utopia boasts brand new, exclusive architecture and can be installed horizontally or vertically. It incorporates the best Focal technology from the iconic Utopia line. Its three 6 1/2” (16.5cm) subwoofers with their W’ cones offer unrivalled power handling: the bass reproduction is sensational, in Stereo as well as Home Cinema listening sessions.

Constantly pushing boundaries, the engineers have designed and conceived this subwoofer so that it assembles perfectly with the 1000 IWLRC Utopia reference loudspeaker, but also with as many other 1000 IWSUB Utopia models as desired. Each product is connected to the others using the professional Speakon cabling provided: the only limit to the assembly options is your imagination!

Offering the ability to choose the impedance for each speaker driver according to the number of linked products, 1000 IWSUB Utopia allows an unrivalled audio installation without modifying your room, thanks to its ready-to-paint magnetic grille.

The discreet pleasure of powerful sound excellence...
