Genelec F One active subwoofer has an extremely small size yet an astonishingly bold performance, and it is able to reproduce low frequencies down to 35 Hz. The subwoofer makes a perfect pair for the active speakers of the Genelec G range. Thanks to its many inputs and range of remote control options, you can use the subwoofer as a hub to control your home audio system. F One can also learn IR remote control commands. The integrated bass control directs all frequencies under 85 Hz to the subwoofer, enabling the main speakers to focus on the rest of the spectrum. 

The Genelec speakers have been designed to provide the listeners with even the most subtle nuances without removing or adding anything to the original sound. The rounded lines and refined design by Harri Koskinen gives the Genelec speakers a lovely, Scandinavian vibe. The Genelec speakers are manufactured in Iisalmi, Finland.

Harri Koskinen

Harri Koskinen (b. 1970) is a versatile Finnish designer who has studied at the Lahti Institute of Design and at the University of Art and Design in Helsinki. His international breakthrough was in 1996 with the Block lamp, which is already considered a Scandinavian design classic and has been part of the MoMA’s permanent collection since 2000.

Koskinen’s creations include a wide range of different products – furniture, tableware, glassware, lighting, watches, textiles and much more – designed for world-renowned brands. Some of his best-known products are the candleholder Lantern and the All Steel pot series designed for Iittala, the K chair for Woodnotes, and a series of active speakers for Genelec.

At the Milan International Furniture Fair 2009, Koskinen presented his own brand Harri Koskinen Works, under which he produces his own furniture range. Koskinen’s design is characterized by functionality and strict aesthetic criteria – he is always looking for innovative solutions for both the consumer and the producer. Since 2012, Koskinen has been the Design Director of Iittala.

Koskinen has received prestigious awards for his works, including the Compasso d’Oro Award 2004 for his Muu chair, the Torsten and Wanja Söderberg Prize 2009, the Wallpaper Design Award for his Sofabed in 2010, and the Kaj Franck Design Prize 2014.
