So British !

 

Une innovation qui stimule les sens ...

Une combinaison de technologie, de design intemporel et de luxe abordable Que voulez-vous d'autre?

 

Russell Kauffman a relevé le défi il y a quelques années de lancer sa propre marque de haut-parleurs. Pas facile de trouver quelque chose d'innovant au milieu  des nombreux intervenants sur le marché de la hi-fi ...

Et il a réussi ! En commettant de magnifiques produits de l'artisanat européen à un prix abordable. 

 

Les Russell K Red 100 et Red 50 sont les premiers haut-parleurs développés par Russell Kauffman. Ensuite, le Red 150 est arrivé et en 2017, les floorstanders Red 120 ont suivi .

 

Produit de l'année 2014 au Royaume-Uni, un prix EAR aux Pays-Bas, lauréat du groupe HiFi Choice, hautement recommandé par HiFi Pig ... Ces prix ne font que confirmer toutes les qualités musicales de cette production !
