Here is a manufacturer, a true real, not an assembler who climbs into its boxes loudspeakers whose user does not know the references or the origin. It's a secret and it's incredible. At RCF all loudspeakers are produced by RCF in its factories with very high quality manufacturing. RCF is the first audio manufactory in Europe. By buying a manufacturer's product, a real manufacturer, the user has a guarantee of fast supply in case of need of renewal or breakage (it happens!) And especially the certainty of being able to get the transducers for many years even those possibly manufactured under specifications. RCF is a legendary brand.
