The word is getting out: Piattino Caster Cups are the most effective caster cups for acoustic insulation of piano sound.
Piano Forte Supply is the importer and North American source for Piattino caster cups from Germany. The Piattino caster cups are designed put an acoustic break between the piano and the structure of the building. This eliminates or reduces the direct vibration going into adjoining rooms, especially into the rooms below.
This product was designed and is produced in Germany, where the majority of people live in close proximity to others, in apartment buildings, town homes and the like. The product development was in response to an acute need for a product which reduces the impact of piano playing on neighbors.
