Brand new in box, never used! One set of four Alto Extremo NeoFlex XL high end audio tuning feet. Just one of the best and most exclusive equipment feet. They are based on the principle of magnetic repulsion. Two extremely strong Neodym-magnets hold the weight of the overlying Hifi-device. Thus the NeoFlex Absorbers are an ideal instrument to optimize your High End device. Energy is dissipated by the device perfectly through the absorber and destroyed in the absorber. Low profile, yet extremely strong. (There is nothing comparable, worldwide). Stepless adjustment and self-leveling. (Therefore can also be used four or more absorbers). Screen caps to avoid disturbances due to the magnetic field. (Suitable for CD-players and turntables). Your Hifi-device wins even more on precision and resolution. The NeoFlex XL is an ideal tool to optimize your High-End system. Once inserted, you will not want to miss the NeoFlex Absorber again! Maximum load of one NeoFlex XL is 15kg. Retail price is 1.749 euro for the set of four. Check our other listings for more interesting items. Free shipping worldwide!
