Thorens TAB 1600 Absorber Base The Thorens TAB1600 Absorber Base was specially developed for the improved installation of turntables. Made of a MDF base plate, which is additionally attenuated by a layer of fabric, it is combined with an acoustic foam in sandwich construction. This unique combination highly efficiently decouples the turntable from its underground, so preventing acoustic feedback. Contrary to the principle of coupling by spikes, which often can negatively influence the sound quality by vibrational coupling to the ground, we use the principle of decoupling in the TAB1600 to neutralise the negative impact of structure-borne sound from the turntable. 1
