Project Debut Aluminium Sub Platter The Project Debut Aluminium Sub Platter improves your vinyl playback by upgrading the standard sub platter. With a high tolerance machined aluminium design, the sub platter adds mass to the turntable, damping vibrations. Enhance the speed and accuracy of your turntable with the Debut sub platter. It causes a significant increase in the total mass of the platter and the drive system, which in turn leads to further suppression of the noise and resonances that are not desired. Besides that, the higher precision in production will also help improve the overall speed accuracy. Mass increase enhances the short term speed stability, or in other words, improves Wow & Flutter specification. Thereby producing better sound reproduction.
