The Pro-Ject X1/X2 Alu Sub-Platter is an upgrade component designed for the Pro-Ject X1 and X2 turntables. It is crafted from aluminum, which is known for its rigidity and ability to reduce unwanted vibrations. The aluminum sub-platter serves to improve the overall stability of the platter's rotation, resulting in enhanced speed consistency and reduced wow and flutter, thereby improving playback quality. The sub-platter is precision-engineered to fit perfectly within the existing turntable setup and can be easily installed by users looking to enhance their turntable's performance. This component is typically used in conjunction with a compatible belt-driven turntable system, providing a complementary upgrade to the existing platter design.
