To find your local retailer, either click the 'Buy In-Store' button on your product page for exactly the right recommendation, or head to our comprehensive Where To Buy tool.
If you want the added convenience of only having to pop-in to store when you know the product you want has arrived, you can use our Click & Collect-style checkout process. With Buy Now, Collect Locally, your purchase takes place online and the product is then delivered direct to your local supporting retailer; ready for you to collect when you're ready.

The Speed Box S2 offers a functional and convenient upgrade for many Pro-Ject turntables with a 16V AC motor that do not already have built-in speed control.
The Speed Box S2 acts as an AC generator for the turntable, replacing the fluctuant supply from a normal 16V power supply and regulating it. The result is a clean power signal that allows the motor to perform optimally. The added convenience is that the Speed Box S2 can shift frequency, for easy changing between 33 and 45RPM at the push of a button.
Inside, the Speed Box S2 makes use of high-quality materials in the quartz-controlled oscillator and filter circuits. Externally it is stylish, compact and minimal - matching any other Box Design S2 Line component.
Connection is simple, as the Speed Box S2 is supplied with a link cable that plugs into your turntable instead of the normal power supply. There is also a wide range of compatibility (see below), and in some cases the Speed Box S can even add 78RPM compatibility, when partnered with a special Speed Box Pulley.
Please Note: The Speed Box S2 will not work with newer Pro-Ject turntables that feature a DC power supply. It will only work with older AC powered turntables that feature an external 16V power supply and do not already have built-in speed control.
