The Pro-Ject XAB Counterweight is a genuine factory replacement weighing 120 grams, supplied as the standard counterweight for the Pro-Ject XA B true-balanced turntable and other Evolution-series 10" aluminium tonearms. It is listed in the Pro-Ject parts catalogue as counterweight no. 34 under manufacturer part number 1944978034.
The counterweight is machined to fit the tonearm stub directly and incorporates a TPE (thermoplastic elastomer) insert that decouples the weight from the tonearm tube. This reduces resonance transfer from the cartridge and platter back into the arm, helping to preserve detail and lower the noise floor during playback.
This 120g counterweight is the correct balance mass for moving-magnet and moving-coil cartridges with an overall weight between 5g and 10g, which covers the great majority of cartridges typically fitted to Pro-Ject's X-series and Evolution tonearms - including the factory-supplied Pick it Pro Balanced.
Useful as a replacement for a lost or damaged original, or as a spare when fitting different cartridges to the same arm.
Compatibility
- Pro-Ject XA B turntable (factory-fitted counterweight)
- Pro-Ject Evolution-series 10" aluminium tonearms requiring counterweight no. 34
- Cartridges with a total weight of 5-10g
