Xtension 10 shares much with its big brother, Xtension 12. Designed with a smaller footprint and with a 10″ tonearm, it delivers much of 12’s performance in a more compact and less expensive package. Incorporating decades of experience in turntable design and manufacture, Xtension 10 represents Pro-Ject’s technological efforts to address mass-decoupling and resonance reduction. Beginning with the mass-loaded, magnetically-suspended sub-chassis and the precision-balanced sandwich alloy platter (recycled vinyl/alloy), the foundation of this system weighs in at a just under 50 lbs. Additionally, Pro-Ject employs magnetic decoupling feet to prevent mechanical vibration from disturbing playback. The mass and isolation create an environment of extremely low resonance allowing music to emerge from an ultra-silent background.

A DC-driven AC motor with a two-step pulley and electronic speed control maintains perfect pitch and rhythm resulting in inaudible wow & flutter. Further reducing noise and vibration is the isolated TPE mounting board for the 10″ carbon-fiber tonearm. The conical arm and integrated headshell are fashioned from a single piece of carbon fiber to avoid problems associated with standing wave reflections. Single-screw fixing of the armtube allows for easy azimuth adjustment if needed. The arm is fully adjustable for VTA and includes a high-performance, purpose-designed DIN-RCA phono cable (1.23m).

Inside the Plinth

RPM 9 & 10 Carbon, Xtension 9, 10 & 12 Evolution, and Signature 10 & 12 use plinths that are more than meets the eye. These high-end turntables not only use multi-density fiber (MDF, which absorbs resonance), but inside the plinths are also “central gravity points” filled will steel pellets. Drawing harmful resonance to the central gravity point all but eliminates the potential for plinth and bearing noise to reach the tonearm and cartridge. Pellets are used as opposed to a solid alloy due to their dispersion effect where a solid alloy may resonate. This design heightens the overall mass of these turntables as well, a well-known approach to optimizing sonics.
