Xtension 12 Evolution - Official Pro-Ject Audio Systems USA

Pro-Ject’s Xtension 12 incorporates over 20 years of experience in turntable design and manufacture.

The Xtension 12 represents their latest technological efforts to address mass-decoupling and resonance reduction. Beginning with the mass-loaded magnetically floated sub-chassis and the precision balanced sandwich alloy platter (recycled vinyl/alloy), the foundation of this system weighs in at a super-heavy 55lbs.

Additionally, Pro-Ject employs magnetic decoupling feet to thwart airborne or mechanical vibration from disturbing playback. This mass and isolation create an environment of extremely low resonance allowing music to emerge from an ultra-silent black background. An AC motor with a two-step pulley drive with Electronic Speed Control maintains perfect pitch and rhythm resulting in inaudible wow, flutter and noise.

There’s even a built-in spirit level to assist in setting the height-adjustable magnetic footers. Further reducing noise and vibration is the isolated Sorbothane mounting board for the 12″ carbon-fiber tonearm.

The conical arm and unified headshell are fabricated from a single piece of carbon fiber to avoid problems associated with standing wave reflections. Single screw fixing of the arm tube allows for easy rotation for adjustment of needle azimuth. Additionally, the arm is fully adjustable for VTA. A high-performance 123cm phono interconnect cable is included.
