SME Series M2 Tonearm

Series M2 Tonearm

The Series M2 embraces three models the M2-9, M2-10 and M2-12 offering pivot-stylus dimensions covering virtually all turntable requirements.

These arms offer at reasonable cost, meticulous build quality with all the most important features including lightweight stainless steel tonearm, detachable magnesium headshell with azimuth adjustment, tungsten balance weight, superb quality ball race bearings etc., and a level of stiffness and rigidity to suit all types of cartridge.

These precision pick-up arms embody well tried SME principles and are suited to a broad range of cartridges including those of medium and low compliance.

Series M2-9 is the standard arm having a pivot-stylus dimension of233.2 mm (9.18”) and will therefore be the one most frequently used.Typical effective mass 9.5 grams.

Series M2-10 is identical except that the pivot-stylus dimension is 239.3 mm (9.42”) a difference that suits the layout of some decks. Typical effective mass 9.6 grams.

Series M2-12 has a pivot-stylus dimension of 308.8 mm (12.16”). Distortion caused by lateral tracking error is at least 25% less than possible with a nine inch arm. However effective mass will be typically 12.0 grams. Also, a turntable designed for 12-inch arms must be selected.

The internally damped tonearm of highly polished stainless steel provides sparkling uncoloured reproduction. A unique single element balance system caters for cartridges weighing 5 to 12 grams. After balancing tracking force is applied by forward movement of the weight ensuring the lowest system inertia. The weight moves on a precision screw thread with backlash eliminator allowing exact setting of vertical tracking force.

The M2 shell is pressure die-cast in magnesium for lightness and rigidity.

A collet of ingenious design affords ‘one-piece’ rigidity and allows azimuth correction to be made before final tightening.
