If you're just starting to learn about the Spank-O-Matic line of machines, please start with the SOM II. The pictures and text on this page focus on the uniqueness of the SOM II XP, and mostly ignore the features shared with the standard SOM II.
XP... extra power! If you need the most powerful machine spanking available at your fingertips, this is the machine for you. The SOM II XP uses twin valves and cylinders, developing twice the power of the original SOM II, all controlled withe the same computerized flexibility and accuracy. This only difference in the XP is the double-barrelled head unit. All other components are identical to the standard SOM II.
The mechanics of pneumatic power mean the parallel cylinders can put more than 500 pounds of force behind each stroke. Additional leverage against the spanking arm take advantage of this massive power to create higher accelleration and a significant upgrade in spanking force vs. the already-powerful SOM II (estimated at a 40% increase, although mechanical assessment of actual striking power is in the works). This is a machine to respect! As always, use the higher incoming pressures and power settings with due care! Higher levels of play within the range of the SOM II XP are not recommended with non-Lexan end effectors such as the cane set or oak paddle.
Please note that I do NOT recommend the SOM II XP to the average spanking machine user, only to those REQUIRING extreme striking levels. This extra power comes with a cost. The XP model uses roughly twice the air volume of the standard SOM II, at any given power level. The mild air exhaust sounds are likewise doubled. The SOM II was designed to fully meet the needs of the vast majority of machine spanking afficianados.
Again, please see the SOM II pages for a more comprehensive description of the SOM II features, technology, and advantages.
