1) Don't get me wrong, the actuator does not vibrate at 26,000 Hz, it is the feel.
2) The actuators can reproduce positions, slow movements, and continuous range of vibration frequencies from 0 to 100 Hz. The amplitude of movement is 35mm. Imagine the whole rig can move in mutiple direction at a distance of upto 35mm at 100 times per second. I am certain there is some G-force here but I just don't know exactly how much, however I was told slightly above 2G at the extreme.
3) I made an earlier mistakes that D-box uses the telemetry to decode the motion, I am partially wrong here after I clarified with them. Actually D-Box use the low frequency of the audio of the game with the game developer telling them how the low frequency is related to telemetery then D-Box write the codes for the motion.
4) Although I owned the D-box since late 2008 and know some of the guys there, however they put in so much research and patent on their system that they will never disclose much. Even till now, the only infor i know about the actuator is that she can hold upto 250lbs and period .... no spec available .... nothing. Anything wrong ask them and they will guide.
5) This system is very easy to maintained and so far no big problem.
6) D-Box is a closed system as compare to x-simulator and other motion system. In my opinion, they still cover a good range of racing title in PC.
7) I am not so sure whether motion will help in lap time, for my case is not and I am a lousy racer, so I go for immersion.
Last but not least, I think Mr. Mayaman is trying very hard to provide as much as information to the forum here but in reality DBOX did not disclose much in the first place.
