I promised to post my opinion between the plattform based 4 horizontal actuator Odyssee XL System and a Quest Love seat with 4 vertical extended Lift (1.5 inch) actuators.
After I have played some time with both systems I come to the decission that extreme vibrations and pushes are better defined by the horizontal actuators of the Odyssee plattform system. The Quest system wins if your goal is to achieve a maximum feeling of motion.
Both systems are amazing and it is a difficult decission and more a matter of personal taste and of course the kind of movie you are watching. I discovered that motion isn´t that important for me but extreme vibrations and hard pushes are. So I give the plattform based Odyssee system my personal preference.
Or in other words, it´s good to have both
best regards to all of you !
