Dear simracers After studying a lot of comments there are some questions again: Im planing to buy 2 basshakers (I think the mini lfe) and I have a Playseat evolution. What do you recommend to position the bs. left and right of the seat ? which height (a little under the seat or higher?) or is it better to under the seat L + R. If I going in the chasis mode and I have the BS on the side of the seat, do I feel the roadnoise/BpM or its necessery to have a 3. under the seat? I dont have space inside the pc for a sound card. Does it work with a external usb card? many thanks for your help.
