The ButtKicker is an excellent low frequency haptic transducer, but what it drives (your chair/sim rig/platform/floor/furniture) will have a direct influence on the total system response. Good low frequency response is a combination of both the ButtKicker transducer and the surface/platform driven by the ButtKicker transducer. The platform, whether it is a suspended wood floor, or a platform built under your furniture, needs to be able to move/shake at low frequencies. A tight (usually small) platform may vibrate freely at higher or midrange frequencies but not have the freedom to move for the low frequencies.
