Sound should be more than just heard. It should be felt, pulsing through your
body like a grenade exploding behind you, the rumble of heavy turbulence, or footsteps around the corner. Our
superior audio products combined with real tactile feedback provide a complete
sensory experience and increased situational awareness.

How Can I Actually Feel Sound?
A bass shaker operates in much the same way as a normal
electrodynamic loudspeaker. The shaking action comes from a "voice coil" which
is spring-mounted within a narrow gap in a powerful magnet. When current passes
through the coil, it creates a magnetic field, and that field pushes the voice
coil one way or the other, depending on the direction of the current. Send the
coil electricity modulated by an audio signal and it will vibrate in
synchronization with that signal.
Hooking up the AudioFX is a snap.

In a normal loudspeaker, the voice coil is connected to the
speaker cone, and that lets it "couple" to the air, creating sound waves. The
cone moves back and forth and creates the same compression and rarefaction waves
that any object vibrating at the same frequency will. In a bass shaker, there's
no cone and rubber or paper cone surround; instead, there's the transducers
located on the top of the shaker, and the voice coil has a piece of metal
connected to it. The metal oscillations shake the body of the transducer and
whatever it's connected to, while still allowing the coil to move freely. So you
get a clear sound, smooth bass vibration and not an obnoxious buzz.
Transducers in the AudioFX headset and Intensor gaming
chair respond to the low bass frequencies, some even below a level typically
heard by the human ear. These frequencies are what are then transformed into the
vibration effect that makes these products so special. Not only do you get to
literally feel the action like you would if you were sitting on a subwoofer, but
because in a headset you get true L/R stereo separation, you get our exclusive
directional force feedback. This means you can actually feel sounds from the
direction in which they are originating, such as footsteps approaching from your
left. Additionally, the sensation is sensitive enough to differentiate between
the rumbles of a Cessna engine compared to the Concorde.
