Basically is a tactile bass system or a "Silent sub" you put on your seat. I tried someone's demo version and I had to have one. The new consumer version ships any day now.
It is responsive from 5-125hz
You can listen to a movie on headphones, and still experience the LFE.
If you are a producer, it can help you mix your low end and see how your kicks and bassline are going to sit in the mix.
"SubPac is a tactile audio system, designed and developed in
Toronto, Canada. The SubPac consists of a combination of tactile transducers, vibro-tactile membranes, electronics and textiles, designed to deliver a physical dimension of sound. SubPac is available in a wearable and seatback format. The device was intended to move music hardware technologies in this area past simple ‘vibrating devices’ to deliver a complex and nuanced experience, to create an accurate tactile representation of whatever audio input is used. Outside of music production and enjoyment, the SubPac has a wide range of applications such as gaming, virtual reality (VR) and film enjoyment."

Here's a review, keep in mind it is for the early adapter version, I think this was the kickstarter version. Like I said the S2 is shipping any day now.
