In a nutshell, the SubPac is a subwoofer that has been specially designed to help a user feel what he or she is listening to, which will certainly evoke more emotions compared to just hearing it. At a glance, the SubPac does not look anything out of the ordinary, where it seems to resemble one of those devices that are strapped onto a regular chair, where it is then transformed into a massage chair. It is, however, “not a vibration device”, but has been described as a “sub-woofer that generates a dynamic, rich and accurate tactile representation of whatever sound you input.”
