Today I got my SubPac in the mail from Canada. Some months ago I decided to support the Kickstarter project for these things. The SubPac is a device that is seated between the chair/sofa and your back. Connect it to a sound source and it will transfer low frequencies directly to your body. It lets you FEEL the bass. And believe me, it really works. It feels very similar to being in a club with a big sound system and you feel the bass though all of your body, not just the back. I’ve tried it for several things already, producing music (Wow this changes everything!), listening to music, playing games and watching movies. It is awesome! I love it!
