Randy, it may just be the room. Your friend has a very small square room which may be exciting certain low frequencies (maybe giving that intro scene a boost). I have a room almost that same size, and right now I'm trying to place some subs. Unfortunately where I sit, I get a huge suck out in bass, if I take three steps to the right (near the corner), boom, instant bass.
It doesn't take much to pressurize small rooms. Used to have a VTF 3 in a 10x10 room. Sometimes it felt like the walls were flexing.
