Does anyone have a device which can measure Hertz? There are a couple scenes in Reloaded where you can feel the bass "ripple" across the room. (I didn't notice this sensation in the first Matrix) One scene in particular, is the bullet-time sequence of the shootout between an agent and Trinity while she is falling backwards out the window. A couple of times when the guns are fired in this slow mo sequence, I can feel the bass move through my seating. What Hertz level is this? I wish I had a device to measure bass frequencies, does Radio Shack have anything like that? I'm using a Polk 505 subwoofer.
