[QUOTE="All_Logix, post: 7753995, member: 628274"] Sure, If you recall from trig, I know it's painful, a sine wave has an equal value above and below the x-axis. In electricity, AC voltage, which is what audio systems use, makes this same wave (ideally). So you will have say, 15v, then -15v, this causes the speakers to move one direction when a positive voltage and the other direction when a negative voltage due to electromagnetics. If you want to know more about this I would google "how a speaker works" Anyway.... Hz is the number of times per second that this voltage goes from its most positive value to its most negative value. Our ears can hear the movement of a speaker at 20Hz-20kHz, or 20 times per second to 20000 times per second. Subwoofers are large and meant for "low" frquencies. ~20Hz-100Hz. Some people run them higher for SPL comps. but for street bass, dont.
