[QUOTE="qtipextra, post: 1181490, member: 555270"] Fs is the free air resonant frequency ...... the freq. that it vibrates the most in free air re is the actual impedance (ohms) qms is mechanical q.......spider surround cone weight qes is electrical q.......magnet strength VC qts is total q q is the subs tendancy to resonante at fs sd is cone area Vas is the volume of air that has the same complience as the subs suspension......... basically tells you the looseness of the suspension (bigger vas=looser sus) xmax is how much it moves one way, u can go beyond xmax on some subs (not much on the xxx) but anything over xmax is non-linear (shitty sounding) bl is the strenth of the motor spl is how loud it is from one meter away wih one watt rms is the continuous power it can take max is usually the peak power it can take for a split second [/QUOTE]
