Cud some1 please explain to me what exactly "effective damping factor" is. This is how the JBL/Crown amps measure their damping factor and I have no idea how to relate it to the normal way a damping factor is measured considering its a really really low number in the single digits.

LOl i know sum1 would say that, I know what dampening factor is, i just don understand jbl's method of rating it, take a look at the specs page for the JBL BPX2200.1 and u'll understand. If the amp's actual damping factor was 6.xx itd be terrible and it also calls it "effective damping factor" so i know it must be some other method of measurement.

I don't know the answer, and I haven't looked into the new ratings system too much either to know if it is a part of that...

But, if your concerned about the damping factor not being adequate, I highly doubt its anywhere near audible, unless you run the thing at a ridiculously low ohm load, in which case, I'm sure you wouldn't be doing it for SQ so DF really wouldn't be a concern.

If you not concerned with that and just want to know the answer...you could call JBL.

" Damping Factor:is a measure of a power amplifier's ability to control the back-emf(electro-magnetic force) motion of the loudspeaker cone after the signal disappears. The damping factor of a system is the ratio of the loudspeaker's nominal impedance to the total impedance driving it. "
So, depending on what impedance the speaker(or resistor) was when the amp was tested at whatever frequency, that's whatever spec was posted as maximum guaranteed or better.
