Crossover Questions

My receiver's high/low pass crossover slope is 12/24db. I set it to 120hz. Does this mean that a 120hz signal coming from my main speakers will be 12db less than a 150hz signal?
Also, will a 60hz signal be 24db less, or only 12db less, than those above it? And what happens to those frequencies between 60hz and 120hz? Thanks.

I can only guess with the info here so take it for what its worth.
the attenuation at 120 Hz should be 0 the each octive below will result in a 24dB reduction.

AllTheTimer,
It means that for the sub anything over 120hz is attenuated 12db/octave, and for the speakers anything below 120hz is attenuated 24db/octave.
This means that at 60hz your speakers have dropped 24db. Between 60hz and 120 hz the sub picks up. If you were to see this graphically you would see the subs frequency response go straight and drop off at 12/db per octave at 120hz, a decent slope, and the speakers would be straight until 120hz, then drop off steeply at 24db/octave.
