    I've read the above thread and haven't found an exact answer to what I'm looking for. OK here goes...
    I have my Yammy RX-V530 set to ALL SMALL. Now the Yammy then sends anything 90Hz and below to the sub. I also have the sub's LFE IN hooked up to the receivers LFE OUT. I dont have a crossover setting within the AMP, I need to use the dial on the back of the sub, which I have dialed all the way up to 150Hz. Does this crossover even control the LFE input, say I turned it down to 100Hz, would I lose the range from 100-120? I realize that leaving the crossover opened up all the way is the way to go, but I was just curious as I want to understand fully how my system operates. Thanks in advance for any replies.

    You wouldn't exactly loose the 100-120hz range of the LFE signal. It would just be attenuated at the rate of the slope of your subs variable low pass filter. Likely 12dB/octave (a doubling of frequency is an octave, so like 16-32, 32-64, 64-128 etc).
