I had the LFE and crossover both at the same frequency because the person at Meridian USA tech support said they are the same thing, but one is for material without an LFE Channel header, and the other is for surround material that is for an LFE channel. So, he said, they both do the same thing for different formats.
They aren't the same thing. One governs the high pass filter for the main speakers, the other governs the low-pass filter knee point. You want the knee point to extend out past the crossover point.

I have always set the LFE crossover to 150Hz.

Technically speaking, the LFE crossover should only be valid on LFE content, otherwise, it's a subwoofer crossover.

I ideally want my crossover at 80Hz. I only lowered it to 35Hz as an extreme for testing purposes. I have tried it with all those settings 'on' as well as 'off' already, unfortunately, still no change.
What are you using to measure the differences? Any knid of SPL meter or just your ear?

How long should the slope be after the crossover for these? My sub is playing output all the way to the 100 Hz where the disc stops, and my speakers start playing output at around 30Hz (I think this is because of the small setting, not because of the crossover, as the crossover appears not to work on my setup so far). At 100Hz the sub is no less loud than it is at 50 Hz, I would think the slope wouldn't be that long...
Then something is wrong, as the slope is 24dB / octave above the High-pass point. So it if was set at 35Hz, but 100Hz it should be very low in comparison.

Also, what disc / test tracks are you using?
I'm using an SPL meter to measure everything.

I'm using the Revel B-15a sub parametric EQ setup disc. The sin waves are 3 Hz bandwidth warble tones. Also, using the Meridian built in sin waves the crossover isn't taking effect eitherr though the US Tech dept. said that it doesn't work like that, but I get the distinct feeling that they have no idea how it really works when talking to them and asking them... They are reading what it says in the manual and very liberally translating it to their benefit, not mine.

I'm using tracks 4 through 32. These are tones ranging from 20Hz to 100Hz.
