Have never seen that necessary on any system I've heard or owned. Also didn't see where you have the transition set on the sub.... max htz before it transitions to the satellites. Very sincerely think there is something wrong with the sub amp, unless you have the transition point set at the absolute minimum (lowest htz on the dial) . That would /could explain why it isn't showing itself very much.

When using speaker level in and out, does the Hz knob even do anything?   I think the integrated passive x-over is likely at a fixed point.   My best guess is that the sensitivity on the satellites is much higher than on the sub.   

I also considered a polarity issue from the amp to the sub, but I don't think it would play nicely without the satellites if that were the case.   Maybe a polarity issue to one of the satellites?

Or maybe the level pot is dirty.

Ive been trying to find a good spot for a tiny Mirage sub in my 2 channel system. For my room, I may just need a second sub to balance things out. The crawl method works, but the sub was out in the middle of the floor in a footpath.

I've found that running leads from amp to line level on the sub and then leads from amp to speakers. NOT using line out on the sub to other speakers. It works better for me.

You could try to get the sub up off the floor. Sometimes raising it 1/4 the distance from floor to ceiling works, 2' for 8' ceilings. Make sure whatever you use is solid.

There's also the rule of thirds, full moons, garlic, and maybe putting a ring ground up bricks around the sub.

That will certainly give more bass as the sats are running full range.   Of course the downside may be that the sats are running full range.   It is very system dependent if that will be better or worse.

Ah yes, I was assuming the sat's had internal crossovers blocking the lower frequencies, it's very possible the crossover is in the sub.

I should clarify that I use my method with full range speakers, I like the sub to extend their range a little lower and give some better impact and resonance.
