I just have an rca cable run from the receiver to the input on the Sub. Bypass on, and I just adjust the level at the sub.

The Omni has only 4 high level inputs and no outputs so I can't figure out how to run the signal through the sub and adjust cross over at the sub, other than to turn off the bypass and adjust there.

It really sounds good though even though sending the whole signal to the sub and mains is considered bad form, the blend seems to be really good. Getting it better is the whole idea of course.

I just had an idea, if I unplug the mains and listen to just the sub will that give an idea of the signal and its character - full range or not?
