Duff, you didn't describe your amp and sub. If the amp is multi-channel and has a crossover between the sub and mains at about 80-90hz, that's all the crossover needed; the sub crossover should be set to by-pass(if available) or turned up to the max to get it out of the way of the amp crossover. If not, then the M22s will run full-range and the sub crossover has to be used to fill in the M22 bass below about 70-80hz. It's not possible to say what setting, especially on an unknown sub, will do this, particularly since the markings on the sub crossover often aren't very accurate. Experiment.
The sub should be right in the corner closest to the speakers and in that location phase should probably be set at 0, but again, experiment to see if a different setting gives better bass.
